Distal Tibia and Foot Involvement in a Patient With Waldenstrom's Macroglobulinemia.

ABSTRACT

Bone lesions are a rare presentation in Waldenstrom's macroglobulinemia patients. Although lytic bone lesions and generalized osteoporosis have been described variably in literature on Waldenstrom's macroglobulinemia patients, distal long bone and foot involvement has not been described to our knowledge. We report a patient with Waldenstrom's macroglobulinemia with IgM monoclonal spike, plasmacytic infiltration of bone marrow, and symptoms of foot pain, and found to have distal tibia and foot involvement. The symptoms of bone lesions in our patient were significantly improved with radiation treatment. The possibility of distal involvement of long bones in a clinically relevant presentation should be kept in mind in these patients.
