FIBROEPITHELIAL LESIONS OF THE BREAST AT THE PATHOLOGY DEPARTMENT OF THE UNIVERSITY HOSPITAL CENTER OF JOSEPH RAVOAHANGY ANDRIANAVALONA MADAGASCAR

Abstract

Fibroepithelial tumours are a heterogeneous group of biphasic tumours comprising dual stromal and epithelial components. The two main types are fibroadenoma and phyllodes tumour. Fibroadenoma is the most common benign breast tumour. The aim of our study is to determine their epidemiological and anatomopathological characteristics. This is a retrospective, descriptive and analytic study of fibroepithelial breast tumors diagnosed at the Pathology Department of the University Hospital Center of Joseph Ravoahangy Andrianavalona Madagascar, from January 1, 2017, to December 31, 2021. We have collected, 157 cases, fibroepithelial tumors of the breast accounted for 18.76% of breast pathologies. The average age was 24.79 years, with extremes of 11 and 55 years. The sex ratio was 0.033. The main clinical sign was the presence of a nodule in 87.90% of cases. The majority of samples (61.79%) were excisional biopsies. Their average size was 3.98 cm, ranging from 1 to 26 cm. On macroscopic examination, a lobulated, fasciculated, nodular appearance was observed in 49.68% of cases. Fibroadenoma Not Otherwise Specified was the predominant histological type, accounting for 95.54% of cases. Fibroadenoma is the most common benign fibroepithelial tumor found in young women. Phyllodes tumors, on the other hand, are found exclusively in older women.
