Gastrointestinal involvement complicating Stevens-Johnson syndrome.

Three cases of Stevens-Johnson syndrome with intestinal involvement are described. Two patients had esophageal involvement, the severity of which paralleled skin lesions and, in 1 case, probably contributed to death. Dysphagia and bleeding were manifestations. The third patient was unique and had gastric, small and large bowel involvement with sparing of other mucosae. Cramps, severe exudative diarrhea, and bleeding were major clinical features. Unusual histologic features included sloughing of cells into the gland lumina of intestinal mucosa.
