title: [Giant cell sarcoma: a rare breast tumor].
abstract: This is a case report on a giant cell sarcoma or malignant osteoclastoma of the mammarian gland. Clinical diagnosis of this very rare tumor was of an exulcerating breast carcinoma. Histologically, this tumor shows epulis-like giant cells. Pathogenetically, a metaplasia of stromal cells, and of the glandular epithelium, is discussed. A simple mastectomy with extirpation of the axillary lymph nodes was performed. No metastases were found.
