Reactive nodular and diffuse histiocytic proliferations of mesothelial and non-mesothelial lined sites have been sporadically reported in the literature. However, there is no cytologic literature describing this process. We report a case of reactive histiocytic proliferation mimicking a metastatic signet ring adenocarcinoma in pleural fluid from a 33-year-old white male. Ancillary studies such as immunohistochemistry should be used to elucidate the cell of origin and avoid diagnostic errors.
间皮和非间皮衬里部位的反应性结节性和弥漫性组织细胞增生在文献中已有零星报道。然而，尚无描述该过程的细胞学文献。我们报告一例33岁白人男性胸腔积液中反应性组织细胞增生酷似转移性印戒腺癌的病例。应使用免疫组织化学等辅助研究来阐明细胞来源并避免诊断错误。
