An Uncommon Case of Atypical Fibroxanthoma of the Bulbar Conjunctiva

Abstract

An Atypical Fibroxanthoma (AFX) is a benign skin tumor of mesenchymal origin most commonly found on the sun-exposed or radiation-damaged skin of the elderly. AFX may share many common histologic and clinical characteristics with squamous cell carcinoma and melanoma; however, it is a benign process. Therefore, differentiating between these lesions is important. Differences in histologic features and patterns of immunohistochemical staining for CD68, CD10, cytokeratins, S-100 and Fi-67 may diagnose AFX. The presence of an AFX on the conjunctiva is rare with only five other reported cases. We report a case of AFX that developed in the bulbar conjunctiva near the limbus.
