[Phyllodes tumor. The experience of the 4th Obstetrics-Gynecology Department]

The experience of the IVth Obstretrics Gynecology Department. Between the 1st of January 1994 and the 1st of November 2001 587 operations have been performed as treatment of breast tumors in the IVth Obstetrics and Gynecology Department. The phyllodes tumor has been diagnosed in 11 cases (1.8% of the benign breast masses). The genesis is unknown. Local trauma, pregnancy, lactation, high estrogenic levels have been suggested to have an influence upon the tumoral development. The most common aspect is a round, hard, unpainful breast mass. The diameter is variable (1 to 45 cm). The mammogram shows a well defined, high density, smooth contour opacity. A four degree classification has been described. Specific evolution features may involve local recurrences and metastasis. The surgical treatment is mandatory but radiotherapy, chemotherapy and endocrine treatment protocols have been brought up.
