Disseminated malignant phyllodes: Presentation after a decade.

ABSTRACT

Phyllodes tumors are rare biphasic fibroepithelial lesions of the breast and account for 0.3%-0.5% of primary breast tumors. Malignant phyllodes tumor has a 10%-26% risk of distant metastasis. The most common site of metastasis is lungs followed by bone and soft tissue. This is a rare case of a 42-year-old female with a previous history of malignant phyllodes tumor breast. She presented after 10 years with metastases to multiple sites including lung, abdominal wall, retroperitoneum, bone, and brain. These tumors have a poor overall survival. Accurate diagnosis and aggressive management of malignant phyllodes tumors can help in effective treatment at diagnosis and for close follow-up of the patients.
