title: Multiple myeloma in a patient with systemic lupus erythematosus, myasthenia gravis and non-familial diffuse palmoplantar keratoderma.
abstract: The coexistence of autoimmune diseases and malignancies including lymphoproliferative diseases is often reported in the literature. Here we report an unusual case with two autoimmune diseases--myasthenia gravis (MG) and systemic lupus erythematosus (SLE) associated with unique palmoplantar keratoderma (PK) which preceded the development of multiple myeloma (MM) for twenty and seven years respectively. MG associated with non-malignant thymoma developed in 1981 and was successfully treated with thymectomy and physostigmine. Thirteen years later SLE was diagnosed and until now it is also accompanied by skin lesions corresponding to non-familial, diffuse palmoplantar keratoderma which is resistant to treatment. In 2001 the patient revealed inguinal and abdominal lymphadenopathy first diagnosed as extramedullary plasmacytoma and then as multiple myeloma on the basis of bone marrow infiltration and monoclonal gammopathy. Therapy with VAD regimen achieved complete remission of the MM and significant improvement of the skin changes lasting for six months. We failed to collect sufficient numbers of CD 34+ cells for peripheral blood stem cell transplantation. Now the malignancy is in partial remission after CHOP therapy and the skin lesions have returned to their initial status. To our knowledge, this is the first case to be reported with coexistence of these four diseases.
