A case of a patient with small cell lung cancer and right submandibular node enlargement due to granulomatous lymphadenitis is presented. Diagnostic procedures included: biopsy of the cervical node, transmission computed tomography of the chest, bronchoscopic examination and biopsy of the pulmonary lesion. The patient underwent 111In-octreotide scintigraphy (whole body and single photon emission tomography) which revealed both lesions. We conclude that granulomatous lesions are to be considered as a possible cause of false positive results, when octreotide scintigraphy is used to evaluate distant metastases in patients with known cancer.
本文报告一例小细胞肺癌患者，其右下颌下淋巴结肿大是由肉芽肿性淋巴结炎所致。诊断程序包括：颈部淋巴结活检、胸部透射计算机断层扫描、支气管镜检查及肺部病变活检。该患者接受了铟-111奥曲肽闪烁扫描（全身及单光子发射断层扫描），结果显示了两处病变。我们得出结论，当使用奥曲肽闪烁扫描评估已知癌症患者的远处转移时，肉芽肿性病变应被视为假阳性结果的可能原因。
