Syringocystadenoma papilliferum developing over hyperkeratosis of the nipple in a pregnant woman

A Case of Digital Papillary Carcinoma Arising on the Toe in a Young Female

Syringocystadenoma papilliferum is a rare benign adnexal hamartoma that is often associated with the nevus sebaceous of Jadassohn. It usually presents on the scalp and malignant transformation is rare. Here we present a case of digital papillary carcinoma on the toe of a teenage girl. The lesion recurred after two prior excisions without biopsy. The biopsy was read as a syringocystadenoma papilliferum with concerns for aggressive digital papillary adenocarcinoma, highlighting the importance of biopsy with excisions of neoplasms of unknown etiology.

Perineal papilliferous syringocystadenoma: An unusual localization

INTRODUCTION AND IMPORTANCE

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.

CASE PRESENTATION

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.

CLINICAL DISCUSSION

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.

CONCLUSION

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).
