Scleroderma-like Initial Presentation of Multiple Myeloma.

Systemic sclerosis (SSc) is a multisystem connective tissue disease affecting skin and internal organs. Certain drugs, environmental toxins and some viruses have been implicated in SSc-like illnesses. Scleroderma may be associated with some connective tissue disorders or autoimmune diseases but coexistence of scleroderma with multiple myeloma (MM) is an unusual finding. We here report a case of a 59 years old female patient with 5 months history of progressive thickening of skin all over the body. Multiple myeloma was diagnosed by osteolytic lesion in skull X-ray, increase in clonal plasma cells by bone marrow biopsy, very high Kappa light chain in serum light chain assay and detection of M band by serum protein electrophoresis.
