Summary

Gastric perforation secondary to metastasis from breast cancer occurs infrequently. We present the case of a 72-year-old postmenopausal female patient with a known history of lobular carcinoma of the breast who presented to a district general hospital with a clinical diagnosis of an acute abdomen. Further contrast-enhanced CT scan demonstrated free gas and fluid in the abdomen. She underwent emergency exploratory laparotomy and onlay Graham's omentopexy patch due to 1×1 cm prepyloric gastric perforation. Final histopathology proved the presence of metastatic malignant cells in the breast origin. We discuss the issues involved in postoperative investigation and management.
