Abstract:
Cutaneous intestinal either metaplasia or ectopia has mostly been described around intestinal stomas or in patients with Crohn disease. In this study, we described a unique case of cutaneous metaplasia on the elbow of a 25-year-old man who had a clinical history of epidermolysis bullosa simplex, but had no history of any gastrointestinal disease. The lesion had been clinically stable for 5 years. Histopathologically, the epithelium showed many columnar cells with mucinous cytoplasm, with no atypia or mitoses. The proliferation rate was low (7% by Ki67). The metaplastic areas expressed epithelial membrane antigen, carcinoembryonic antigen, cytokeratin 7, MUC5AC, MUC2, and Cyclin-D1.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory 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...
