Abstract

A brief review of some of the systemic lesions of ulcerative colitis has been made.

In 465 patients seen between 1948 and 1963 in Leeds, skin lesions occurred in 6·2%, colitic arthritis in 12·0%, sacro-iliitis in 18% and spondylitis in 6%. Eye lesions developed in 4% and liver disease in 2%.

The significance of some of these lesions has been reviewed.
