Axillary primary mucin producing epithelial malignancy - rarely encountered site

The most common skin malignancy in the axilla is Basal cell carcinoma. Primary mucin producing epithelial carcinoma in the axilla can closely resemble metastatic mucinous carcinoma, most often originating from the breast, but also from the gastrointestinal tract, lung or ovary. Axilla is a rare site for primary mucin-producing epithelial carcinoma of skin. Thorough clinical examination histopathological examination with IHC and other ancillary investigations are necessary to confirm the diagnosis and to rule out metastatic mucinous carcinoma. We present a rare case of primary mucin producing epithelial carcinoma of axillary skin in an elderly male patient which was present since two and half year, without any complication. Which was diagnosed by histopathological examination, complete clinical examination and radiological examination and confirmed with IHC marker. Which presented to us as a lesion mimicking benign cyst. Which was managed by wide local excision of the lesion and lymph node dissection till level II.
