A 51-year-old male with a history of chronic myelomonocytic leukemia-2 (CMML-2) presented with fatigue, night sweats, dyspnea, and right-sided chest pain exacerbated by deep breath. Computed tomography scan demonstrated right-sided pleural effusion with atelectasis. Pleural fluid cytology showed reactive mesothelial cells mixed with atypical cells [Figure 1]. The immunostains are performed using the SCIP approach. [1] The atypical cells were immunoreactive for vimentin, CD68, and CD163, while non-immunoreactive for cytokeratin, calretinin, BerEP4, and MOC31.
