A Case of Primary Cutaneous Mucoepidermoid Carcinoma Developed on the Scrotum / 대한피부과학회지

ABSTRACT

Mucin producing squamous cell carcinoma (mucoepidermoid carcinoma) is a carcinoma showing squamous and adenomatous differentiation. It is more aggressive than the usual carcinoma of the skin and it must to be evaluated and treated more carefully. We report herein a case of mucoepidermoid carcinoma associated with previous multiple skin cancer. The patient, a 56-year-old male with prior arsenical exposure, presented with a itching irregular marginated ulcer on the left scrotum and other scaly macular erytheinatous skin lesions on the left shoulder and lower back. The histopathological findings from the scrotal lesion showed multiple foci of mucin deposition throughout the squamous cell carcinoma. Special mucin and CEA immunohistochemical staining revealed the epithelial nature of mucin and its glandular structure. We diagnosed this scrotal lesion as mucoepidermoid carcinolna, and it was totally removed by surgical excision.
