Fungating malignant phyllodes tumor

Phyllodes tumors are extremely uncommon neoplasms that are usually benign. Patients with phyllodes tumors typically present with a well-circumscribed, painless, firm, and mobile mass or nodule characterized by rapid growth in a short period of time. It is recommended that these tumors be excised even though it may look as a fibroademoma. Our patient presented with a left nipple mass with rapid growth. The patient had been previously diagnosed with malignant phyllodes tumor, which was excised with adequate margins, later presenting with an exophytic mass extending from the nipple along with bloody discharge. The patient underwent a complete mastectomy of the left breast without a lymph node dissection, and pathology revealed an additional focus of intramammary myoepithelioma. The aim of this case report is increase awareness of these tumors and their potentially unusual presentations to allow clinicians the ability to recognize these neoplasms earlier as well as recognizing the need for better adjuvant therapy.
