Extramedullary plasmacytoma (EMP) is an uncommon entity that most commonly involves nasopharynx and upper repository tract. Involvement of GIT occurs in approximate 10% of cases. According to WHO plasma cell tumors have been classified into two main groups: Multiple myeloma and plasmacytoma. Plasmacytoma includes solitary plasmacytoma of bone and solitary extramedullary plasmacytoma. EMP can be...

Extramedullary plasmacytoma is a rare neoplasm characterized by monoclonal proliferation of plasma cells and accounts for about 3 - 5% all cell neoplasms including bone extramedullary tumors. Plasmacytomas are more predominant in males who the 5th – 6th decade. It most often located head neck region. usually affects upper respiratory tract 80% cases 15% spread to cervical lymph nodes. They pres...

Extramedullary plasmocytoma occurs in the nasal cavity relatively rarely. Basing upon the case of a 59-year old woman, the authors discuss the difficulties of diagnostic treatment and the course of the disease.

Plasmacytomas are extramedullary accumulations of plasma cells originating from soft tissue. Mediastinal plasmacytoma is a rare presentation. A 67-year-old man recovered after antibiotic treatment for community-acquired pneumonia. However, on convalescent chest radiography after 3 months, mass like lesion at the right lower lung field was newly detected. Follow-up chest computed tomography (CT)...

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 a...

A 56-year-old woman was referred to our hospital with a growing gastric submucosal tumor. An upper endoscopic examination revealed two gastric tumors, an original polypoid tumor and a newly diagnosed superficial tumor. Boring biopsied specimens of the submucosal tumor showed gastric plasmacytoma; however, the other specimens showed no malignancy. Blood diseases were ruled out using various exam...

plastic proliferation of plasma cells arising from non-osseous sites, while the neoplastic plasma cells in multiple myeloma patients usually involve the medullary space of bones. Extramedullary plasmacytoma may be primary or secondary to marrow involvement by myeloma. Extramedullary plasmacytoma arising from the mediastinum is known to be extremely rare (1). Herein, we present a rare case of me...
