Pancreatic Metastasis from Malignant Phyllodes Tumor of the Breast: A Rare Case Report and Literature Review

Abstract

Phyllodes tumors (PTs) are defined as a fibroepithelial neoplasm of the breast. Although most of the Phyllodes tumors are benign, malignant cases do uncommonly occur. Pancreatic metastasis from malignant Phyllodes tumor is extremely rare, and only 5 cases have been reported in the literature. We presented a case of a pancreatic metastasis in a patient diagnosed with a malignant phyllodes tumor who had completed her treatment two years ago. Our objective is to draw the readers’ attention to the possibility of pancreatic metastases from malignant phyllodes tumor in patients who had remission of malignant phyllodes and presented with signs and symptoms of primary pancreatic carcinoma.
