Cutaneous polyarteritis nodosa associated with Crohn's disease
Diseases of the Colon and Rectum
|May 1, 1980
Summary
Crohn's disease can manifest with skin issues like tender nodules. Histology confirmed granulomatous panarteritis in nodules, distinct from the colitis, highlighting the need for accurate diagnosis.
Area of Science:
- Dermatology
- Gastroenterology
- Pathology
Background:
- Crohn's disease is a chronic inflammatory bowel disease.
- Cutaneous manifestations of Crohn's disease are diverse.
- Polyarteritis nodosa is a rare systemic vasculitis.
Observation:
- A 13-year-old girl with Crohn's colitis presented with painful skin nodules and cords.
- Histology of nodules revealed granulomatous panarteritis in subcutaneous arteries.
- The colon showed granulomatous transmural colitis without vasculitis.
Findings:
- The case highlights a rare association between Crohn's disease and cutaneous polyarteritis nodosa.
- Granulomatous inflammation was present in both the skin and the colon, but vasculitis was limited to the skin.
- Accurate histologic evaluation is essential for diagnosis.
Implications:
- This case underscores the importance of considering vasculitis in Crohn's disease patients with skin lesions.
- Early and accurate diagnosis through histology can guide appropriate management.
- Further research into the pathogenesis of cutaneous manifestations in Crohn's disease is warranted.
