Rare Pedal Manifestation of Diffuse Multiple Myeloma Lesions.

Multiple myeloma is a malignancy of plasma cell proliferation leading to production of monoclonal immunoglobins. Among the classic features of multiple myeloma are bone lesions, which typically manifest in the axial skeleton, vertebrae, pelvis, skull, ribs, and proximal extremities. The several types of multiple myeloma include symptomatic multiple myeloma, monoclonal gammopathy of undetermined significance, smoldering/indolent myeloma, and solitary plasmacytoma of bone.
