ABSTRACT: An upper GI endoscopy was carried out in 21 patients with lichen planus. Thirteen (61.9 percent) patients had oral mucosal lesions characteristic of lichen planus. Mean duration of skin lesions was 1.9 years and that of oral mucosal lesions was 1.2 years. Commnest site of oral mucosal involvement was mucous membrane over the cheek. Upper GI endoscopy revealed mucosal abnormalities in 16 (76.2 percent) patients. The lesions were suggestive of lichen planus in 14 (66.6 percent). Associated changes were oesophagitis and gastritis. None of the 21 patients had oesophageal stricture. Musocal biopsy from the lesions in the upper GI tract in 11 patients was suggestive of lichen planus.
