Metastatic Crohn's disease involving the penis

Metastatic Crohn's disease is a rare complication in Crohn's disease and there have been only several cases of metastatic Crohn's disease involving the penis. We report one such case. A 22-year-old male student developed anal pain and alternative constipation and diarrhea in December, 1985, followed by diarrhea and lower abdominal pain in January, 1986. He was diagnosed as having Crohn's disease of ileocolitis type. He was admitted to our hospital in July, 1987 because of exacerbation of Crohn's disease. He had anal tags. Soon after admission, two red swollen lesions with central ulcer and erosions were demonstrated at the eversion of the foreskin adjacent to coronal sulcus. Histology of the lesions revealed granulomas with epithelioid cells and giant cells. The lesion responded to a topical steroid. Eight cases of metastatic Crohn's disease involving the penis are briefly reviewed.
