Male Breast Abscess Mimicking Malignancy: Clinical, Mammographic, Ultrasound, and Shear-Wave Elastography Findings

A variety of same pathologic conditions in the female breast, from benign to malignancy, have been reported for the male breast. In a symptomatic male patient with a palpable abnormality, gynecomastia and skin lesions account for the majority of pathologic conditions [1-3]. Breast abscess is also possible benign condition in men, but it is extremely rare [1-3]. Male breast abscess may have unfavorable imaging features which had to be differentiated from malignancy as like in women, requiring tissue sampling [4]. However, to date, there have been few literatures and case reports about male breast abscess [5-9]. Only limited information about their clinical or imaging features is available [1-3]. In this report, we describe a rare case of male breast abscess mimicking malignancy in clinical, mammographic, Ultrasound (US), and shear-wave elastographic findings. To the best of the author’s knowledge, this is the first case report of male breast abscess focusing on imaging features including US elastography.
