A case of subareolar abscess in the male breast: Usefulness of magnetic resonance imaging scan for diagnosis

Introduction: Subareolar abscess in the male breast is extremely rare. The main concern with this condition is performing the differential diagnosis, since clinically it often resembles breast cancer. Case Report: A 30-year-old Japanese male presented with pain and swelling of the left breast. Physical examination revealed a 3.0x3.0 cm palpable lump with redness of the skin in the left subareolar region. Magnetic resonance imaging (MRI) scan showed a ring-enhancing mass without wash out with central necrosis below the left nipple, suggesting subareolar abscess. A core needle biopsy was performed, and histological findings revealed granulation tissue with the infiltration of numerous neutrophils, a finding that was compatible with subareolar abscess. Conclusion: Male subareolar abscess is quite a rare disease, however, awareness of how to perform differential diagnosis of subareolar abscess and the use of MRI scan may help in making a definitive diagnosis of subareolar abscess in the male breast and might aid in the proper management of the condition.
