Dermatological signs during inflammatory bowel diseases

Area of Science:

• Gastroenterology and Dermatology
• Internal Medicine

Background:

• Crohn disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBD) characterized by bowel ulcerations.
• Skin, oral, or perianal lesions can manifest in IBD patients, sometimes preceding bowel symptoms.
• Dermatologists may encounter skin conditions that indicate underlying IBD.

Purpose of the Study:

• To highlight the association between specific dermatological conditions and inflammatory bowel disease.
• To emphasize the role of dermatologists in suspecting and diagnosing IBD based on skin manifestations.

Main Methods:

• Review of clinical presentations linking dermatological findings to IBD.
• Analysis of common skin lesions associated with IBD, including pyoderma gangrenosum (PG) and erythema nodosum (EN).

Main Results:

• Pyoderma gangrenosum and erythema nodosum are well-recognized dermatological signs associated with IBD.
• Skin lesions can be the initial presentation of IBD, prompting further investigation.
• The presence of these skin conditions necessitates consideration of underlying bowel pathology.

Conclusions:

• Dermatological manifestations like PG and EN can serve as crucial early indicators of IBD.
• Collaboration between dermatology and gastroenterology is vital for comprehensive patient care.
• Treatment for IBD, when indicated by skin lesions, may range from corticosteroids to anti-TNF biologics.
