Phyllodes Tumor Presenting with a Rare Widespread Abdominal Metastases: A Case Report and Review of the Literature

Abstract

Phyllodes tumour is a rare breast neoplasia. The malignant variant is even rarer and it is unusual for abdominal metastases to occur sparing the more contiguous chest cavity and lungs. The patient presented with abdominal pain and distension, protracted vomiting and rapid weight loss five weeks after simple mastectomy for a bosselated, fungating right breast lesion. Exploratory laparotomy was carried out for the unexplained acute abdomen and it revealed an inoperable, generalized abdominal seedlings. This report illustrates a rare case of metastases at an unusual site from malignant phyllodes tumor occurring shortly after simple mastectomy.
