Abstract

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignant adnexal tumor of eccrine origin with a higher incidence in the head and neck region of the body while scrotal skin involvement is rare. We report a case of a 72-year-old man with ulceration of painless scrotal lesions of 10 years' duration. Histology of the wedge biopsies of the lesions was mucinous carcinoma. Clinical workup excluded noncutaneous primary sites of mucinous carcinoma and distant metastasis. He had wide excision of the scrotal skin lesions with histological findings of nests of malignant cells separated from pool of mucin by fibrocollagenous septae. Periodic acid-Schiff stain was positive; however, immunohistochemical stains for estrogen and progesterone receptors were negative. No local recurrence was observed after 12 months of follow-up. Scrotal PCMC is a rare tumor; this may probably be the first reported case of this tumor in the scrotum. Prognosis was good following surgical excision.
