Abstract:
The patient, a 43-year-old Japanese man suffering from duodenal ulcer and reflux esophagitis, was admitted to our hospital because of submucosal tumor in the antrum and obstructive stenosis of duodenum. Several imaging tests could not rule out the possibility of malignant disease. Therefore, the patient was surgically treated. Pathohistological examination of resected tissue demonstrated Heinrich type I heterotopic pancreas in the gastric lesion and submucosal abscess in the duodenal lesion with stenosis. In this case, it was considered that the heterotopic pancreas caused chronic inflammation to form the gastric tumor, and submucosal abscess leading to the severe duodenal stenosis.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Pancreas
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short and...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
