Radio-Histopathological Aspects of Breast Nodules in a Sub-Saharan African City (Ouagadougou, Burkina Faso)

Objective: To determine the diagnostic contribution of breast microbiopsy percutaneously under ultrasound guidance. Methodology: Retrospective descriptive study conducted from January 2014 to October 2017. The included patients had an ultrasound-guided breast microbiopsy after a mammographic and ultrasound scan. The variables collected were gender, age, nodule size, ACR classification and anatomopathologic diagnosis. Results: 347 nodules were explored in 313 patients. There were 300 women (95.85%) and 13 men (4.15%), a gender ratio of 23.07. The average age was 44.64 ± 14.18 years. The average size of the nodules was 30.33 ± 19.58 mm. There were 53.89% ACR4 grade nodules, 48% ACR5 nodules and 32.28% ACR3 nodules. 86.49% of ACR3 nodules were benign and 97.92% of ACR5 nodules were actually malignant. Malignant tumors accounted for 50.29% of the nodules and were dominated by invasive breast carcinomas in 98.26%. The average age of patients with malignant tumors was 49.15 ± 11.55 years. 16% of patients with malignancy were aged under 40 years old. Conclusion: The diagnostic yield was satisfactory and there was a good correlation between the rate of malignant and benign lesions and the positive predictive values of malignancy in the literature.
