Primary Cutaneous Mucinous Carcinoma on the Scalp / 대한피부과학회지

ABSTRACT

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignant tumor believed to originate from the eccrine gland. It is important to exclude other possible origins of the mucinous carcinoma, such as the breast, lung, gastrointestinal tract, kidney, prostate, and ovary, because PCMC generally shows a better prognosis. Some histopathological clues are helpful to distinguish PCMC from metastatic mucinous carcinoma, but the final diagnosis should be made after a thorough systemic evaluation. We report a case of PCMC after a comprehensive evaluation to exclude metastatic mucinous carcinoma.
