Abstract:
Pilomatricoma is a benign tumor derived from the hair matrix. Pilomatricoma-like changes have been described in epidermal cysts in Gardner's syndrome. Apart from this association, a cyst can arise from various portions of a hair follicle, and combine to form a hybrid cyst. Follicular hybrid cyst is an interesting pathologic phenomenon, and needs to be explained for their pathogenesis. We present a case in which a pilomatricoma was situated in the immediate vicinity of an epidermal cyst. Histopathologic findings showed that one part of the cyst had a feature of an epidermal cyst, and the other part had a feature of a pilomatricoma.
