ABSTRACT: 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.
