Myelomatous pleural effusion.

ABSTRACT

Serous effusions in multiple myeloma are uncommon but a myelomatous pleural effusion occurring in these patients is extremely rare. Here we report a rare case of a 38 years lady who was diagnosed to have multiple myeloma and subsequently developed pleural effusion. The myelomatous nature of the effusion was first diagnosed on cytology and subsequently confirmed by a pleural biopsy. The pleural effusion showed an initial response to chemotherapy but subsequently recurred.
