浆膜被复在胸腔、腹腔、心包腔及其内脏的表面。在生理状态下,浆膜分泌少量液体起滑润作用。当肿瘤转移、炎症刺激或循环障碍等病理情况下,浆膜分泌大量液体称之为浆膜腔积液。所谓胸水、腹水和心包水。浆膜腔积液的细胞学检查不但能鉴别积液的良、恶性质,而且根据细胞形态不少病例还可推测原发灶,并能提供疗效观察的线索等。 The serosa membrane was repaired on the surface of the chest, abdomen, pericardium, and viscera. Under physiological conditions, a small amount of liquid secreted by the serosal layer acts as a lubricant. When the tumor metastasis, inflammatory stimuli or circulatory disorders and other pathological conditions, the serous membrane secretes a large amount of fluid called serous effusion. The so-called pleural effusion, ascites and pericardial water. The cytology of serous effusion can not only identify the benign and malignant properties of effusion, but also can infer the primary tumor based on many cases of cell morphology, and can provide clues for the efficacy observation.
