[Plasmacytoma of chest wall].

We report a 70-year-old man who suffered from right anterior chest wall tumor. Physical examination revealed an elastic hard mass at the right 4th rib measured 6 cm in diameter. Chest X-ray and computed tomography (CT) revealed enhanced mass and destruction of the 4th rib. As needle aspiration cytology did not define the diagnosis, we performed a chest wall resection and reconstruction. Histological diagnosis of the tumor was plasmacytoma (IgG lambda type). Five months after the operation, the tumor recurred at the right anterior chest wall. Radiotherapy was performed with dose of 50 Gy. Fourteen months after the operation, the tumor recurred at the lower sternum, and the chemotherapy was performed using ranimustine, vincristine, melpharan and dexamethasone. He is doing well 2 years and 9 months after surgery without signs of progressive disease or conversion to myeloma
