IllnessPFAPA syndrome, predisposition/association; differential diagnosis

[Sanger]

Periodic fever, aphthae (stomatitis), pharyngitis, adenopathy (PFAPA) syndrome is an auto-inflammatory syndrome with the clinical signs whose initial letters make up the acronym. There is no known monogenic basis for PFAPA (also known as Marshall syndrome with periodic fever). It mostly occurs in early childhood with regularly recurring acute episodes. The periodic fever episodes in PFAPA syndrome are often indistinguishable from those in Mediterranean fever, but they often persist in the second decade of life and are also attributed to the Behcet spectrum disorders. Molecular examination of the MEFV gene and other genes associated with periodic fever, as well as close follow-up (with or without treatment) may be necessary to make the correct diagnosis.
