Melkersson-Rosenthal syndrome is the term used when there
is cheilitis (chronic swelling of the face), peripheral facial palsy, and lingua plicata (“scrotal”
tongue). Granulomatous cheilitis is a chronic swelling of the lip caused by granulomatous inflammation.
Miescher cheilitis is the term used when the granulomatous changes are confined to the lip.
Miescher cheilitis generally is regarded as a monosymptomatic form of the Melkersson-Rosenthal
syndrome, although the possibility remains that they are separate diseases.
