A CASE OF MINUTE SIGNET-RING CELL CARCINOMA OF THE STOMACH

Abstract

We reported an extremely rare case of minute signet ring cell carcinoma of the stomach and described the clinicopathological findings of this lesion. A 59-year-old woman was referred to our hospital with minute gastric signet ring cell carcinoma. It was revealed to be a round discolored lesion 4 mm in diameter and type 0-IIb according to the Japanese classification of gastric carcinoma (superficial flat type) by routine gastroduodenoscopy for health screening. The gastroduodenoscopy examination showed that the color change of this lesion was pathognomonic. This lesion was unclear upon examination of the gastric biopsy specimen, but it was again identified by magnifying endoscopic diagnosis using NBI. Subsequently this minute lesion was treated with endoscopic submucosal dissection. The patient has been free of recurrence for 30 months.
