Giant Ulcerative Solitary Plasmacytoma of the Sternum: Resection with Reconstruction in a Resource-Limited Setting.

Solitary plasmacytoma of the sternum is a rare plasma cell neoplasm, challenging to manage in resource-limited settings. We present a 48-year-old man with a recurrent, ulcerated anterior chest wall mass. Imaging showed a destructive sternal lesion, confirmed as solitary bone plasmacytoma via histopathology. Radical excision and chest wall reconstruction using pectoralis major flaps and improvised wiring were performed. Postoperative wound infection occurred. At 6 months, recovery was favorable, with adjuvant radiotherapy planned. This case highlights diagnostic and reconstructive challenges and demonstrates feasible management in a low-resource setting.
