Involvement of palate and cheek in leprosy.

22 Cases of bacillary positive leprosy with no apparent lesion in the oral cavity, soft or hard palate were studied for any evidence of pathological involvement. Granulomata were present in 11 (65%) out of 17 cheek biopsies studied. M. leprae were identified in four specimens only. 9 specimens (64%) out of 14 palate biopsies showed definite granulomata. M. leprae were seen in six specimens.
