Pilomatrixoma. An unusual case with secondary corneal ulcer.
A 51-year-old man presented with a three-month history of a red and painful right eye. A corneal ulcer was diagnosed, and laboratory workup failed to disclose an etiologic factor. A white tumor, with an irregular and calcified surface, found in the superior tarsal conjunctiva, was considered to be the cause of the corneal ulcer. The tumor proved to be a pilomatrixoma that presumably developed from a congenitally ectopic hair follicle.
