喉頭結核の6症例

LARYNGEAL TUBERCULOSIS, A REPORT OF SIX CASES

　喉頭結核は結核化学療法のめざましい進歩と予防対策の普及により近時とみに激減している。しかし，今なお喉頭結核の症例報告は少なくない。喉頭結核が喉頭にのみ限局性に発生した場合は悪性腫瘍との鑑別がしばしば困難となり，臨床的にきわめて重要となつてくる。最近私どもの気管食道科外来で喉頭結核の6症例を経験したので国内の症例報告例もあわせて文献的に考察し報告する。

　Six cases of laryngeal tuberculosis that did not altogether conform to the classic description of this disease are reported. The ages of the patients ranged from 40 to 68.

　The laryngeal lesions in most cases simulated that of carcinoma. Tumor formation with nodular appearances in the laryngeal mucosa were the most common showings in most recent cases. Since laryngeal tuberculosis has a tendency to be asymptomatic except hoarseness, tuberculosis must be suspected whenever the latter symptom is accompanied with the presence of non-specific laryngeal lesion.

　To reach the diagnosis of laryngeal tuberculosis, the chest x-ray, sputum examination, personal and family histories will greatly enhance but, the final confirmation should rest with biopsy of the lesion.

　The treatment consisted of employing antituberculous agents. streptomycin, isoniazid and PAS, with showings of apparent improvements in the tuberculous pathology.
