We describe the cytologic appearance of Pneumocystis carinii in pleural fluid of a patient with acquired immunodeficiency syndrome and a rapidly accumulating pleural effusion. The diagnosis of P carinii infection was made by examination of air-dried, Diff-Quik-stained Cytospin preparations of the pleural fluid. The diagnostic appearances of P carinii organisms stained by this method and by the Papanicolaou stain are reviewed. The unusual predominance of the trophozoite forms of the organism in this case made Diff-Quik an ideal special stain for identifying the organisms. Furthermore, this case illustrates a novel presentation of P carinii infection and suggests that P carinii should be considered an etiologic agent in the differential diagnosis of pleural effusion in an immunocompromised host.
我们描述了1例获得性免疫缺陷综合征患者胸腔积液中卡氏肺孢子虫的细胞学表现，该患者胸腔积液迅速积聚。通过对胸腔积液的空气干燥、Diff-Quik染色细胞离心涂片进行检查，确诊为卡氏肺孢子虫感染。本文回顾了用该方法染色及巴氏染色的卡氏肺孢子虫的诊断表现。该病例中该生物体滋养体形式异常占优势，使得Diff-Quik成为鉴定该生物体的理想特殊染色方法。此外，该病例说明了卡氏肺孢子虫感染的一种新表现形式，并提示在免疫功能低下宿主胸腔积液的鉴别诊断中应考虑卡氏肺孢子虫为病因。
