Multiple myeloma (MM) is a malignant proliferation of a single clone of plasma cells and an excess of monoclonal immunoglobulin production. It is rarely associated with cutaneous and pleural involvement. We report a new case of a 62-year-old woman with a history of a symptomatic MM. Three months after chemotherapy initiation, she presented with subcutaneous nodules. Ultrasound-guided needle biopsy confirmed the diagnosis of cutaneous plasmacytomas. She underwent local radiation therapy leading to complete regression of subcutaneous nodules. One month later, she developed dyspnoea. Thoracic CT scan showed pleural thickening associated with pleural effusion. Pleural biopsy confirmed the diagnosis of pleural plasmacytoma. Chemotherapy including vincristine, doxorubicin and dexamethasone was administered. Cutaneous involvement and pleural effusion accompanying MM are uncommon. They are associated with poor prognosis.
