Phyllodes tumor in adolescent

a case report of a 13-year-old girl

Abstract

Phyllodes tumors are rare fibroepithelial breast neoplasms. In a less aggressive form, they behave in a similar fashion to the fibroadenoma, and the only differences can be seen in the tumor size and/or speed of growth. We reported the case of an underage girl, with bilateral gynecomastia, who underwent left mastectomy and right breast quadrantectomy. The histopathological diagnosis showed stromal proliferation, consistent with phyllodes tumor that compromised the entire length of the surgical specimens, including the skin areolar region. Diagnosis of phyllodes tumor is rare in breasts of adolescents. The reported case is of great importance due to the patient’s age, and location and extent of the injury.
