Gender dysphoria is a diagnosis whereby an individual identifies as the opposite gender. The management of patients seeking female-to-male (FTM) transition includes hormonal therapy and surgical intervention, including mastectomy. The aim of this study was to characterize the immunohistological findings in resection specimens from FTM patients. ⋯ We identified gynaecomastoid change at a significantly higher rate than previously reported in female patients. We support the continued gross and histological evaluation of FTM specimens in light of the identification of atypia in one case.
