Phyllode tumors of the breast are fibroepithelial tumors similar to fibroadenomas but with a predominant conjunctive tissue component. The aim of this work was to determine the specific diagnostic, therapeutic and prognostic features of this tumor. A retrospective series of 41 cases was collected in the gynecology-obstetrics ward from 1980 to 1991. The analysis of this series showed the following characteristics: incidence of phyllode tumors was 0.46% of all breast tumors. Mean age at diagnosis was 30 years, in 75.6% of the women were in a period of reproductive activity. Mean delay between the first clinical signs and diagnosis was 20 months. Mean size was 12 cm Diagnosis was confirmed at pathology examination in all cases. The tumor was classed grade 1 and 2 in 65.9% of the cases, grade 3 in 9.8%, grade 4 in 17.1%. Surgical treatment alone was used in all cases with large tumorectomy (48%), simple mastectomy (30%), and total mastectomy with node dissection (22%). After a follow-up of 1 to 7 years, there were 3 deaths and 11 local recurrences requiring reoperation. In the remaining cases, the outcome was favorable without recurrence or metastasis. These results together with those reported in the literature show that histological confirmation is required for the diagnosis of phyllode tumors. Surgical treatment alone is required with wide exeresis because of the voluminous tumor formation the age of the patient and the histological grade. Finally, prognosis depends on the histological characteristics of the conjunctive tissue component of the tumors.
