Introduction/Background Phyllodes tumors of the breast are rare, constituting 0.3 to 0.9% of breast tumors, characterized by the dual conjunctival and epithelial components. They can be benign or malignant. they are classified into 3 grades, sarcoma is their malignant form, it is present in 2.1/1 million women.

The interest of this study is to highlight the epidemiological, clinical, therapeutic, prognostic and progressive characteristics of phyllodes tumors of the breast.

Methodology We included all patients admitted to us for treatment of phyllodes tumors over a period spanning 5 years the inclusion criteria were complete files.

Any patient without a complete file or follow-up was excluded from our study.

Results The average age of our patients was 35.5 years, with a range of 13 to 58 years.

A history of fibroadenoma was found in a patient the consultation period was 12 months with extremes of 1 to 4 years the average tumor size was 6 cm with extremes of 1.5 to 23 cm the histological type was benign in 72% of cases, malignant in 7% of cases, and intermediate or borderline in 11% of cases.

19% of operated patients had unsatisfactory margins with recovery of the tumor bed a patient was referred for radiotherapy after a 3-year follow-up for our patients, we did not note any recurrence or metastatic development.

Conclusion Phyllodes tumors are rare fibro-epithelial tumors it is a subject of controversy in terms of terminology, classification and treatment the diagnosis is primarily histological morphological classification does not make it possible to predict the evolution the basis of treatment is surgery, radiotherapy is reserved for malignant and large phyllodes tumors chemotherapy seems to have an ill-defined place the prognosis is based on the histological characteristics of the connective tissue component of these tumors.
