Concurrent gastric sarcoidosis and early gastric cancer distinguished by magnifying narrow band imaging

: A 46-year-old woman with a history of pulmonary sarcoidosis and Helicobacter pylori (HP)-associated chronic gastritis underwent a screening esophagogastroduodenoscopy. About 10 flat-yellowish lesions 5-20 mm in size were found in the gastric body. Adjacent to one of those flat-yellowish lesions (Fig. 1a, white arrow), a 5-mm slightly depressed lesion was detected (Fig. 1a, black arrow). Borderline of those lesions was unclear in white-light imaging. In magnifying narrow-band imaging (M-NBI), although the yellowish lesion did not have a clear demarcation line, boundary of the lesion became recognizable.
