title: Penoscrotal edema and purpura in a 12-year-old boy: a case report and review of causes.
abstract: We report the case of a 12-year-old patient with previously diagnosed Crohn disease who presented with penile edema and purpura, with extension into the scrotum. Subsequent work-up including biopsy led to the diagnosis of extraintestinal Crohn disease, a rare manifestation in the genital region. Prompt treatment with steroids led to complete resolution of both penoscrotal edema and purpura. We describe our case, followed by a discussion of etiologies of penoscrotal edema and purpura as a review for the practicing pediatric urologist.
