A Case of Multiple Cylindromas / 대한피부과학회지

Cylindroma is an adnexal tumor which is mostly observed on the scalp. It usually occurs as a solitary lesion rather than multiple lesions. Histopathologically, the tumor is composed of numerous islands of basaloid cells which fit together like pieces of a jigsaw puzzle with surrounding hyaline sheaths. In Korea, there have been two reports of solitary cylindroma in the dermatologic literature, but no report of multiple cylindromas. We herein report a case of multiple cylindromas. A 34-year-old woman presented with three erythematous papules on her scalp, which developed four to five years before. Histopathologic findings on all papules revealed the typical appearance of cylindroma.
