Understanding Conjunctival Hypertrophic Scars: A Rare Post-Chalazion Surgery Complication

Conjunctival hypertrophic scars are an uncommon complication following ocular surgeries, particularly after chalazion removal. These scars can present as eyelid masses, causing significant discomfort and visual disturbances. This article explores a rare case of a conjunctival hypertrophic scar that developed after chalazion surgery, highlighting its clinical presentation, diagnosis, and management.

What is a Conjunctival Hypertrophic Scar?

A conjunctival hypertrophic scar is an excessive growth of fibrous tissue on the conjunctiva, the clear membrane covering the white part of the eye and the inner surface of the eyelids. Unlike normal healing, hypertrophic scars involve an overproduction of collagen, resulting in a raised, thickened area of tissue.

How Does It Develop After Chalazion Surgery?

While rare, hypertrophic scars can occur as a complication of chalazion surgery. Factors contributing to their development may include:

• Individual healing tendencies
• Surgical technique
• Post-operative care
• Underlying health conditions

Clinical Presentation: Recognizing the Signs and Symptoms

The case study presents a 74-year-old man who developed a conjunctival hypertrophic scar four months after chalazion surgery. His symptoms included:

• Severe ocular discomfort
• Excessive lacrimation (tearing)
• Itching of the upper eyelid

Physical Examination Findings

Upon examination, the following was observed:

• A 6 mm × 8 mm round, immobile, hard mass on the tarsal conjunctiva
• Mushroom-shaped protrusion
• No associated pigmentation, ulceration, or tenderness

Diagnostic Approach: Confirming Conjunctival Hypertrophic Scar

Diagnosing a conjunctival hypertrophic scar involves a combination of clinical examination and histopathological analysis. How is this condition definitively diagnosed?

Clinical Examination

A thorough ocular examination is crucial, including:

1. Visual inspection of the eyelid and conjunctiva
2. Assessment of the mass’s size, shape, and consistency
3. Evaluation of associated symptoms

Histopathological Analysis

Excisional biopsy and subsequent histopathological examination are essential for confirming the diagnosis. Key findings include:

• Thick interlacing collagenous fibrous bundles
• Fibroblastic proliferation
• Positive CD34 staining of spindle-shaped fibroblasts

• Inflammatory lesions

Key Distinguishing Features

Factors that help differentiate conjunctival hypertrophic scars include:

1. History of recent chalazion surgery
2. Characteristic appearance on clinical examination
3. Absence of typical features of malignancy (e.g., ulceration, pigmentation)
4. Histopathological findings consistent with hypertrophic scar tissue

Prevention Strategies: Minimizing Risk of Hypertrophic Scar Formation

While conjunctival hypertrophic scars are rare complications, there are strategies to potentially reduce their occurrence. What preventive measures can be implemented?

Surgical Technique Optimization

• Meticulous surgical planning
