Abstract:
Pseudohyperaldosteronism, or Liddle syndrome, is a rare, autosomal dominant condition characterized by early-onset hypertension, often associated with hypokalemia and metabolic alkalosis. Martorell hypertensive ischemic leg ulcer is a rare, underdiagnosed ulcer characterized by subcutaneous arteriolosclerosis, classically appearing over the dorsolateral lower extremity or Achilles tendon in patients with hypertension and diabetes. It presents an important diagnostic challenge because it can appear grossly similar to other entities such as pyoderma gangrenosum or venous stasis ulcers, but requires surgical intervention. This article presents a case study of surgical management of a Martorell ulcer in a 69-year-old woman with Liddle syndrome. To the authors' knowledge, this is the first case reported in the literature of this rare ulcer occurring secondary to this rare cause of hypertension.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
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.
Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
Pathophysiology of Peptic Ulcer Disease: Injurious Factors
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...
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...
