We present a case of ductul eccrine carcinoma in a 70 year old female. She presented with nodular painless lump in right axilla from 2 months. The lump was aspirated and cytological diagnosis of primary adenocarcinoma was made. The histopathology made up the final diagnosis and special stains confirmed it.
