Objectives The objective of this study was to correlate clinical, radiological and pathological data of mammary microbiopsies

Methods This is a 20-month retrospective study from January 1, 2016 to Decembre 31, 2018 that included all patients who had a breast microbiopsies.

Results Out of 86 patients, one patient was excluded because the pathological examination was not contributory. The average age of the patients was 39 years (range, 20 to 71 years). We performed mammary microbiosis for ACR 4 in 82% of the patients. Pathological examination concluded that there was benign mastopathy, mainly fibrocystic dystrophy in 76% patients (a radio-histological discordance) and infiltrating ductal carcinoma in two patients. One patient had a breast microbiopsy for ACR 3 with familial breast cancer ATCDs. The anatomopathology concluded to the benignity of the lesions. All ACR 5 patients, (n =12), had infiltrating ductal carcinoma.

Conclusions Ultrasound guided mammary microbiopsy is a reliable examination that allows in most cases to determine the histological type of the mammary lesion when it is accessible to the biopsy, thus reducing the overall impact of the management of mastopathies. The problem arises when there is a radio-histological discordance, mainly in front of ACR4.
