Sarcomatoid carcinoma of the jejunum presenting as obscure gastrointestinal bleeding in a patient with a history of gliosarcoma.
Small bowel malignant tumors are rare and sarcomatoid carcinomas have rarely been reported at this site. We report a 56-year-old woman, with history of an excised gliosarcoma, who presented with recurrent obscure gastrointestinal bleeding. She underwent endoscopy and colonoscopy, which failed to identify the cause of the bleeding. The abdominal computed tomography scan located a tumor in the small bowel. Pathology revealed a jejunal sarcomatoid carcinoma. She developed tumor recurrence and multiple liver metastases shortly after surgery. Immunohistochemistry is required for accurate diagnosis. Sarcomatoid carcinoma is a rare cause of obscure gastrointestinal bleeding, which is associated with a poor prognosis.
