a Gross examination of the specimen (185 mm × 150 mm). Gastric kyphosis measures 110 mm in length; duodenum measures 20 mm × 70 mm. A 15 mm × 10 mm ulcerative lesion (circle) is observed 64 mm from the proximal gastric pylorus and 44 mm from the distal gastric pylorus. b Histopathological examination of the gastric ulcerative lesion. An active ulcer extending into the submucosa is observed (UI–II). Inflammatory exudates are observed at the base of the ulcer, and hyperplasia of the glandular and juvenile regenerating epithelia are observed. A basophilic crystalline substance (yellow arrow), possibly a cation-exchange resin, is observed at or near the base of the ulcer
