Background:
Cutaneous manifestations are the most common extra intestinal manifestations associated with inflammatory bowel disease (IBD).
Aim:
To assess the epidemio-clinical profile of skin manifestations in IBD.
Methods:
A prospective and descriptive study was conducted. We have examined skin, mucosa, hair and nails, of all patients with an IBD during one year.
Results:
One hundred-ninety-five patients were included. Crohn's disease (CD) was noted in 154 cases (79.8%), ulcerous rectocolitis (UC) in 39 cases (21.2%) and inclassable IBD in 2 cases. Cutaneous manifestations were found in 91% of Crohn's patients and in 92% of UC patients. Granulomatous perianal skin lesions were the main cutaneous manifestations of CD (53%). The most common affected sites were ano-perineal fistulae, perianal and perineal fissures and oedematous and infiltrated perianal and genital plaques. Reactive lesions (Erythema nodosum, Pyoderma gangrenosum, Aphthous stomatitis) were noted in 14 cases. Skin manifestations due to malabsorption were also frequently observed (101 cases: 51.7%).Other dermatoses implicating various mechanisms such as psoriasis, alopecia areata, vitiligo, rosacea, lichen planus, were also noted. Adverse skin manifestations due to treatment (folliculitis, acne, macula-papular rash and DRESS syndrome) were present in 16 cases.
Conclusion:
Our series is characterized by a high frequency of cutaneous manifestations associated to IBD. A better recognition of these skin manifestations by the physician may improve their management.

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 transmural...

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...
