Understanding Scalp Tumors: Types, Causes, and Prevalence

Scalp tumors are abnormal growths that develop on the skin covering the head, extending from the eyebrows to the back of the skull. These lesions can be either benign (non-cancerous) or malignant (cancerous), with the vast majority being benign. Understanding the nature of these growths is crucial for proper diagnosis and treatment.

Interestingly, studies have shown that approximately 93-99% of scalp tumors are benign. Of these benign growths, about 40-50% are cysts, with trichilemmal (pilar) cysts being particularly common on the scalp. Other prevalent benign tumors include lipomas (30%) and melanocytic nevi (28%).

While malignant scalp tumors are relatively rare, accounting for only 1-2% of all scalp tumors, they represent about 13% of all malignant skin tumors. The most common types of malignant scalp tumors include basal cell carcinoma (41%), squamous cell carcinoma (17%), and less frequently, cutaneous metastases, adnexal tumors, angiosarcomas, and lymphomas.

Benign Scalp Tumors: Identification and Characteristics

Benign scalp tumors come in various forms, each with distinct features that can aid in identification:

• Epidermoid cysts: These appear as firm, flesh-colored or yellow papules or nodules, often with a central punctum that may exude a foul-smelling substance.
• Dermoid cysts: Characterized by firm, dough-like lumps composed of epidermal and dermal tissue components.
• Seborrheic keratosis: These lesions have a “stuck-on” appearance and can be flat or raised, with varying colors and sizes. They’re more common in adults over 60.
• Melanocytic nevi: These are localized proliferations of melanocytes that can be flat or raised. Scalp variants have a higher likelihood of displaying dysplastic histological features.
• Trichilemmal cysts: These keratin-filled nodules originate from the outer hair root sheath and lack a central punctum.

Malignant Scalp Tumors: Warning Signs and Key Features

Malignant scalp tumors, though less common, require immediate attention due to their potential for serious health consequences. Here are some key characteristics of common malignant scalp tumors:

• Basal cell carcinoma (BCC): Often appears as a pearly, flesh-colored bump or a pinkish patch of skin. It may also present as a sore that doesn’t heal or bleeds easily.
• Squamous cell carcinoma (SCC): Typically manifests as a firm, red nodule or a flat lesion with a scaly, crusted surface. It may also appear as a sore that doesn’t heal.
• Melanoma: Can present as a new, unusual-looking mole or a change in an existing mole. Look for asymmetry, irregular borders, color variations, diameter larger than 6mm, and evolution over time (the ABCDE rule).
• Angiosarcoma: Often appears as a bruise-like lesion that doesn’t heal, or as a raised area of purplish skin.

Diagnosis of Scalp Tumors: From Visual Inspection to Biopsy

Accurate diagnosis of scalp tumors is crucial for appropriate treatment. The diagnostic process typically involves several steps:

1. Visual examination: A dermatologist will carefully inspect the lesion, noting its size, shape, color, and any unique characteristics.
2. Dermoscopy: This non-invasive technique uses a special magnifying device to examine the skin’s surface structures in detail.
3. Biopsy: If a malignancy is suspected, a small sample of the tumor is taken for microscopic examination. Types of biopsies include:
   • Shave biopsy: Removal of the top layers of skin
   • Punch biopsy: Removal of a small, circular section of skin
   • Excisional biopsy: Complete removal of the tumor
4. Imaging: In some cases, CT scans or MRI may be used to determine the extent of the tumor, especially if it’s suspected to be malignant.

Treatment Options for Scalp Tumors: From Observation to Surgery

The treatment approach for scalp tumors varies depending on whether the growth is benign or malignant, as well as its size, location, and the patient’s overall health. Here are some common treatment options:

For Benign Tumors:

• Observation: Some benign tumors may not require immediate treatment if they’re not causing symptoms or cosmetic concerns.
• Surgical excision: This involves removing the entire tumor and is often used for larger or symptomatic benign tumors.
• Cryotherapy: Freezing the tumor with liquid nitrogen can be effective for certain types of benign growths.
• Laser therapy: Some benign tumors can be removed using targeted laser treatments.

For Malignant Tumors:

• Mohs micrographic surgery: This precise surgical technique is often used for basal and squamous cell carcinomas, allowing for complete tumor removal while preserving healthy tissue.
• Wide local excision: Used for melanomas and other aggressive skin cancers, this involves removing the tumor along with a margin of healthy tissue.
• Radiation therapy: May be used alone or in combination with surgery, particularly for tumors that are difficult to remove surgically.
• Chemotherapy: Systemic or topical chemotherapy may be used for certain types of skin cancers or if the cancer has spread.
• Immunotherapy: This treatment boosts the body’s natural defenses to fight cancer and may be used for advanced cases of skin cancer.

Prevention and Risk Factors: Protecting Your Scalp from Tumors

While not all scalp tumors can be prevented, there are steps you can take to reduce your risk, particularly for malignant growths:

• Sun protection: Use a broad-spectrum sunscreen on exposed areas of your scalp, especially if you have thinning hair or are bald. Wear hats or other protective headwear when outdoors.
• Regular self-examinations: Check your scalp regularly for any new growths or changes in existing moles or lesions.
• Avoid known carcinogens: Limit exposure to substances known to increase cancer risk, such as certain chemicals or excessive radiation.
• Maintain a healthy lifestyle: A balanced diet, regular exercise, and avoiding smoking can help support overall skin health.

Understanding risk factors is also crucial. These may include:

• Fair skin and light hair
• History of sunburns or excessive sun exposure
• Family history of skin cancer
• Weakened immune system
• Exposure to certain chemicals or radiation

When to Seek Medical Attention: Red Flags for Scalp Growths

While many scalp tumors are benign, it’s important to know when to consult a healthcare professional. Here are some signs that warrant medical attention:

• Rapid growth or change in size of an existing lesion
• Changes in color, shape, or texture of a mole or growth
• Bleeding, itching, or pain associated with a scalp lesion
• A sore that doesn’t heal within a few weeks
• Any new growth that persists for more than a month
• Asymmetry, irregular borders, or multiple colors in a mole (following the ABCDE rule for melanoma)

Early detection and treatment of scalp tumors, especially malignant ones, can significantly improve outcomes. Don’t hesitate to consult a dermatologist if you notice any concerning changes on your scalp.

Living with Scalp Tumors: Coping Strategies and Support

Dealing with a scalp tumor, whether benign or malignant, can be emotionally challenging. Here are some strategies to help cope:

• Educate yourself: Learn about your condition from reliable sources to better understand your treatment options and prognosis.
• Seek support: Connect with support groups or counselors who specialize in helping patients with skin conditions or cancer.
• Maintain open communication: Keep your healthcare team informed about any concerns or side effects you experience during treatment.
• Focus on overall health: Maintain a healthy lifestyle to support your body during treatment and recovery.
• Consider cosmetic options: For visible scalp tumors, explore options like wigs, hats, or scalp micropigmentation to help you feel more confident.

Remember, many people successfully manage scalp tumors and go on to lead healthy, fulfilling lives. With proper care and support, you can navigate this challenge effectively.

Advances in Scalp Tumor Research: New Horizons in Diagnosis and Treatment

The field of dermatology and oncology is constantly evolving, bringing new hope for patients with scalp tumors. Some recent advancements include:

• Improved imaging techniques: Advanced imaging methods like confocal microscopy are enhancing non-invasive diagnosis of skin lesions.
• Targeted therapies: New drugs that target specific genetic mutations in cancer cells are showing promise in treating advanced skin cancers.
• Immunotherapy advancements: Ongoing research is refining immunotherapy approaches, making them more effective and reducing side effects.
• Artificial intelligence: AI algorithms are being developed to assist dermatologists in identifying potentially malignant lesions more accurately.
• Minimally invasive treatments: New techniques are being explored to treat tumors with less scarring and faster recovery times.

These advancements offer hope for improved outcomes and quality of life for individuals dealing with scalp tumors. As research progresses, we can expect even more innovative approaches to diagnosis, treatment, and prevention of these conditions.

Understanding scalp tumors, from their types and causes to diagnosis and treatment options, is crucial for anyone concerned about their scalp health. While the majority of scalp tumors are benign, it’s important to remain vigilant and seek medical attention for any suspicious growths. With early detection and appropriate treatment, most scalp tumors can be managed effectively, allowing individuals to maintain their health and quality of life. As research continues to advance, we can look forward to even better outcomes for those affected by these conditions.

What are scalp tumours?

The scalp comprises the area from the back of the head (beginning at the superior nuchal lines) to the eyebrows (supraorbital margin). Scalp tumours are benign or malignant cutaneous lesions which arise on the scalp.

Who gets scalp tumours?

Scalp tumours occur worldwide. Most scalp tumours (93–99%) are benign as opposed to malignant.

Approximately 40–50% of benign scalp tumours are cysts with an estimated 20% incidence in Western populations. Trichilemmal (or pilar) cysts are especially common and it is estimated 80% of these cysts occur on the scalp. The remaining proportion of benign scalp tumours primarily comprises lipomas (~30%) and melanocytic naevi (28%). Seborrhoeic keratoses and actinic keratoses are increasingly common with age and the latter develop particularly as the hair thins.

Although only 1–2% of scalp tumours are malignant, they comprise approximately 13% of malignant cutaneous tumours. The most common (in decreasing order of commonality) malignant scalp tumours include basal cell carcinoma (~41%), squamous cell carcinoma (~17%), cutaneous metastases, adnexal tumours, angiosarcomas, and lymphomas.

What causes scalp tumours?

The causes of both benign and malignant scalp tumours are varied and can depend on the underlying tissue of origin and associated co-morbidities. Scalp tumours can arise from cells in both the skin (epidermis and dermis) and deeper tissue layers. It may also originate from other cells in the body due to metastases.

What are the clinical features of scalp tumours? 

Both benign and malignant scalp tumours can occur elsewhere on the body but may have different physical features. The exact features displayed are dependent on the originating site and cells of the tumour, summarised in Table 1 and 2.

Table 1. Benign scalp tumours

Table 2. Malignant scalp tumours

Squamous cell carcinoma	Keratinocytes	A malignant proliferation of keratin producing cells extending beyond the epidermis. Scalp variants more frequently present with ulceration and have a higher propensity for recurrence.
Intraepidermal squamous cell carcinoma		Also known as Bowen’s disease. A malignant proliferation of keratin producing cells localized within the epidermis.
Basal cell carcinoma		A malignant proliferation of keratin producing cells extending beyond the epidermis. Scalp variants more frequently present with ulceration and have a higher propensity for recurrence. Pigmented or nodular subtypes are also more commonly seen and are more likely to demonstrate a melanocytic pattern on dermoscopy.
Keratoacanthoma		Rapidly growing firm circular nodule with a keratin core. A variant of squamous cell carcinoma.
Malignant melanoma	Melanocytes	Indistinct presentation of variously pigmented or nonpigmented lesions derived from a malignant proliferation of melanocytes. Scalp melanomas are more commonly seen in older men and are associated with alopecia. Compared to other body areas, there may be a higher propensity to present as recurrent desmoplastic or amelanotic melanoma. Lesions are also more likely to develop ulceration and have a greater Breslow thickness.
Malignant proliferating trichilemmal tumour	Hair follicles	Keratinized nodules or cysts derived from outer hair root sheath cells with low potential for metastasis. May develop from trichilemmal cysts.
Pilomatrix carcinoma		A low grade adnexal carcinoma derived from hair matrix cells that may manifest as skin coloured or purplish irregular papules.

Leiomyosarcoma	Myocytes	Malignant proliferation of smooth muscle cells that may also develop in the dermis or subcutaneous tissue.
Dermatofibrosarcoma protuberans	Collagen(fibrous)/histiocytes	Slow growing tumours derived from collagen that develop in the dermis. Typically manifests as red-brown to skin coloured painless lichenified plaques or fixed, firm nodules.
Fibrosarcoma		Malignant proliferation of spindled fibroblasts or myofibroblasts which are typically firm and spherical but otherwise nondescript in appearance. Generally carries a poor prognosis.
Merkel cell carcinoma	Neural	Aggressive tumours with high metastatic potential, thought to be derived from pressure receptors (Merkel cells) in the skin. Approximately 80% of cases are found to have concomitant Merkel cell polyomavirus. The most common site of development is the head and neck region. Scalp lesions are typically larger and have an even higher risk of metastasis.
Malignant peripheral nerve sheath tumour		Proliferations of one or more types of cells that compose peripheral nerve sheaths – typically originate from perineural or endoneurial fibroblasts. Associated with plexiform neurofibromas.
Lymphoma	Haematologic	A malignant proliferation of lymphocytes. Multiple cutaneous and non-cutaneous variants exist. The most commonly occurring variants on the scalp include primary cutaneous follicle centre and/or marginal zone lymphomas.
Metastases	Various	Secondary malignant proliferations that develop from the spread of a primary malignancy beyond its site of origin. The scalp can both develop malignancies which metastasize and act as a site for metastases from other body sites. Metastases commonly associated with the scalp include: Melanoma Papillary thyroid carcinoma Breast cancer Pulmonary adenocarcinoma Colorectal adenocarcinoma Hepatocellular carcinoma Cholangiocarcinoma Renal cell carcinoma Langerhans cell histiocytosis

How are scalp tumours diagnosed?

Some scalp tumours may be diagnosed through a clinical examination alone. A biopsy or radiologic workup may be necessary to confirm the diagnosis.

What are the treatments for scalp tumours?

Treatment options are dependent on the nature of the tumour, anatomical location, and underlying diagnosis. Given that malignant scalp tumours carry a worse prognosis than lesions in other anatomic areas, radical surgical excision is more likely to be recommended. Excision can be complicated by the relative lack of scalp skin mobility. Mohs micrographic surgery may be a preferable option in these cases.

Other treatments may include:

• Cryotherapy
• Electrodessication and curettage
• Photodynamic therapy
• Topical therapy (i.e. 5% imiquimod)
• Radiotherapy.

What is the outcome for scalp tumours?

Malignant scalp tumours tend to carry a worse prognosis than equivalent tumours elsewhere on the body. The exact prognosis is dependent on the specific tumour involved and the degree of invasion beyond the skin. Scalp metastases (either originating from scalp tumours or elsewhere) typically carry a poor prognosis.

Seborrheic keratosis: Symptoms, treatment, and causes

Seborrheic keratoses are common, harmless, noncancerous growths on the skin. They usually appear as tan, brown, yellow, gray, or very dark brown warty growths ‘stuck onto’ the back, shoulders, chest, or face.

Also known as basal cell papilloma or seborrheic warts, seborrheic keratoses can appear anywhere on the skin except the palms, soles, and mucous membranes. They often appear on the scalp, trunk, neck, arms, and legs and sometimes occur on the face. Some look black but are, in fact, very dark brown.

Seborrheic keratoses can look like warts but are different from warts. Warts result from a virus, such as the human papillomavirus (HPV). Seborrheic keratoses are unlikely to stem from HPV or another virus, according to Dermnet NZ. They are not contagious.

Seborrheic keratoses tend to appear from middle age onwards. Some individuals may have just one, but there will usually be several. Seborrheic keratosis is not contagious.

Over 80 million people in the United States have seborrheic keratoses. They can occur at any age but are most common after the age of 50 years.

Seborrheic keratoses may look like warts, moles, or skin cancer.

They can have the following features:

• Color: Tan, brown, yellow, gray, or skin-colored; some are very dark brown but may appear black.
• Location: Commonly on the trunk, scalp, trunk, neck, limbs, and sometimes the face. They do not affect the soles of the feet or palms of the hands.
• Texture: Can be “waxy” in appearance or rough and crusty, like a barnacle.
• Raised or not: Can look as if “stuck onto” the skin, but some are flat.
• Size: From a pinpoint to over 1 inch (around 2 millimeters to 3 centimeters) across.
• Shape: Usually round or oval.
• Sensation: Not painful but may itch or become irritated.
• Number: Ranging from one to hundreds of lesions.
• Growth: Lesions usually start as small, rough bumps and gradually get thicker and develop a warty surface. They grow slowly.

Some lesions can be light-colored and flat, like a solar lentigo, which is also known as a sunspot or “liver” spot.

On darker skin, seborrheic keratoses present similarly but are more likely to be the darker brown type.

Seborrheic keratosis lesions are rarely painful but can be annoying, depending on their position. It is important not to pick or scratch them as this can lead to bleeding, swelling, and potentially, infection.

There are many types and subtypes of seborrheic keratoses, including stucco keratoses and dermatosis papulosa nigra.

Stucco keratoses are multiple small, light tan papules or bumps with a rough texture, specifically around the lower legs and ankles.

Dermatosis papulosa nigra appears as multiple small, dark pigmented papules or bumps. Lesions often appear on the face. They tend to affect people with brown or black skin.

It can be difficult to distinguish between seborrheic keratoses and skin cancer lesions. For this reason, anyone who notices new lesions or skin changes should see a doctor.

If they already have a diagnosis, they should request an appointment if the following occur:

• a large number of growths grow in a short space of time
• the borders around the growths are irregular or blurred
• the growths are irritated by clothes and regularly bleed, as removal may be an option
• growths or sores develop and do not heal
• the growths are an unusual color, for instance, purple, reddish-black, or blue
• there is itching or irritation

People with multiple seborrheic keratoses may wish to make a yearly appointment with a dermatologist to check for changes that could be cancerous.

How do you know if a lesion is cancerous?

In most cases of seborrheic keratosis, no further treatment is necessary.

However, a doctor may recommend removing the growth in the following cases:

• It is hard to distinguish from skin cancer or the diagnosis is uncertain.
• The individual does not like it and wants to remove it.
• It causes itching or irritation, or clothing and jewelry rub against it.

If the dermatologist carries out a biopsy, they will usually remove the seborrheic keratosis at the same time.

There are several ways to remove seborrheic keratoses.

Cryosurgery

A doctor applies liquid nitrogen to the growth with a spray gun or cotton swab. The lesion freezes and falls off in a few days. A blister may form that will eventually dry into a crust and fall off.

However, the lesion can grow back, and changes in pigmentation can also occur.

How can cryosurgery treat a wart?

Skin shaving (shave excision)

A doctor shaves off the lesion with a scalpel without touching the layers beneath the skin’s surface. The collected cells can then go to a laboratory for a biopsy.

Electrocautery, curettage, or both

In electrocautery — also known as electrosurgery — the surgeon uses an electric current to burn (cauterize) the growth, under a local anesthetic. In curettage, a doctor uses a curette — a scoop-shaped surgical instrument — to scrape off the burnt growth.

A doctor will usually apply a local anesthetic to numb the area. On the face, however, they will use a lower current and will not numb the area.

Some people need only electrocautery, some need curettage, and others need both.

Laser therapy

The doctor uses a laser to remove the lesion.

Laser treatment can be ablative or nonablative. Ablative surgery removes the top layer of skin and heats the underlying layer to stimulate the growth of new collagen fibers. Nonablative surgery is less invasive and works by stimulating the growth of new collagen.

Topical treatments

Researchers are currently looking into options for topical applications to remove seborrheic keratoses.

The Food and Drug Administration (FDA) has approved a 40% hydrogen peroxide solution for raised keratoses that appears safe and effective. Minor adverse effects may occur, such as scaling, inflammation, and changes in skin color.

Chemical peels are also available. A doctor applies a peel containing trichloracetic acid to the lesion.

All these methods have disadvantages, such as:

• irritation and discomfort in the area during recovery time
• changes in pigmentation, where the skin becomes lighter or darker
• the need for several sessions, as a doctor may be unable to remove all lesions in one intervention.
• recurrence of growths or lesions continue to appear in other areas

There are no proven home remedies for seborrheic keratoses.

Lemon juice or vinegar can irritate the skin, possibly causing the lesion to dry and crumble. However, there is no evidence that this is safe or effective.

Some substances, such as tea tree oil, can trigger allergic contact dermatitis, an immune system reaction that causes itching and inflammation around the site.

Anyone with concerns about a lesion should see a doctor, who can check that it is not melanoma and advise on treatment, if appropriate.

Dermatologists are not certain why seborrheic keratoses develop.

Possible causes and risk factors include:

• Skin damage: Some types of seborrheic keratoses appear after dermatitis or sunburn.
• Genetic factors: Scientists believe a genetic mutation could be responsible when people develop a high number of seborrheic keratoses or when they run in families.
• Age: They are more common in those aged 50 years or above.
• Exposure to ultraviolet (UV) light: Similarities with solar lentigo suggest UV light may play a role.
• Medication: People who use epidermal growth factor receptor inhibitors to treat cancer may have a higher risk of warty growths.
• Skin friction: This may increase the risk and explain why they often appear in skin folds.

Seborrheic keratoses do not appear to be linked to any viral infection.

The authors of a 2016 research article note that seborrheic keratoses have “virtually no malignant potential.”

In rare cases, however, a sudden onset of numerous seborrheic keratoses may be linked to underlying malignancy, such as cancer in the gastrointestinal tract, lymphoma, or leukemia. In this case, it is known as Leser-Treélat sign.

Sudden eruptions of numerous seborrheic keratoses can also occur in pregnancy, during chemotherapy, and with various inflammatory skin disorders.

To diagnose seborrheic keratosis, a physician or dermatologist:

• will ask about symptoms and family and medical history
• will carry out a visual and physical examination
• may recommend a biopsy to rule out skin cancer and remove a growth at the same time
• may recommend further tests to rule out other conditions

A lesion with the features of seborrheic keratosis is unlikely to be skin cancer.

However, since it can be hard to distinguish between skin cancer and seborrheic keratoses, it is best to check with a doctor, especially if multiple lesions appear in a short time or if lesions change.

If the doctor suspects melanoma or is unsure, they may recommend a biopsy for examination under a microscope.

Seborrheic keratoses rarely become cancerous, but they share genetic features with some types of cancer. Researchers believe the gene process used by the lesions could help scientists learn more about certain types of cancer.

Here are some answers to questions people often ask about seborrheic keratoses.

How do you get rid of seborrheic keratoses?

In most cases, seborrheic keratoses do not need treatment, but a person may opt to remove them if they snag on clothing or feel unsightly. A doctor may remove one while taking a biopsy for skin cancer. Options include minor surgery, laser therapy, and cryotherapy. A doctor can advise on the best approach.

What do seborrheic keratoses look like?

Seborrheic keratoses can be skin-colored, tan, brown, yellow, gray, or very dark brown that may appear black. They can look waxy or rough, like a wart. Some are raised, as if stuck onto the skin, while others are flat. The size can range from a pinpoint to over 1 inch (around 2 millimeters to 3 centimeters) across. They usually grow slowly.

Are seborrheic keratoses serious?

Seborrheic keratoses are not cancerous but can share some features with malignant lesions. They can be hard to tell apart from skin cancer, so it is essential to see a doctor about any new or unexplained lesions.

Seborrheic keratoses are harmless lesions that appear on the skin, especially as people get older. They can occur anywhere on the body except the soles of the feet and palms of the hands.

They may be yellow, brown, tan, or skin-colored. Some look black but are, in fact, dark brown. They may be raised as if stuck onto the skin, but some are flat.

It can be hard to tell the difference between seborrheic keratoses and skin cancer. For this reason, a person should see a doctor if they notice a new lesion or if a lesion changes in any way.

Stimulation of hair growth on the head in women and men: effective procedures in CosmetoMed

#clinic_kosmetomed

Stimulation of hair growth is an important aspect of hair care, especially for those who experience hair loss or stunted growth. In this text, we will look at various procedures and methods that contribute to the stimulation of hair growth.

• Laser Hair Growth Stimulation: Laser therapy is one of the effective methods of hair growth stimulation. This is a safe and painless procedure in which laser radiation penetrates the scalp, stimulating blood circulation and providing sufficient nutrition to the hair follicles. It helps to accelerate the growth of new hair and strengthen existing ones.
• Mesotherapy: Mesotherapy is a procedure in which special preparations containing nutrients and vitamins are injected into the scalp. This improves the nutrition of the hair follicles and stimulates the growth of new hair.
