Summary
A rare case of hepatoid adenocarcinoma (HAC) was found in the gastric submucosa. Submucosal tunneling endoscopic resection successfully removed the gastric tumor, marking a first for this origin.
Area of Science:
- Gastroenterology
- Oncology
- Surgical Pathology
Background:
- Submucosal lesions in the gastric cardia can present diagnostic challenges.
- Accurate pre-operative characterization is crucial for appropriate management of gastric tumors.
Observation:
- Esophagogastroduodenoscopy identified a submucosal lesion in the gastric cardia.
- Endoscopic ultrasonography indicated a hypoechoic lesion originating from the muscularis propria, suggestive of leiomyoma or stromal tumor.
Findings:
- Submucosal tunneling endoscopic resection was successfully performed.
- Histopathological diagnosis confirmed hepatoid adenocarcinoma (HAC) of the stomach.
- This represents the first reported case of gastric HAC originating from the submucous layer.
Implications:
- Highlights the importance of considering rare diagnoses like hepatoid adenocarcinoma in submucosal gastric lesions.
- Demonstrates the efficacy of submucosal tunneling endoscopic resection for specific gastric tumors.
- Contributes to the understanding of gastric cancer origins and management strategies.

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

743
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

The stomach comprises several layers that work together to facilitate digestion and protect the organ. The outermost layer is called the serosa, which provides support and protection to the stomach. The muscularis externa layer is responsible for the mechanical breakdown of food by contracting and moving the stomach. The submucosa layer, located beneath the muscularis externa, contains connective tissue, blood vessels, nerves, and glands that secrete mucus and other substances essential for...

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
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...
