Primary cutaneous cribriform carcinoma of the neck: a case report

Primary cutaneous cribriform carcinoma is an unusual apocrine tumour that mainly occurs on the limbs of middle-aged females. We herein report a case of a 32-year-old woman who underwent surgical excision of a nodular lesion on her neck that had been present for 10 months. Histopathology showed a dermal tumour composed of interconnected aggregations of neoplastic cells and round spaces of various size and shape, resulting in a cribriform pattern. A diagnosis of cutaneous cribriform carcinoma was made. No peripheral lymphadenopathy was evident, and investigations for internal malignancies gave negative results. The patient was tumour-free 2 years after surgery. Although primary cutaneous cribriform carcinomas have up to now shown an indolent course, the number of reported cases is too limited for definitive prognostic conclusions. Therefore, surgical excision with clear margins and adequate follow-up are recommended.
