Epidemiological, Clinical and Histological Characteristics of Phyllodes Tumors in the Gynecology Department of the Donka National Hospital of the CHU of Conakry (Guinea)

Introduction: The objectives of this study were to determine the frequency of phyllodes tumors of the breast, to describe the epidemiological, clinical and histological characteristics of phyllodes tumors of the breast in the gynecology department of the Donka National Hospital. Methods: This was a retrospective descriptive study lasting 5 years, from January 1, 2018 to December 31, 2022, in the gynecology department of the Donka National Hospital, covering the records of patients whose diagnosis of phyllodes tumors of the breast was confirmed by histology. Results: The frequency of phyllodes breast tumors was 2.7% out of 807 benign and malignant breast pathologies. The epidemiological profile was that of women in the 30 - 39 age bracket (41.0%), nulliparous (50.0%) and genitally active (91%). Breast swelling was the main reason for consultation (81.9%). The left breast was the most affected (54.6%). Tumor size was between 2 - 4 cm in 63.7% of patients and ≥ 5 cm in 6 patients (27.2%). The tumor was classified on histology as grade I and grade II with frequencies of 54.6% and 27.2% respectively. Benign phyllodes tumors confirmed by histology were the most numerous (81.8%). Conclusion: Phyllodes tumors of the breast were uncommon in our department. They mainly affect young, nulliparous women. Diagnosis is histological, with a very high frequency of benign tumors.
