Abstract
Three cases of laryngeal tuberculosis that were experienced in the Department of Otolaryngology, Syuto General Hospital, are reported.
Although it has been said that laryngeal tuberculosis decreased recently in number, they were still reported sometimes, and a case per 2-3 years had visited our out-patient clinic. We did not think that laryngeal tuberculosis was a very rare case.
All three cases had suffered from lung tuberculosis, but they all had been examined regulary, and they had thought that it had already been cured. But laryngeal tuberculosis had recurred due to intraductal infection.
As it is necessary to make differential diagnosis of laryngeal tuberculosis from carcinoma, histopathological examination is important.
