Fibrous histiocytoma of the corneoscleral limbus.

A 21-year-old white woman had an apparently benign fibrous histiocytoma at the corneoscleral limbus. By histopathologic and ultrastructural studies, the tumor consisted of lipid-containing histiocytes and fibrocytic cells arranged in a storiform configuration with a collagenous interstitium. After an excision, the lesion gradually decreased in size and did not recur in a five-month follow-up period.
