[Ischemic colitis in Reiter syndrome].

Involvement of visceral organs is a recognized condition of Reiter's Syndrome. To our knowledge, however, involvement of the colon, as it is seen in other rheumatoid-like processes mostly caused by vasculitis, has not been described before. We present the case of a patient with incomplete Reiter's Syndrome with arthritis, circinate balanitis and psoriasilike lesions of skin and nails who developed ischemic colitis. Angiographic features point to vasculitis as a potential cause, although this could not be proved. It is possible but, as we believe, unlikely that simultaneously administered steroid treatment may have contributed to the development of the lesions.
