Infarcted Tarsal Pyogenic Granuloma Simulating Malignant Melanoma

Area of Science:

• Ophthalmology
• Dermatopathology

Background:

• Pyogenic granulomas can occur in various locations, including the conjunctiva.
• Rapidly enlarging lesions require prompt diagnosis to rule out malignancy.

Observation:

• A 34-year-old male presented with a rapidly enlarging, pedunculated brown lesion on the tarsal conjunctiva.
• The patient had a history of recurrent chalazia.

Findings:

• Histopathologic analysis of the excised lesion revealed features consistent with a necrotic pyogenic granuloma.
• The lesion's appearance and rapid growth mimicked other more serious conditions.

Implications:

• This case highlights the importance of considering pyogenic granuloma in the differential diagnosis of conjunctival tumors.
• Accurate histopathologic examination is crucial for distinguishing benign lesions from malignant ones like conjunctival malignant melanoma.
