Oral mucous membrane pemphigoid: A clinical study of 100 low-risk cases

Abstract

OBJECTIVE: To analyze the severity of the oral lesions in low-risk oral mucous membrane pemphigoid (OMMP) measured according to the size of the bullous areas and the number of simultaneously affected oral locations.

MATERIAL AND METHODS: A total of 100 cases of low-risk OMMP were studied. The symptoms and location of OMMP in the oral cavity were analyzed. The bullous areas were measured, establishing three grades according to the greatest bullous lesion size (grade 1: < 3 cm in size; grade 2: 3-6 cm; and grade 3: > 6 cm).

RESULTS: The mean age of the patients was 66.07 ± 13.55 years, with a clear predominance of females (84%). Desquamative gingivitis was the most common presentation (97%). A single oral location was found in 67% of the cases, two in 18% and three in 15%. The most common presentation corresponded to grade 1 (the greatest bullous lesion size < 3 cm; 51.6% of the cases).

CONCLUSIONS: Most cases of low-risk OMMP are restricted to a single site in the oral cavity, the gingiva being the most common location-the predominant grade corresponding to the greatest bullous lesion size < 3 cm.
