Abstract

Extraosseous manifestations are found in less than 5% of patients with multiple myeloma. They can arise in any tissue, and their presence has been associated with more aggressive disease. We present FDG PET/CT findings of immunoglobulin A κ multiple myeloma with innumerable hypermetabolic right lower extremity lesions of cutaneous and subcutaneous involvement of plasmablastic plasma cell myeloma in a 44-year-old man.
