Abstract：
Pulmonary nodules are commonly encountered in medical practice, necessitating thorough evaluation due to their diverse etiologies. Identifying the underlying cause is of utmost importance, particularly in patients with a history of extrapulmonary cancer, to differentiate between metastasis and other etiologies. We present a rare case of a 24-year-old male with supraglottic squamous cancer who developed multiple pulmonary nodules, which surprisingly were caused by a rare infectious agent. The patient presented with bilateral infiltrates on imaging, raising strong suspicion of metastatic disease from primary cancer. However, bronchoscopy and biopsy revealed no malignancy but confirmed the presence of Corynebacterium amycolatum, leading to a change in the treatment approach from palliative to curative. This case highlights the importance of considering other etiologies, especially infections, in patients with cancer and pulmonary nodules. Accurate diagnosis is crucial to guide appropriate management decisions and optimize patient outcomes.
摘要：
肺结节是医疗实践中常见的，由于其病因不同，因此需要进行彻底的评估。找出根本原因至关重要，特别是在有肺外癌症病史的患者中，区分转移和其他病因。我们介绍了一个罕见的病例，一个24岁的男性患有声门上鳞状细胞癌，他发展了多个肺结节，令人惊讶的是，这是由一种罕见的传染因子引起的。患者影像学表现为双侧浸润，强烈怀疑原发癌的转移性疾病。然而,支气管镜检查和活检未发现恶性肿瘤，但证实存在淀粉棒状杆菌，导致治疗方法从姑息性转变为治愈性。这个案例强调了考虑其他病因的重要性，尤其是感染,在癌症和肺结节患者中。准确的诊断对于指导适当的管理决策和优化患者预后至关重要。
