Introduction: Small intestinal metastasis from oesophageal carcinoma is rare. We report a case of small intestinal metastases from oesophageal carcinoma presenting as a perforation and discuss the aetiology with other cases of small intestinal metastasis from oesophageal carcinoma reported in previous literature.
Presentation: An 86-year-old man presented with fever and coughing. He had choked while eating and had history of weight loss. He was diagnosed with aspiration pneumonia. Two days after the admission, he complained of abdominal pain. Physical examination revealed guarding and rebound tenderness in the upper abdomen. A contrast computed tomography of the abdomen showed ascites, free air, and irregular thickness of the small intestinal walls. Small intestinal perforation was noted, and surgical resection of the small intestine was performed. The pathological findings of the resected small intestine revealed ulcers with squamous cell carcinoma, and upper gastrointestinal endoscopy demonstrated oesophageal tumour, whose biopsy revealed squamous cell carcinoma. A diagnosis of small intestinal metastases from oesophageal carcinoma was made, but the patient died one month after the diagnosis.
Discussion: Most cases found in the literature of oesophageal tumour involve squamous cell carcinoma with male patients, and specific symptoms are divided into obstruction and perforation. All patients with small intestinal metastasis from oesophageal carcinoma who survived were treated by a combination of resection and radiation and/or chemotherapy; thus, immediate treatments seem essential to improve the prognosis.
Conclusion: Physicians should keep in mind the possibility of small intestinal metastasis when patients with a history of oesophageal cancer have abdominal symptoms.
