Benign duodenal tumours have very rarely been reported in captive non‐human primates and are also rare in human beings. Brunner's gland hyperplasia has not been fully described in a non‐human primate. Here, we report Brunner's gland hyperplasia in a geriatric chimpanzee, which was an incidental finding during post‐mortem examination.
