Background:
Annular erythema is a rare manifestation of leukocytoclastic vasculitis. It may be associated with various drugs, infections, malignancies, or systemic diseases.
Case Description:
A 36-year-old woman with no personal medical history presented with annular erythema with target lesions and petechial purpura. The patient had fever and joint arthralgia. A skin biopsy showed leukocytoclastic vasculitis with IgA deposits on direct immunofluorescence. The diagnosis of immunoglobulin A vasculitis with annular leukocytoclastic vasculitis was made. The patient showed global improvement with topical steroids without relapse.
Conclusion:
An annular variant of leukocytoclastic vasculitis is a rare manifestation of immunoglobulin A vasculitis.
Learning Points:
Annular erythema may reveal an IgA vasculitis.Annular leukocytoclastic vasculitis is a rare manifestation of IgA vasculitis.This presentation is treated with topical steroids.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
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...
