A CASE OF LACTATING ADENOMA WITH RAPID ENLARGEMENT

We experienced a case of lactating adenoma with a rapid enlargement. A 28-year-old woman at 12 weeks' pregnancy was seen at the hospital because of a rapidly growing mass in the right breast with skin pigmentation. Physical examinations, mammography, ultrasonography, thermography, and aspiration biopsy cytology could not rule out malignancy. The patient herself requested a resection of the tumor and was operated on. The specimen showed a 14×9cm capsulated tumor. Pathologically it was lactating adenoma.
