PFAPA is a syndrome which stands for 'periodic fevers with aphthous stomatitis, pharyngitis, and adenitis'. Essentially, it is an infectious process that involves the glands in the head and neck, including the tonsils and adenoids. When severe, tonsillectomy and adenoidectomy may have to be performed in order to debride the area of the major cause.
