Introduction: The tumor Phyllodes is a rare tumor in the breast with an incidence of 1: 100,000 inhabitants and it presents from 0.3% to 0.9% of breast tumors, mostly at the age of 35 to 55 years, being uncommon at the extremes of life.
Clinical case: The first case report is presented at the ISSEMYM maternity hospital in Toluca of an 11 year old girl who was admitted to the emergency department for having a tumor in the right breast that has been growing rapidly for a week (10 × 9 × 5 cm) causing itching, hyperemia, painful palpation, which did not remit with medical management, is valued by the pediatric oncological surgery service, which proposed emergency surgical treatment (tumorectomy) since it did not involve the mammary gland and was not observed by malignancy data (by Ultrasound and Tomography); the histopathological result was Phyllodes tumor. Follow-up was given in the outpatient clinic at a month and the sixth month with imaging control without evidence of tumor activity.
Conclusion: The majority of lesions in children and adolescents are benign and the surgery that deforms the normal anatomy of the breast should be avoided.
