Small cell lung cancer accounts for 15-20% of all lung cancers and is the most common pulmonary neuroendocrine neoplasm. Most small cell lung cancers arise from lobar or main bronchi, the most common manifestations of small cell lung cancer is a large mass centrally located within the lung parenchyma or a mediastinal mass involving the hilus. Small cell lung cancer is easily ignored by clinicians without lung parenchyma and hilus involvement. Here, we report a case of small cell lung cancer, which was misdiagnosed as the lymphoma in contrast enhanced CT and Ga-DOTA-NOC PET/CT imagings.
A 49-year-old male with chief complaint of discontinuous cough for 1 month.
Small cell lung cancer.
Radiotherapy and chemotherapy were given thereafter.
The case had multiple enlarged lymph nodes due to tumor progression.
Small cell lung cancer is a malignant and progressive disease, and easy to be ignored in clinical. The case of small cell lung cancer without parenchyma and hilus involvement has never been reported before. Here, we report it and hope it provides a differential diagnosis for clinicians in the following similar cases.
小细胞肺癌占所有肺癌的15%-20%，是最常见的肺神经内分泌肿瘤。大多数小细胞肺癌起源于叶支气管或主支气管，小细胞肺癌最常见的表现是肺实质中央的大肿块或累及肺门的纵隔肿块。无肺实质和肺门受累的小细胞肺癌很容易被临床医生忽视。在此，我们报告一例小细胞肺癌病例，在对比增强CT和Ga-DOTA-NOC PET/CT成像中被误诊为淋巴瘤。
一名49岁男性，主诉间断咳嗽1个月。
小细胞肺癌。
此后给予放疗和化疗。
该病例因肿瘤进展出现多个肿大淋巴结。
小细胞肺癌是一种恶性进展性疾病，在临床上容易被忽视。此前从未报道过无实质和肺门受累的小细胞肺癌病例。在此，我们报告该病例，希望能为临床医生在今后类似病例中提供鉴别诊断依据。
