[A Case of Small Intestinal Metastasis from Small Cell Lung Carcinoma Presenting with Gastrointestinal Bleeding]

An 80-year-old woman with a history of lobectomy for small cell lung carcinoma(SCLC)presented with melena 2 years after surgery. Contrast-enhanced abdominal CT and enteroscopy revealed a bleeding tumor at the proximal jejunum. Partial small bowel resection was performed for hemostasis and diagnosis. Histopathology confirmed jejunal metastasis from SCLC. Due to advanced age and ongoing hemodialysis, no adjuvant therapy was administered. She remains recurrence-free 7 months postoperatively. Small intestinal metastasis from SCLC is rare, but long-term survival after resection has been reported. We report this rare surgical case of jejunal metastasis from SCLC with gastrointestinal bleeding.
