Cystosarcoma phyllodes. Diagnosis and management

Abstract

The diagnosis and management of cystosarcoma phyllodes is analyzed by reviewing the literature and presenting cases from our institution. This rare neoplasm of the female breast represents less than 1% of all breast tumors. Most patients present in the fourth and fifth decades of life. The predominant complaint is a palpable mass in the breast. Systemic manifestations occur after metastases have developed. Treatment is surgical excision. There is some controversy, however, over which type of surgical procedure should be performed. We recommend total mastectomy. Local recurrence and metastases do occur and have been related to inadequate surgery and various histological characteristics (mitotic activity, tumor margin, and stromal cellular atypia).
