Perineal papilliferous syringocystadenoma: An unusual localization.

Syringocystadenoma papiliferum (SCAP) is an infrequent, benign neoplasm originating from the apocrine or, less frequently, eccrine sweat glands. This condition predominantly manifests in regions such as the head, face, neck, and trunk. Notably, it is frequently associated with hamartomas of endocrine, sebaceous, or follicular origin, as well as with sebaceous nevi. In the context of this study, we present a clinical case involving a 65-year-old patient who exhibited an atypical anatomical presentation of syringocystadenoma papiliferum. This case highlights the importance of considering SCAP as a potential diagnosis of perineal cystic masses that need a surgical excision due to the risk of malignancy transformation. The uniqueness of the case under consideration lies in the rarity of syringocystadenoma papiliferum (SCAP), the atypical perineal localization, and its occurrence at an advanced age (65 years). • Papilliferous syringocystadenoma (SCAP) is a very rare entity. • Anoperineal localization of a SCAP is extremely rare. • Surgical excision is the mainstay treatment in SCAP due to the risk of malignant degeneration.
