A 74 -year-old man was hospitalized for chest pain. Chest computed tomography showed a 4 × 8 cm-sized tumor pressing on the left pectoralis major muscle. Subsequent imaging showed progression of the tumor along with rib erosion and intrapleural invasion. The patient was admitted to our hospital for a follow-up examination of the tumor. Bronchoscopy results were normal. Ultrasound-guided percutaneous needle biopsy was performed. Histopathology indicated squamous cell carcinoma on the basis of the presence of keratin pearls. We therefore diagnosed the patient with squamous cell lung carcinoma fStage IIb (T3N0M0) and subsequently administered chemoradiotherapy owing to the inoperable status of the lesion. We report a case of squamous cell lung carcinoma that was difficult to differentiate from squamous cell carcinoma of the breast, along with a review of the literature.
一名74岁男性因胸痛入院。胸部计算机断层扫描显示一个4×8厘米大小的肿瘤压迫左胸大肌。后续影像学检查显示肿瘤进展，伴有肋骨侵蚀和胸膜内侵犯。该患者因肿瘤随访检查入住我院。支气管镜检查结果正常。进行了超声引导下经皮穿刺针活检。组织病理学检查因发现角化珠而提示为鳞状细胞癌。因此，我们将该患者诊断为IIb期（T3N0M0）鳞状细胞肺癌，由于病变无法手术，随后给予了放化疗。我们报告了一例难以与乳腺鳞状细胞癌鉴别的鳞状细胞肺癌病例，并对相关文献进行了综述。
