A Case of Early Gastric Cancer with Sarcoid Reaction

Abstract

A 36-year-old woman with continuous fever and abdominal pain visited our hospital for further examination. Endoscopy revealed a 0-IIb lesion in the greater curvature of the lower body of the stomach, and biopsy revealed signet-ring cell carcinoma. Abdominal CT showed swelling of multiple lymph nodes around the abdominal aorta. Pylorus-preserving gastrectomy was performed based on the results of intraoperative pathological examinations that showed no regional lymph node metastases. Pathological findings were sig, pT1a(m), ly0, v0, pN0, pPM0, pDM0, cM0, Stage IA and epithelioid cell granulomas were observed in the dissected lymph nodes and mucosal layer of the stomach. Sarcoid reaction of early gastric cancer was diagnosed because this case failed to fulfill the diagnostic criteria for sarcoidosis (bilateral hilar lymphadenopathy, high serum angiotensin converting enzyme level, skin or ocular involvement).
