Cystosarcoma phylloides in adolescent female patients.
Nine cases of cystosarcoma phylloides in adolescent female patients are reported along with an additional 35 cases collected from the literature. Analysis of these 44 cases revealed 37 (84.1 percent) benign lesions, 6 (13.6 percent) malignant tumors, and 1 borderline lesion. Excision was the most common operative procedure and was performed in 35 patients. Nine patients underwent mastectomy. There were three recurrent lesions (one benign and two malignant) for a recurrence rate of 6.8 percent. Wide excision was successful in the treatment of recurrent lesions. On the basis of these data, excision is the preferred initial therapy of cystosarcoma phylloides in the adolescent patient regardless of the histologic classification of the lesion. Malignant cystosarcoma is more likely to recur than a benign lesion but a recurrence can be managed with reexcision. Sacrifice of the adolescent breast at the initial procedure is strongly discouraged.
