Abstract:
Multiple myeloma (MM) is a hematologic malignancy of plasma cell origin. Incidence of pleural effusion in multiple myeloma patients is approximately 6%. Myelomatous pleural effusions (MPE) are rare and occur in less than 1% of all MM cases. MPE is associated with advanced diseases, decreased survival time, and poor treatment response. In our case report, we describe a 59-year old man who presented with MPE at the initial diagnosis of MM. A diagnosis of MPE was reach through pleural fluid cytology and pleural tissue histology. The MPE had good response to initial dexamethasone without local therapy.
