| Popis: | Introduction The incidence of laryngeal tuberculosis has increased gradually in recent years. Laryngeal tuberculosis has strong infectivity and atypical clinical manifestations. Hence, establishing the early diagnosis of laryngeal tuberculosis is considered difficult, resulting in the high rate of misdiagnosis of laryngeal tuberculosis and increased rates of tuberculosis infection. Objective This study aimed to describe a case of laryngeal tuberculosis detected using the mycobacteria gene chips technology, facilitating the early diagnosis and the treatment of laryngeal tuberculosis. Case presentation A 27-year-old woman presented with a 7-day history of hoarseness, with a normal routine blood chemistry test and chest computed tomography results. Histological analysis of the vocal cord biopsy showed granulomatous inflammation and the negative acid-fast stain test. The mycobacteria gene chips method was used to directly examine the vocal cord tissue treated with homogenate, and the Mycobacterium tuberculosis was successfully identified. Thus, the early diagnosis of laryngeal tuberculosis and the drug sensitivity of rifampin and isoniazid were confirmed. The patient recovered after undergoing a 1-year standard anti-tuberculosis therapy. Conclusions Mycobacterial identification on homogenised biopsy using the mycobacteria gene chips method significantly facilitates the early diagnosis and the treatment of tuberculosis. |
