Abstract:Objective To analyze the clinical features and key points of laryngeal tuberculosis. Methods It was analyzed retrospectively for one case of occult laryngeal tuberculosis admitted to the Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine. The diagnosis and treatment were reviewed in combination with relevant literature. Results The Patient with recurrent sore throat and hoarseness for 10 years gradually lead to epiglottic atrophy characterized by laryngeal cartilage lesions. Tumor and autoimmune related diseases were excluded according to systematic examination, which was consistent with the characteristics of tuberculosis infection. After anti tuberculosis treatment, laryngeal mucosal lesions gradually disappeared. Conclusions The clinical manifestation of laryngeal tuberculosis is lack of specificity. It is easy to be misdiagnosed as chronic laryngitis or general bacterial infection. When young patients with recurrent sore throat and hoarseness, especially with laryngeal cartilage atrophy, the patients should be taken attention to the possibility of occult tuberculosis infection.
