title: Pancoast's syndrome in multiple myeloma.
abstract: A 74-year-old patient developed IgG multiple myeloma. 7 months later a right Pancoast's syndrome was observed. Computerized tomography established the extrapleural origin of the tumor. Fine needle aspiration revealed pathological plasma cells. Partial reduction of plasmacytoma was noted following radiotherapy, but the patient succumbed to pneumonia. Autopsy confirmed that a plasmacytoma caused the Pancoast's syndrome. The importance of early diagnosis and accurate therapy of this rare manifestation of multiple myeloma is discussed.
