Ectopic gastric mucosa (EGM) of the jejunum is rare. We report an 81-year-old man with perforated peptic ulcer of the jejunum originating from EGM. Emergency segmental resection of the jejunum was performed with satisfactory immediate results. Diagnosis after surgery was established by histopathology. In addition, sections were examined immunohistochemically using antibodies against MUC5AC, MUC6 and MUC2. Hematoxylin-eosin-stained sections showed glandular differentiated tissue interposed between normal small bowel epithelium. EGM was positive for MUC5AC and MUC6, and negative for MUC2. Histological examination of the resected specimen confirmed that the perforation was caused by a peptic jejunal ulcer associated with EGM. To our knowledge, this is the first reported case of perforated peptic ulcer of the jejunum with EGM in an elderly patient.
