title: A new sarcomatoid variant of multiple myeloma in a 20-year-old male.
abstract: We present a 20-year-old man with a rare variant of multiple myeloma with peculiar spindle cell morphology and sarcomatoid growth. The diagnosis of multiple myeloma was substantiated by clinical examinations. The patient was treated with several therapeutic trials including autologous stem cell support. Unfortunately, he developed a disseminated aspergillosis of the lungs and died of fatal lung bleeding. We recommended that "sarcomatous" multiple myeloma be considered in cases of "unclassifiable" sarcomatous tumors of the bone marrow.
