Syringocystadenoma papilliferum as a cutaneous mass in an unusual location. A case report

Syringocystadenoma papilliferum [SP] is an uncommon adnexal adenoma, most often located on head and neck. We described an unusual appendage tumour, most importantly appearing at later age with vulvar location adjacent to the labio-femoral sulcus situated in the cutaneous tissue and having rapid growing pattern. Different prominent Ig class was found in the secretory component of the tumour epithelial cells and in the plasma cells underlying the tumour epithelium. A diagnosis of SP was made by characterizing histopathologic features of the biopsy specimen
