肺的类癌(即支气管类癌)是较罕见的肿瘤,约占肺内所有肿瘤的5％以下,其中嗜酸细胞性类癌更为少见。本文报告一例经组化及电镜证实的肺嗜酸细胞性类癌,并对其形态特点及组织来源加以讨论。病例报告一、临床病史及所见患者女性35岁,反复咳嗽;间歇性咯血22年,每年约1～2次,每次持续3～4天,咯血量约200～300毫升。最近两次大咯血,量约500ml左右,并伴发热及胸痛。胸部X线检查 Lung carcinoid (ie, bronchial carcinoid) is a rare tumor that accounts for less than 5% of all tumors in the lung, with eosinophilic carcinoids being even rarer. This article reports a case of pulmonary eosinophil carcinoid confirmed by histochemistry and electron microscopy, and discusses its morphological features and tissue sources. Case report I. Clinical history and findings The patient was female 35 years old and had repeated coughing; intermittent hemoptysis was 22 years, about 1 or 2 times a year, each lasting 3 to 4 days, and the hemoptysis was about 200-300 ml. The two most recent hemoptysis, the amount of about 500ml, accompanied by fever and chest pain. Chest X-ray examination
