Association of sarcoidosis and ulcerative colitis with insulin-dependent diabetes mellitus.

Ulcerative colitis and sarcoidosis are seldom associated. A 33-year-old dia betic man developed simultaneously a rectitis and a non-productive cough le ading to the diagnosis of ulcerative colitis and sarcoidosis. These diagnos es are discussed because of the possible gastrointestinal lesions from sarc oidosis or the respiratory disorders due to ulcerative colitis. Some pathop hysiological evidence can be found in this case in favor of a nonfortuitous association.
