Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) in a two-year-old.

Streptococcal pharyngitis testing and treatment is not routinely recommended in children under the age of 3 because of the unlikely occurrence of infection and negligible risk of serious complications. However, streptococcal pharyngitis and its resulting complications are not uncommon in this age group and can have serious consequences. We report a case of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections in a 2-year-old with streptococcal pharyngitis. Testing and treatment for streptococcal pharyngitis should be strongly considered when there is evidence of infection and/or an immune-mediated streptococcal complication to prevent and/or decrease the severity of short- and long-term complications.
