Primary Cutaneous Secretory Carcinoma: A Case Report and Literature Review

Cutaneous secretory carcinomas (CSCs) are primary neoplasms of the skin that have been just recently described in the literature through case reports and series.In this case, a cutaneous lesion was found on the left temporal region of an 83-year-old male.He was referred to plastic surgery for complete excision, with negative margins confirmed by pathology.Histology, immunostaining, and genetic testing showed characteristics confirming the diagnosis of CSC and were supported by the information present in the current literature.Our patient showed no evidence of nodal disease or recurrence during regular follow-ups.Given the rarity of CSCs, we aim to present our experience regarding the diagnosis, pathological analysis, and management of our patient as well as summarize the present literature to further open avenues of research.
