A case of multiple myeloma diagnosed during the treatment of refractory cellulitis

Abstract

Patients with multiple myeloma are vulnerable to infection, although cellulitis is rare as complication of multiple myeloma. In our case of a 56-year-old man, refractory cellulitis led us to investigate immunosuppressive factors, and we found that he was suffering from multiple myeloma. As our case, unusual skin lesions suggest comorbid immunosuppressive disease such as malignancy. We need close investigation of complications in patients with atypical skin lesions.
