title: A Case of Phyllodes Tumor with Bloody Nipple Discharge in Juvenile Patient.
abstract: We report a rare case of phyllodes tumor of the breast in a juvenile patient with bloody nipple discharge. An 11-year-old girl had a chief complaint of a palpable 5 cm well-circumscribed tumor with nipple discharge in the left breast. The histopathological diagnosis of the resected specimen was benign phyllodes tumor showing extensive areas of hemorrhagic necrosis. The bloody nipple discharge was caused by spontaneous infarction of the tumor. Preoperative ultrasonography and galactography were helpful in evaluating the mechanism of nipple dicharge from the tumor. Although phyllodes tumor must be differentiated from fibroadenoma, the present case was histopathologically identical to phyllodes tumor.
