Abstract
We herein report 5 cases that were diagnosed with acute epipharyngitis : 1 case of uncomplicated acute epipharyngitis with no evidence of infection in the oropharynx and 4 cases of acute epipharyngitis associated with oropharyngitis. All 4 cases of acute epipharyngitis associated with oropharyngitis presented with pharyngeal pain of sudden onset involving the whole throat. Bacteriological testing revealed the same bacteria that were sensitive to the same drugs in both the epipharynx and the oropharynx. These findings suggest the possibility that patients with acute epipharyngitis associated with oropharyngitis may sometimes develop an infection due to the same bacteria simultaneously in the epipharynx and oropharynx.
