According to statistical studies of tuberculosis the number of patient has decreased dramatically since a new chemotherapy for this disease was introduced about 30 years ago. Tuberculosis can be found mostly in aged people nowadays. This is also true for a mortality due to tuberculosis. In recent years the occurrence of tuberculosis varied in districts; it is more frequent in the western part of Japan.Twelve cases of laryngeal tuberculosis were reported in this paper. As with tuberculosis of other organs, patients age was high compared with the previous studies. Laryngoscopic examination showed that a type of granulomatous proliferations was more frequent, hence it was difficult to differentiate them from laryngeal carcinoma. Asymptomatic tuberculosis of the lung was found in most of the patients.In order to discover laryngeal tuberculosis at an early stage and to protect spreading of the infection, it is necessary to carry out a taking of detailed anamnesis, a precise inspection, a chest X-ray and an examination of sputum, and then to make the final diagnosis with a biopsy.
