Purpose: to evaluate, in a prospective way, the importance of ultrasound features of solid breast lesions in the differentiation between benign and malignant lumps. Methods: one hundred and forty-two patients with solid breast lesions, from the Department of Gynecology and Obstetrics of the Federal University of Goias (Brazil), were included in the trial. All ultrasound examinations were performed by a training doctor, always supervised by an experienced professional. The characteristics of the lesions studied were: shape, retrotumoral echoes, internal echoes, oriented diameter, halo of bright echoes and Cooper ligaments. Each of the ultrasound features was compared to the results of the histological examination. Results: among the 142 patients included in the trial, 90 (63%) had their lesions excised, and 77 (86%) had pathologic diagnoses of benign tumors and 13 (14%) of malignant tumors. The following characteristics were statistically significant in the diagnosis of the breast cancer (c²): masses with retrotumoral shadowing (p=0.0001), irregular shape (p=0.0007), heterogeneous internal echoes (p=0.0015) and vertically oriented - taller than wide (p<0.0001). The presence of halo of bright echoes anterior to the lump and the presence of wider Cooper ligaments were not related to the correct diagnosis of malignancy in this trial. Conclusion: ultrasound is a diagnostic method that can help physicians between the differentiation of benign and malignant breast lumps. The presence of retrotumoral shadowing, irregular shape, heterogeneous internal echoes and vertical orientation - lesions taller than wide - were related to the pathologic diagnosis of breast malignancies.
