Pleural fluid eosinophilia is rare and is commonly considered as an indicator of good prognosis. In a series of 224 patients, pleural eosinophilia was present in four of 84 malignant cases; however, the incidence of malignancy in the presence of pleural eosinophilia was 0.40, being explained by a relatively high prevalence of malignancies in the population studied. Although pleural eosinophilia is rare in malignant effusions, it cannot be considered as indicating a good prognosis without taking into consideration the local prevalence of malignancies.
胸腔积液嗜酸性粒细胞增多症较为罕见，通常被视为预后良好的指标。在一组224例患者中，84例恶性病例中有4例出现胸腔嗜酸性粒细胞增多；然而，胸腔嗜酸性粒细胞增多情况下的恶性肿瘤发生率为0.40，这是由于所研究人群中恶性肿瘤的患病率相对较高所致。尽管胸腔嗜酸性粒细胞增多在恶性胸腔积液中很少见，但在不考虑当地恶性肿瘤患病率的情况下，不能将其视为预后良好的指标。
