title: Solitary extramedullary plasmacytoma of the colon, rectum and anus.
abstract: Solitary extramedullary plasmacytoma (SEP) is a neoplastic proliferation of a single clone of plasma cells that occur outside of the bone and bone marrow. It is rare, commonly occurring in the head and neck region, followed by the gastrointestinal tract. The aetiology, risk factors, natural history and consequent treatment are not well defined. We report an unusual case of SEP of the colon in an human immunodeficiency virus (HIV)-infected patient. The patient was managed with colonic resection and made an uneventful recovery. To our knowledge, this is the first reported case of extramedullary plasmacytoma of the colon and rectum in association with HIV infection.
