[Pemphigus vulgaris with involvement of duodenum and colon]

Pemphigus vulgaris should be numbered among the many causes of gastrointestinal hemorrhage. In our present case, the lesions of the intestinal mucosa occurred some time before those of the oral mucous membranes which finally led to the diagnosis. At the beginning of our century, the possibility of intestinal involvement in pemphigus vulgaris was well-known among dermatologists. We suggest that patients with pemphigus vulgaris should be endoscopically examined in order to confirm the clinical observations made in former times by modern scientific methods.
