Four cases of intractable recurrent oropharygeal ulceration having difficulty in diagnosing

Abstract

We experienced 4 cases of intractable recurrent oropharyngeal ulceration (erosion and aphthous ulcer), diagnosed other diseases by these later course. Two cases were pemphigoid, and the others were Behcet's Disease. At first all cases were not diagnosed by the clinical test, biopsy and blood test. Some of the systematic diseases are complicated firstly with such oropharyngeal symptoms. In such cases, it takes times to reveal other organ complication or positive immunology histological test, which would be helped to be correctly diagnosed. We should confirm other symptoms than oropharyngeal region, and request meticulous examinations to the related clinics when we experience intractable recurrent oropharyngeal ulceration, especially in recrudescence.
