The table shows details offive patients with sarcoidosis seen by us during 1%986. In each case the diagnosis ofsarcoidosis was based on both the clinical findings and histological evidence ofnon-caseating epithelioid cell granulomas. The mean age of the patients at the time of diagnosis was 55 (range 42-65). In four patients myeloma developed several years after the diagnosis of sarcoidosis; in one both diagnoses were made at the same time. The duration ofsarcoidosis was more than two years in three patients (cases 1, 2, and 4), and sarcoidosis was considered to be active at the time of diagnosis of myeloma in two (cases 2 and 5). Two patients (cases 1 and 2) had been treated with steroids. All patients met the diagnostic criteria for multiple myeloma. Four patients (cases 1-4) were treated with cytotoxic drugs and the other (case 5) was followed up without treatment. Four patients survived, but the other (case 3) died in 1985, four years after the diagnosis ofmyeloma.
