Male Tuberous Breast: A Rare Variant of Gynecomastia.

Tuberous breast deformity is well described in females but remains rare in males, where it represents an uncommon morphological variant of gynecomastia. It is characterized by a constricted breast base, enlarged nipple-areolar complex (NAC), inframammary fold indentation, and apparent parenchymal herniation into the areola. We report the case of a 17-year-old male presenting with progressive bilateral breast enlargement since the age of 11, with marked worsening at 16 years and significant psychosocial distress. Clinical examination revealed bilateral glandular gynecomastia with enlarged NACs, mild asymmetry, and global base constriction consistent with a severe tuberous deformity. Ultrasonography showed homogeneous glandular hypertrophy, and endocrine evaluation was normal. Surgical correction using glandular transection and release of constricting elements resulted in satisfactory aesthetic outcomes without complications. Male tuberous breast deformity is an underrecognized entity requiring tailored surgical management addressing both glandular excess and base constriction.
