Legionella infection is a group of bacterial diseases caused by species of the Legionella genus, the most notable of them being Legionnaires' disease and Pontiac fever. Legionnaires' disease primarily affects the lungs, with the respiratory and gastrointestinal systems being the most commonly affected. Legionella may cause multisystem involvement, according to this study. In this report, we present a rare case of lymphadenitis caused by , aiming to raise awareness of atypical manifestations and uncommon sites of Legionella infection.
We present the case of a 43-year-old man who was admitted to the hospital for a week due to fever and enlargement of the cervical lymph nodes. He was diagnosed with lymphadenitis, which was treated with azithromycin and lymph node puncture and drainage.
For patients with Legionella lymphadenitis, multiple etiological tests should be performed as early as possible to confirm the infectious pathogen. Early intervention with appropriate intravenous antibiotics and lymph node drainage is critical to improve the cure rate.
军团菌感染是由军团菌属物种引起的一组细菌性疾病，其中最著名的是军团病和庞蒂亚克热。军团病主要影响肺部，呼吸系统和胃肠道是最常受影响的部位。根据这项研究，军团菌可能导致多系统受累。在本报告中，我们展示了一例罕见的由[此处原文缺失病原体名称]引起的淋巴结炎病例，旨在提高对军团菌感染非典型表现和罕见部位的认识。
我们报告一例43岁男性病例，因发热和颈部淋巴结肿大入院一周。他被诊断为[此处原文缺失病原体名称]淋巴结炎，接受了阿奇霉素治疗以及淋巴结穿刺引流。
对于军团菌淋巴结炎患者，应尽早进行多项病原学检查以确诊感染病原体。早期使用适当的静脉抗生素干预和淋巴结引流对于提高治愈率至关重要。
