A case of unusual herpes gingivostomatitis

We experienced an unusual case of primary herpetic gingivostomatitis having deep, beltlike ulcers developed on the upper and lower gingiva in a patient with ulcerative collitis and reported the clinical and laboratory findings of this case.Also, by peroxidase antiperoxidase method HSV antigen was obserbed in neurofibrill of submucosa. We may suggest that this finding demonstrated a neural spread of HSV through the intra-axon.
