Melkersson-Rosenthal syndrome is a rare entity and is, in its complete pres
entation, characterized by the association of recurrent orofacial swelling,
peripheral facial palsy and plicated tongue. Clinical diagnosis of incompl
ete forms, frequently described, is based on major and minor features, curr
ently accepted by numerous clinicians. For most investigators, Miescher's g
ranulomatous macrocheilitis is a monosymptomatic form of the affection. His
topathological findings reveal non-caseating epithelioid cell granulomas, w
ith sometimes perivascular pathognomnic arrangement, which typically shows
an obliterant epithelioid lymphangitis. The etiology of the disorder is unk
nown; a possible association with Crohn's disease has been proposed, Local
or general corticosteroids therapy is usually proposed possibly with a chei
loplastic procedure.
