METHODS: A 70-year-old male patient presented with chronic cough and sputum. He had symptoms for 5 years and described shortness of breath on exertion for the previous 3 years. He had a 60 packs/year smoking history. Computerized tomography of the thorax revealed an 11-mm nodule in the right lung lower lobe superior segment and a 7-mm nodule in the right lung lower lobe poster basal segment. Those two nodules were resected by means of right thoracoscopic surgery. Pathological evaluation revealed a squamous cell carcinoma and PLCH.
CONCLUSIONS: Coexistent squamous cell carcinoma and PLCH suggest possible association between PLCH and lung cancer.
方法:一名70岁男性患者,表现为慢性咳嗽和痰。他有5年的症状,并描述了前3年劳累时呼吸急促。他有60包/年的吸烟史。胸部计算机断层扫描显示右肺下叶上段有11毫米结节,右肺下叶基底段有7毫米结节。通过右胸腔镜手术切除了这两个结节。病理评估显示鳞状细胞癌和PLCH。
结论:鳞状细胞癌和PLCH共存提示PLCH与肺癌之间可能存在关联。
