Benign breast cyst is common in females in the reproductive age group. However, it is rare in males. Males without gynecomastia are not considered candidates for development of benign breast cyst. Here, we report a case of a large benign apocrine cyst in a young adult male breast. A 16-year-old adolescent male presented with complaints of swelling on the right breast of 2-month duration. He noticed gradual increase in the size of the swelling. No history of nipple retraction, nipple discharge, similar swellings in the opposite breast or axilla, pain, or fever. Examination of the right breast showed a soft cystic swelling under right nipple areolar complex of size 4 × 4 cm size. Ultrasound evaluation of right breast showed oval anechoic cystic lesion measuring 4.4 × 4 × 1 cm in retroareolar location with fine internal contents and axilla showed a small lymph node with preserved hilum (maximum size 6 mm) in right axilla. FNA from the breast cyst yielded turbid fluid and cytology was inconclusive. He underwent excision biopsy under GA. Histopathology showed benign apocrine cyst with papillary hyperplasia and prominent apocrine metaplasia. His postoperative period and outpatient follow-up were uneventful. Apocrine cyst in male breast is a rare clinical entity. Triple assessment and excision helps in complete recovery.
