Аннотация
BACKGROUND: Malakoplakia is a very rare benign granulomatous disease, which can invade multiple organ systems, and is often related to bacterial infection and weak immunity. It is rarely occurred in the larynx, once this happens, the patient would complain of cough, hoarseness, dysphagia, and even dyspnea.
METHODS: We reported a case of malakoplakia of larynx. The patient complained of hoarseness and cough. Her lesion was located in the right false vocal cord. six case reports of malacoplakia in larynx were compiled from the literature and integrated with this case report.
RESULTS: After excising the tumor, the symptoms of the patient with cough, hoarseness and dysphagia were improved, and there was no recurrence during 1-year follow-up. The postoperative pathological diagnosis is malakoplakia. We found that malacoplakia is more commonly located in the supraglottic region, and we speculate that there may be a relationship between larynx-associated lymphoid tissue (LALT) and laryngeal malakoplakia. The effect of surgical treatment for laryngeal malacoplakia is satisfactory.
CONCLUSION: Malakoplakia of the larynx is rare. Bacterial infection, immune deficiency, and the distribution of LALT may be related to the pathogenesis and supraglottic localization of malakoplakia. The symptoms are related to the location and size of the mass and may be serious and fatal. Surgery is an important treatment for preserving laryngeal function and low recurrence rate.
