Plasma cell tumors are a diverse group of neoplasms characterized by monoclonal proliferation of plasma cells. Extramedullary plasmacytoma (EMP) is a rare form of localized plasma cell tumor that arises most often in the head and neck region. We present an unusual case of EMP of the palatine tonsil from a tertiary care university hospital. We discuss the histopathologic and radiologic evaluatio...
Less than 5% of patients with a plasma cell dyscrasia present with a single bone (SBP) or extramedullary plasmacytoma (EMP) without evidence of systemic disease (normocalcemia, absence of anemia, preservation of uninvolved immunoglobulins, or renal disease attributable to myeloma). Diagnosis requires biopsy confirmation of a monoclonal plasma cell infiltrate from a single site. The treatment of...

Most lesions occur in the head and neck, but primary tracheal lesions are very rare. Patient Concerns: In this report, we describe a case of tracheal EMP discovered in a 48-year-old man who presented with a history of progressive dyspnea. Diagnoses: Comp...
