Abstract:
A 16-year-old female patient with previously diagnosed acne vulgaris was transferred to our clinic in reduced general condition with rapidly progressive and extremely painful ulcerations. In the laboratory exam, inflammatory parameters were highly elevated, but she was normothermic. Based on the findings, we diagnosed multilocular pyoderma gangrenosum. Further investigations established the diagnosis of primary biliary cholangitis as the underlying condition. Treatment with systemic corticosteroids was initiated and we started therapy with ursodeoxycholic acid. This led to improvement within a few days. PAPA-syndrome (pyogenic arthritis, pyoderma gangrenosum and acne vulgaris) could be ruled out by genetic analysis.

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.

01:17Gastritis-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...
