A Case of Pigmented Follicular Cyst / 대한피부과학회지

ABSTRACT

Pigmented follicular cyst is a rare disorder which typically presents as a pigmented papule on the head or neck. Histologically, it exhibits terminally differentiated, pigmented hair shafts in an epidermoid cyst. It was described as a variant of epidermal cyst originating from the infundibular epidermis of pilosebaceous unit. We report a case of pigmented follicular cyst on the occipital scalp in a 7-year-old girl with typical histologic features.
