Brunner’s gland hyperplasia associated with lipomatous pseudohypertrophy of the pancreas presenting with gastrointestinal bleeding: A case report

Figure 4 Histological findings of duodenal and pancreatic biopsy specimens. A and B: The duodenal biopsy showed lobulated proliferation of submucosal Brunner’ glands comprising benign-looking acini lined by mucous cells with basal nuclei without atypia, which was consistent with Brunner’s gland hyperplasia. C and D: Percutaneous pancreatic biopsies revealed adipose tissue replacing the pancreatic parenchyma. Some pancreatic acini were identified with a scattered distribution. Hematoxylin and eosin stain (A–D). Original magnification: (A, C, D) × 40, (B) × 100.
