[Skin manifestations of pediatric inflammatory bowel disease]. / Manifestaciones cutáneas de la enfermedad inflamatoria intestinal.

ABSTRACT

Skin manifestations have been described in 10-15% of patients with inflammatory bowel disease (Crohn's disease, ulcerative colitis, indeterminate colitis/inflammatory bowel disease type unclassified). There are limited data on the prevalence of these manifestations in paediatric patients, but recent studies have reported its presence in 8% of them at diagnosis. Our aim is to report the different skin manifestations observed in our paediatric patients with inflammatory bowel disease. Case 1 Erythema nodosum at Crohn's disease diagnosis. Typical presentation with painful erythematous nodules in the pretibial region and with good response to infliximab. Case 2 Coexistence of pyoderma gangrenosum and mucocutaneous Sweet's syndrome in a Crohn's disease patient. A rapidly progressive disease that was controlled with systemic steroids but with significant residual lesions. Case 3 and 4 Metastatic Crohn's disease with good response to infliximab.
