Pigmented conjunctival squamous cell carcinoma simulating a conjunctival melanoma.

Abstract

PURPOSE:

To report a pigmented conjunctival squamous cell carcinoma that clinically simulated a conjunctival melanoma.

DESIGN:

Interventional case report.

METHODS:

Ocular examination, surgical excision, and clinicopathologic correlation.

RESULTS:

A 78-year-old white man developed a lightly pigmented mass at the temporal limbus of his right eye. The differential diagnosis included pigmented squamous cell carcinoma and malignant melanoma. Histopathologic examination revealed a malignant squamous cell tumor that contained foci of melanin pigment. The final diagnosis was pigmented conjunctival squamous cell carcinoma.

CONCLUSION:

Conjunctival squamous cell carcinoma may rarely be pigmented and simulate a conjunctival melanoma.
