Primary mucinous eccrine carcinoma of axillary skin: Report of a rare case

Abstract

Primary mucinous eccrine carcinoma is a rare low-grade malignancy of sweat gland. Axilla is an uncommon site of this tumor. Primary mucinous carcinoma mimics metastatic mucinous carcinoma from breast, gastrointestinal tract, lung, and ovary. Histopathology with immunohistochemistry and other ancillary investigations are necessary to confirm the diagnosis and to exclude metastatic mucinous carcinoma. We present a rare case of primary mucinous carcinoma of axillary skin in an elderly male patient, diagnosed by histopathology and immunohistochemistry.
