title: Plasmacytoma of larynx--a case report.
abstract: Plasma cell myeloma, the most common plasma cell neoplasm, is characterized by the presence of multiple lesions in the bone marrow. A single isolated lesion may occur either in bone (solitary plasmacytoma of bone) or in soft tissue (extramedullary plasmacytoma). Most cases of extramedullary plasmacytoma occur in the head and neck region. The diagnosis is established by histopathology and immunohistochemistry. A detailed evaluation for lesions at other sites is recommended as extramedullary plasmacytoma treated by radiation therapy has better survival rates than plasma cell myeloma, which is treated by chemotherapy. A case of plasmacytoma of the larynx is presented highlighting clinical and histological features with a review of literature.
