title: Syringocystadenoma papilliferum of the eyelid.
abstract: Syringocystadenoma papilliferum is a benign adnexal tumor of the scalp and face. We treated syringocystadenoma papilliferum in a 31-year-old man who had a circumscribed cup-shaped lesion of the left upper eyelid with a central crater. On histologic examination, the epidermal edge showed hyperkeratosis and invasive acanthosis with papillary projections that filled the central crater. The deeper portions of the projections resembled ductal structures lined by an inner columnar epithelium, which demonstrated luminal apical decapitation secretions, and an outer layer of smaller cuboidal cells. The fibrovascular dermal tissue exhibited prominent plasmacytic infiltration underlying the papillary epithelium. Although rare, syringocystadenoma papilliferum should be considered in the differential diagnosis of umbilicated squamous or basal cell tumors, especially if noted in a young individual.
