title: Pulmonary and nodal multiple myeloma mimicking lymphoma.
abstract: Multiple myeloma is a haematological malignancy characterized by the occurrence of plasma cell tumours within the bone marrow. In advanced multiple myeloma, metastatic deposits outside the bone marrow (extramedullary) are rare. Reported extramedullary sites include the upper respiratory tract and lymph nodes. Parenchymal pulmonary plasmacytoma is exceptionally rare. We describe such a case in a 51-year-old male, who underwent allogenic marrow transplantation. 6 months post-transplantation developing nodal and hilar pulmonary multiple myeloma, the radiological appearances mimicking lymphoma.
