Usually in children 6 months to 5 years old, but can occur in adults
Fever, lymphadenopathy, nausea, irritability

Painful, erythematous gingiva and tiny (1–3 mm) coalescing vesicles progress to widespread, multiple sharply marinated ulcers
of oral mucosae and skin around mouth & lips In adults, may presents as pharyngotonsillitis Lesions heal spontaneously in 1 to 2 weeks

At jct of vermillion and skin, not on mucosa (aphthae)
Intraoral: limited to keratinized mucosa that is bound to bone → hard palate and gingiva
——
Tiny vesicles or ulcers that coalesce
Heal within 7 to 10 days
Herpetic whitlow (fingers)
Histologic examination shows multinucleated, infected epithelial cells (viral cytopathic effect)
