Pleural effusion in hematological pathology.

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.

Eosinophilia With Hepatic Mass and Abnormal Liver Function Tests: An Unusual Presentation of Chronic Myeloid Leukemia.

Chronic myeloid leukemia (CML) is a chronic myeloproliferative neoplasm characterized by excess granulocytes at different stages of maturation and the presence of BCR-ABL1 fusion gene or Philadelphia chromosome. Absolute eosinophilia, basophilia, and monocytosis are not uncommon in CML. However, a rare entity called eosinophilic variant of CML (eoCML) can present with eosinophilia without excess neutrophils or basophils. Here, we report a rare and unusual case of eoCML presenting as a liver mass with abnormal liver function tests, which has not been reported in the literature so far.
