Abstract:
In male-to-female gender transition, individuals request a number of interventions, including hormonal therapy, to promote feminizing characteristics. Estrogen-based medication is prescribed to increase breast development, decrease facial hair, promote feminine adipose tissue deposition, and soften skin. Surgical breast augmentation to supplement unsatisfying breast growth after hormonal therapy is a common and well-studied course of management for such transgender patients. In a departure from convention, the authors present a case of symptomatic macromastia requiring surgical breast reduction in a transgender woman following 24 years of hormonal therapy and illicit silicone injections in multiple areas of her body, including the breasts.
