Bilateral Phyllodes in a 12-Year-Old Adolescent: Report of a Rare Case

Phyllodes tumors, previously known as cystosarcoma phyllodes, are fibroepithelial tumors that consist of epithelial and cellular stromal components. These tumors have a predilection to recur after wide local excision and to attain massive sizes. They account for less than 0.5% of cases of all breast neoplasms and are primarily found in the third to fourth decade of life, and rarely in adolescence. However, less than 25 cases are reported to date wherein this tumor is found in adolescent females, with this case being one of those. This is a report of a rare case of a 12-year- old premenarchal female with bilateral phyllodes tumor, highlighting its peculiarities, diagnostic features, and surgical management in view of the patient's age and quality of life.
