Inflammatory bowel disease presenting with pyodermatitis-pyostomatitis vegetans in a pediatric patient: A case report and review of the literature.

Pyodermatitis-pyostomatitis vegetans (PD-PSV) is rarely reported in the pediatric population. Here, we provide a review of pediatric PD-PSV in the literature and report a case of widespread PD-PSV in a 15-year-old male without a previous history of inflammatory bowel disease or gastrointestinal symptoms. Clinical, histological, and immunopathological workup established PD-PSV and revealed subclinical Crohn's disease. Treatment with infliximab was effective in inducing rapid resolution of the lesions.
