[Buccolinguofacial apraxia--a probably psychogenic speech and deglutition disorder].

Difficulties in swallowing and speaking may in rare cases be due to buccolinguofacial apraxia, which usually results from lesions of the frontal operculum--mostly on the left side--or of connections to and from it. Two cases with this disorder, probably due to a multiple sclerosis, are presented and the differential diagnosis is discussed.
