[Nodular hepatic lesions secondary to myeloma IgA presenting as fever of unknown origin].

A 45 year old male presented with IgA multiple myeloma s/p (status post) autologous hematopoietic stem cell transplantation; and with a history of six weeks of fever and constitutional symptoms. Liver tests showed an infiltrative pattern, with ultrasound evidence of multiple nodular lesions. A laparoscopic biopsy identified circumscribed myeloma foci. This is the first reported case of myeloma nodular liver lesions causing a fever of unknown origin.
