Abstract

Crohn's disease is a systemic inflammatory and granulomatous disease, mainly involving the gastrointestinal tract with extraintestinal manifestations such as the skin, liver and bone. Cutaneous manifestations of Crohn's disease are relatively common; however, the groin is an unusual site for cutaneous Crohn's disease. A 36-year-old male presented with mild pruritic nodules on the left groin for 2 months. Nine years ago, he was diagnosed with intestinal Crohn's disease by endoscopic biopsy. Histopathologic examination of the cutaneous lesion showed non-caseating granulomatous reactions composed of multinucleated giant cells with lymphohistiocytic infiltration in the dermis. Staining for periodic acid-Schiff and acid-fast bacilli was negative. From these findings, we diagnosed these lesions as cutaneous Crohn's disease. The lesions were markedly improved with three rounds of intralesional steroid injection.
