It has been reported that majority of cases of gigantomastia, also known as breast hypertrophy and macromastia, occur during either pregnancy or puberty. Gigantomastia is a rare disorder that does not have a clear etiology or well-established risk factors. We present a 26-year-old female patient who appeared to have pregnancy-associated gigantomastia recurrence, large accessory breast and, ectopic breast tissue at external genital three years after bilateral breast reduction surgery. The patient successively underwent bilateral mastectomy and vulvar tumor resection. Breast hypertrophy and progenital ectopic breast were pathologically confirmed. This the first case of gigantomastia reported worldwide.
