title: A case of genitourinary Crohn's disease.
abstract: Scrotal swelling in young boys is a common problem. The differential diagnosis includes testicular torsion, epididymoorchitis, and idiopathic scrotal edema. We report the unusual case of a 17-year-old boy who presented with recurrent episodes of penile and scrotal edema as extraintestinal manifestations of Crohn's disease. Genitourinary complications of Crohn's disease are not uncommon; however, they more typically present in the form of nephrolithiasis, obstructive uropathy, and enterovesical fistulization. Few reports have described Crohn's disease presenting with isolated genital edema in the absence of associated intestinal or systemic symptoms.
