    图1 胸膜煤斑灶:肺表面可见圆形或类圆形黑色斑灶样病变,3~5mm,边界清晰,局部可融合成片。(掘进工作和其他井下工作38年)Fig.1 Pleural coal dust maculae: Numerous round or quasi-circular black maculae3-5 mm in diameter are widely distributed on the pleural surfac...[继续阅读]

    进入到肺内的煤尘,可以沉积在肺内支气管及其各级分支,导致管壁增厚,甚至管腔狭窄。特别是煤尘沉积于终末细支气管及其远端部分(呼吸性细支气管、肺泡管、肺泡囊和肺泡等部分),可致小气道扩张并伴有肺泡壁的破坏,形成肺气肿...[继续阅读]

    由矽结节病变继续发展而来,多由肺内矽结节的密集融合而成。镜下可见多数玻璃样变性的矽结节紧密靠拢、互相融合,但矽结节的轮廓多可辨认。有时矽结节排列稀疏,结节间为大量增生的结缔组织与沉积的煤尘。有时在融合的结节...[继续阅读]

    图184 胸膜病变:煤尘聚集在胸膜,使胸膜局部增厚。胸膜下方煤尘灶形成,似“泪滴”状分布在胸膜下方的肺组织中。(采煤、掘进、井下运输工作31年)(HE 染色)Fig.184 Pleural lesions: Moderate amount of coal dust deposits in pleura results inpleural thick...[继续阅读]

    图155 血管内瘤栓形成:肺内一些小血管扩张,其内可见恶性肿瘤细胞瘤栓形成。(与图154 同一病例)(H.E 染色)Fig.155 Carcinoma cells emboli in small blood vessels: The malignant tumor cells lodge in the dilatedsmall blood vessels. (Sample is same as Fig.154) (H.E stain)...[继续阅读]

    Coal works’ pneumoconiosis facilities the carcinogenesis,due to the similar roles of coal dusts as carcinogenic agents. Therefore,lung cancer,such as small-cellcarcinoma,adenocarcinoma,squamous cell carcinoma,adenosquamous carcinoma,and othermalignant can...[继续阅读]

    图25 结节融合型块状纤维化(同图23 肺大切片标本)。Fig.25 Nodular confluent massive fibrosis (this large slice shares the sample with Fig.23) .图26 结节融合型块状纤维化(图25 局部放大):左图显示肺内多数煤矽结核结节融合在一起,构成结节融合型块状纤...[继续阅读]

    图123 肺内典型的煤矽结核结节:结节中央为干酪样坏死和煤尘的混合,外周为胶原纤维及煤尘沉积构成“套袖样”结构,周围肺组织尘性间质纤维化和肺气肿形成。(井下采煤8年,井上其他混合工作8年)(H.E染色)Fig.123 Classic coal silicotic t...[继续阅读]

    在47 例煤工尘肺尸检标本中,有肺脏和心脏标本的共21 例,其中伴发右心室肥厚、扩张的有9 例。镜下可见,右心室心肌纤维增粗、核大深染,呈不规则形。右室心肌组织可发生局灶状坏死或纤维化、瘢痕化。伴心肌间质水肿和胶原纤维...[继续阅读]
