Jejunal obstruction caused by metastasis from an undiagnosed breast cancer: a case report.

Solitary metastasis from breast carcinoma to the gastrointestinal tract is an uncommon finding. We describe a female patient with a solitary jejunal metastasis from an undiagnosed breast cancer who presented to the emergency department with a bowel obstruction. Abdominal surgery was performed, revealing a jejunal stenosis from a metastatic lobular carcinoma. The primary tumor in the left breast was subsequently diagnosed and surgically removed.
