Syringocystadenoma Papilliferum: A Case Report and Review of the Literature

Syringocystadenoma papilliferum is a very rare, benign adnexal tumor that originates from the apocrine sweat glands. Herein, we report a 25-year-old male who presented with a 10-year history of an asymptomatic slowly growing skin lesion on his face. Skin examination revealed a solitary rounded 3 × 3 cm erythematous plaque with central crustation on the right side of his face. Punch skin biopsy was taken from the lesion. The epidermis showed downward papillomatous extensions. The dermis showed multiple epithelial sheets and dilated ducts that were lined by columnar cells. On the basis of the above clinicopathological findings, the diagnosis of syringocystadenoma papilliferum was made. The patient was reassured and referred to a surgeon for surgical excision of the lesion
