Three cases of lymphangiectatic pilomatricoma

초록

Pilomatricoma is a benign adnexal tumor, differentiating towards elements of the hair matrix and shaft. The tumor typically presents as a solitary, deep-seated, firm nodule with overlying normal epidermis. Herein, we report three cases of pilomatricomas with the dermal bullae overlying tumors. Histopathological examination of the lesions showed marked lymphatic dilatations, edema, and attenuated collagen and elastic fibers above the pilomatricomas in the upper dermis. We diagnosed them as lymphangiectatic pilomatricomas.
