Periodic fever, aphthous-stomatitis, pharyngitis, adenitis (PFAPA) syndrome includes recurrent episodes of fever with aphthous-stomatitis (mouth sores) and pharyngitis (sore throat with redness and sometimes a throat that has a white covering - exudate - like that seen in a throat with streptococcal infection). PFAPA affects children in early childhood, usually starting at age two to four years. Episodes usually decrease in frequency and resolve after the age of 10 years.
