Granulomatous cheilitis. A review and report of a case.

The Melkersson-Rosenthal syndrome (MRS) is a rare triad of unilateral facial paralysis, facial swelling, and fissured tongue; often only two of the components are manifest. The occurrence of swollen lips together with the characteristic microscopic appearance is called granulomatous cheilitis, which many believe is the oligosymptomatic form of MRS. This article reviews the literature on granulomatous cheilitis associated with MRS. An unusual case of a swollen upper lip together with a fissured tongue, strongly indicating the oligosymptomatic manifestations of MRS, is presented.
