A Rare Case of Male Breast Plasmacytoma - Abstract
A plasmacytoma is a discrete, solitary mass of neoplastic monoclonal plasma cells in either bone or soft tissue (extramedullary). Breast plasmacytomas, in particular, are extremely rare and can present as a primary isolated tumor or as an extramedullary manifestation of multiple myeloma (MM). Microscopically, immature plasmacytomas may mimic other neoplasms, so caution should be made on histological examination to ensure the correct diagnosis and corresponding therapy. We present a case of 57 year old male, who was a known case of multiple myeloma and on regular medication for the same, presented with complaints of swelling of right breast. Excision of the lump was done and histopathological examination was suggestive of plasmacytoma.
