Streptococcal Pharyngitis ("strep throat")
This common childhood infection has a classic presentation of erythema of the posterior pharynx and palatal petechiae (left). A foul-smelling exudate (right) is also commonly noted.
This infection is common in infants. The white plaques do not rub off.
Tender ulcerations on the oral mucosa are surrounded by erythema.
