ULCERATED SYRINGOCYSTADENOMA PAPILLIFERUM OF THE SCALP IN AN ADULT WOMAN: A CLINICAL AND DERMOSCOPIC DESCRIPTION OF A DE NOVO CASE

Syringocystadenoma papilliferum (SCAP) is a rare benign adnexal tumor of apocrine or eccrine origin, typically presenting at birth or during early childhood. It most commonly occurs on the scalp or face, frequently arising in association with a sebaceous nevus. We report a rare case of an ulcerated, rapidly enlarging syringocystadenoma papilliferum occurring de novo on the temporal scalp of a 45-year-old woman without any pre-existing lesion. Complete excisional biopsy was performed, and no recurrence was observed after six months of follow-up. This case underscores the importance of accurate clinical evaluation and histopathologic assessment in distinguishing benign adnexal tumors from malignant mimickers.
