title: A case of spindle cell carcinoma of the breast--long survival achieved by multiple surgical treatment.
abstract: Spindle cell carcinoma of the breast was formerly called carcinosarcoma, and is relatively rare. We report a case of spindle cell carcinoma of the breast. The patient was treated with multiple surgeries and achieved long-term survival. The patient was a 52-year-old woman, in whom small induration developed at the areola of the nipple of the right breast. The lesion was resected, and benign tumor was diagnosed pathologically. Four years later, she had recurrence at the scar, and a typical mastectomy was performed. A tumor developed again 5 years later; the lesional focus was at the scar of the right chest wall and invasion of the ribs and the sternum was noted. The sternum and the right costal cartilage of ribs 3-9 were dissected together. The right chest wall was reconstructed and adjuvant radiation therapy performed. Four years after this operation, tumor recurred near the scar and chest wall resection including part of the pericardial cavity and the left lung was performed. However, 6 months later, invasion of the mediastinum, heart and lung were noted. The patient died 16 years after the first surgery. Dermatofibrosarcoma protuberance of the breast was diagnosed at the second operation. However, the diagnosis was changed to spindle cell carcinoma of the breast following immunohistochemical studies. Spindle cell carcinoma of the breast is rare, and definitive histopathological diagnosis is often difficult. When spindle cell carcinoma is suspected, comprehensive diagnostic studies including immunohistochemical examinations should be performed. Even in case with multiple recurrences correctly performed operations may contribute to prolongation of survival.
