Tumor necrosis factor-α inhibitor-induced morphea and psoriasiform dermatitis in a pediatric patient with Crohn's disease.

Tumor necrosis factor-alpha inhibitor therapy for inflammatory bowel disease may be associated with paradoxical cutaneous adverse events, most commonly psoriasiform eruptions. We present the case of a pediatric female patient with Crohn's disease who developed multiple concurrent cutaneous eruptions while on infliximab treatment, including morphea, psoriasiform dermatitis, and genital lichen sclerosus. Although refractory to skin-directed treatments, all three conditions resolved upon discontinuation of infliximab, supporting their development as a paradoxical reaction to infliximab therapy.
