Abstract:
An 8-year-old boy presented with hydroa vacciniforme with recurrent oral mucosal ulcers and treatment-resistant gingivitis/periodontitis. Symptoms of oral mucosal involvement and gingivitis/periodontitis mirrored the severity of the skin lesions in sun-exposed areas. Although Epstein-Barr virus was negative in the skin lesions, Epstein-Barr virus DNA was detected in the gingival lesions when skin disease activity increased. Human herpes viruses-6 and -7 were also positive in the gingival lesions. Notably, human parvovirus B19 DNA was detected in both skin and gingival lesions. Impairment of systemic immunity was not detected. This report describes a rare case of hydroa vacciniforme with mucosal involvement and periodontal disease accompanied by multiple local virus re-activation.
