Transverse ulcers are seen in
**Core Concept**
Transverse ulcers are a type of mucosal injury that occurs in the stomach or duodenum, characterized by linear or longitudinal lesions that traverse the gastric or duodenal mucosa. This phenomenon is associated with specific pathophysiological mechanisms and clinical conditions.
**Why the Correct Answer is Right**
Transverse ulcers are typically seen in patients with **Zollinger-Ellison syndrome**, a rare disorder caused by a gastrin-producing tumor. Elevated gastrin levels lead to excessive acid production, resulting in **mucosal injury** that manifests as transverse ulcers. The pathophysiology involves the activation of gastric parietal cells, leading to increased acid secretion and subsequent mucosal damage.
**Why Each Wrong Option is Incorrect**
**Option A:** **Erosive gastritis** typically presents with superficial mucosal damage and does not typically exhibit transverse ulcers.
**Option B:** **Duodenal ulcers** are typically circular or oval in shape, not transverse.
**Option C:** **Cushing's ulcer** is an acute gastric ulcer associated with severe head trauma or intracranial disease, not typically transverse.
**Clinical Pearl / High-Yield Fact**
In patients with Zollinger-Ellison syndrome, the presence of multiple, transverse ulcers in the stomach or duodenum should raise suspicion for this rare disorder.
**Correct Answer:** D. Zollinger-Ellison syndrome.
