Context Is Everything: An Unusual Breast Core Biopsy Case

Changes in breast tissue in female-to-male transsexuals following gender reassignment and androgen therapy can cause difficulties in interpreting breast core biopsies. Clinical history and awareness of histological changes in breast tissue associated with androgen treatment are important in such cases. Specimen mislabeling is a potential pitfall to be borne in mind while evaluating unusual presentations in breast core biopsies. We report a case of a 58-year-old male with a well-defined supra areolar lesion clinically thought to be a fibroadenoma.
