Metastatic Crohn's Disease

Area of Science:

• Gastroenterology
• Dermatology
• Pathology

Background:

• Crohn's disease (CD) is a chronic inflammatory bowel disease.
• Extraintestinal manifestations (EIMs) of CD can affect various organs.
• Cutaneous involvement is a rare but recognized EIM of CD.

Observation:

• A patient initially diagnosed with ulcerative colitis presented with intra-abdominal abscesses.
• The patient developed ulcerated cutaneous lesions.
• Skin biopsy revealed noncaseating granulomas, characteristic of metastatic Crohn's disease.

Findings:

• Metastatic cutaneous Crohn's disease can mimic other conditions, including ulcerative colitis.
• The diagnostic hallmark is the presence of noncaseating granulomas in the skin, anatomically separate from the gastrointestinal tract or fistulas.
• This case underscores the importance of thorough histopathological examination for accurate diagnosis.

Implications:

• Accurate diagnosis of metastatic Crohn's disease is crucial for appropriate management.
• Early recognition and treatment can lead to favorable patient outcomes.
• This case contributes to understanding the diverse clinical presentations of Crohn's disease.
