慢性过敏性肺炎引起弥漫性肺间质纤维化的病理特征 总被引:2,自引:0,他引:2
目的 观察慢性过敏性肺炎的病理形态特征,特别是其引起的肺间质纤维化的特点,并比较其与特发性肺间质纤维化的差异和鉴别.方法 选择2000年10月至2008年1月间lO例慢性过敏性肺炎患者活检组织及临床资料,活检肺组织全部取材,石蜡包埋、HE染色.结果 10例慢性过敏性肺炎患者,男性6例、女性4例,年龄23-59岁,平均47.2岁.主要表现为慢性咳嗽,气短等,病程4个月~6年不等.7例表现为普通性问质性肺炎(UIP)样的纤维化,肺组织内斑片状纤维化,病变沿胸膜下、小叶间隔分布,同时又有细支气管周边病变.7例均有纤维母细胞灶,并可见明显的细支气管周边肺泡上皮的细支气管化生和轻度细支气管炎.3例有轻度蜂窝肺.3例为非特异性间质性肺炎(NSIP)样纤维化,表现为肺泡间隔增宽,间质纤维组织和胶原纤维增生,保留肺泡结构.伴中-重细支气管炎,肺泡间隔可见较多淋巴细胞浸润.未见蜂窝肺结构.1例可见Schaumann小体.慢性过敏性肺炎的UIP样的纤维化与特发性UIP相比,除了间质中有松散的肉芽肿和多核巨细胞以外,表现为:(1)发病年龄较轻;(2)慢性过敏性肺炎CT上病变常同时有中、上肺病变,甚至以中、上肺为主,并可见磨玻璃影和马赛克征;(3)二者病变分布不同,特发性UIP的纤维化主要分布在胸膜下和沿小叶周边分布;而慢性过敏性肺炎的UIP样的纤维化常同时累及胸膜下/小叶周边和细支气管周围(小叶中心);(4)慢性过敏性肺炎的UIP样纤维化蜂窝肺相对较轻;(5)常伴有细支气管上皮化生.慢性过敏性肺炎的NSIP样的肺间质纤维化与特发性NSIP相比,除了间质中有松散的肉芽肿和多核巨细胞以外,二者在病理形态上很难区别.结论 慢性过敏性肺炎可以引起UIP样或NSIP样的间质纤维化.按照目前过敏性肺炎的诊断标准,部分表现为NSIP样的肺间质纤维化的慢性过敏性肺炎患者,有可能被误诊为NSIP,值得注意. 相似文献

Pulmonary diseases associated with tobacco smoking are a complex group of disorders ranging from chronic obstructive pulmonary disease (COPD) to lung cancer. Interstitial lung diseases (ILDs) have only recently been linked to smoking. The ILDs related to smoking include respiratory bronchiolitis-associated interstitial lung disease, desquamative interstitial pneumonia, and pulmonary Langerhans cell histiocytosis. The relationship of smoking with each of these entities has been largely established on the weight of epidemiologic evidence. Although they have been retained as distinct and separate conditions in various classifications of interstitial lung diseases, these 3 entities share a number of clinical, radiologic, and pathologic features suggesting that they represent a spectrum of patterns of interstitial lung disease occurring in predisposed individuals who smoke. Evaluation of histologic features, particularly in surgical lung biopsy samples, is important in making the distinction between these disorders. However, even after tissue biopsy, it may sometimes be difficult to clearly separate these entities. The importance of making the distinction between them lies in the different clinical management strategies used. Further experimental evidence, including genetic information, may be important in improving our understanding of these diseases. 相似文献

In pulmonary pathology, a wide spectrum of morphological changes is related to the consequences of smoking, and recognizing them on surgical specimens and on small transbronchial biopsies represents a challenge for the pathologist. Respiratory bronchiolitis, also referred to as smoker's bronchiolitis, is a common histologic feature found in the lung tissue of cigarette smokers. When identified as the sole histopathologic finding in the clinical setting of symptomatic interstitial lung disease, a diagnosis of respiratory bronchiolitis-interstitial lung disease is made. Since smoking is recognized to cause a variety of histologic patterns encompassing respiratory bronchiolitis, respiratory bronchiolitis-interstitial lung disease, desquamative interstitial pneumonia and pulmonary Langerhans cell hystiocytosis, smoking-related interstitial lung disease may be a useful concept to keep in mind for the pathologists. The relationship of smoking with each of these entities has been largely established on the basis of epidemiologic evidence. Although they have been retained as distinct and separate conditions in various classifications of interstitial lung diseases, these entities share a number of clinical, radiologic, and pathologic features suggesting that they represent a spectrum of patterns of interstitial lung disease occurring in predisposed individuals who smoke. Evaluation of histologic features, particularly in surgical lung biopsy samples, is important in making the distinction between these disorders. However, even after tissue biopsy, it may sometimes be difficult to clearly separate these entities. Recently, respiratory bronchiolitis-interstitial lung disease with fibrosis has been described and postulated that this is a smoking-related condition distinct from fibrotic non-specific interstitial pneumonia. 相似文献

Acute interstitial pneumonia (AIP) is a rapidly progressive condition of unknown cause that occurs in a previously healthy individual and produces the histologic findings of diffuse alveolar damage. Since the term AIP was first introduced in 1986, there have been very few case reports of AIP in children. Here we present a case of AIP in a 3-yr-old girl whose other two siblings showed similar radiologic findings. The patient was confirmed to have AIP from autopsy showing histological findings of diffuse alveolar damage and proliferation of fibroblasts. Her 3-yr-old brother was also clinically and radiologically highly suspected as having AIP, and the other asymptomatic 8-yr-old sister was radiologically suspected as having AIP. 相似文献

Diffuse interstitial pulmonary fibrosis and lung cancer 总被引:1,自引:0,他引:1
Forty-two cases of lung cancer complicated with diffuse interstitial pulmonary fibrosis (DIPF) were selected from 13,056 autopsy cases. They were divided into primary (Group I and II) and secondary (Group III) DIPF, and histopathologic and clinicopathologic studies were made. The prevalence of lung cancer with primary DIPF was 17% (8/47) which was significantly (p less than 0.01) higher than that without DIPF (7% or 886/13,009). All eight cases of lung cancer in Group I and II were male, and 7 had cigarette-smoking history. The anatomical sites of lung cancer and DIPF were all peripheral in origin, and in 7 cases located primarily in the lower lobes (left:right = 6:1). Adenocarcinoma was the most common type. The study suggests that male DIPF patients with long clinical history should be followed thoroughly for lung cancer. 相似文献
