Abstract
We herein describe a case of herpes zoster localized to the oral mucosa of an odontogenic infection patient with ulcerative colitis. A 21-year-old man with ulcerative colitis was referred to the Department of Dentistry and Oral Surgery at Toho Hospital for complications of pyrexia and swelling of the right cheek. Antibiotics were instilled for the diagnosis of the cheek phlegmon originating in the pericoronitis of the right mandibular wisdom tooth. On the third day, multiple erosions appeared in hard palate and buccal mucosa but no erosion and bleb were identified in the facial epidermis in the buccal region and anterior to the ear. Intravenous drip of antiviral drug (acyclovir) was commenced though the examination result for the varicella-zoster virus (VZV) antibody was negative. On the 11th day, inflammation and erosions in the oral cavity resolved completely and he was discharge. At the time of discharge, complement fixation reaction for the VZV antibody examination was revealed to be 256 times greater than norm.
