A Case of Primary Esophageal Small Cell Carcinoma with Gastric Metastasis / 대한소화기내시경학회지

ABSTRACT

Gastric metastasis of malignant tumors is relatively rare but has been reported in cases of malignant melanoma, lung cancer, breast cancer and squamous cell carcinoma of the esophagus. Primary small cell carcinoma of the esophagus is very rare and is an extremely aggressive tumor. Regional lymph node involvement, and distant metastasis to other organs including liver, bone, skin, lung, bone marrow, and brain are common at the time of initial diagnosis. To date, there has been no case reported of gastric metastasis from primary esophageal small cell carcinoma. A 72-year-old man presented with dysphagia for 2 months. An esophagogastroduodenoscopy revealed esophageal carcinoma with a submucosal tumor in the upper body of the stomach. Pathologic examination revealed an esophageal small cell carcinoma, and gastric submucosal infiltration of the small cell carcinoma was noted. We report a case of primary esophageal small cell carcinoma with submucosal tumor like gastric metastasis.
