We present a case of a 35-year-old woman with a yellow, verrucous, and itchy plaque on her scalp. Within this plaque, there was an erythematous, bleeding papule. Histopathologic findings were compatible with a diagnosis of syringocystadenoma papilliferum within a nevus sebaceous. We present a brief review of the natural history of nevus sebaceus, its pathogenesis, and management.
