MD, PhDAmerican Journal of Dermatopathology: April 2014 - Volume 36 - Issue 4 - p 348–352 doi: 10.1097/DAD.0b013e3182a38bb9 Extraordinary Case Report Abstract Author Information Abstract Abstract: Syringocystadenocarcinoma papilliferum (SCACP) is an extremely rare cutaneous neoplasm with apocrine differentiation. Only 27 cases have been reported up-to-date, 8 of them described as carcinomas in situ. Two cases with local recurrence and 3 cases with regional lymph node metastases have been documented. The authors present the case of a 32-year-old female with a SCACP in situ on the scalp that recurred 8 years after the excision of the primary tumor. No SCACP with late recurrence have been previously reported. This case highlights the need for a long-term follow-up in patients with this type of carcinoma.
