Extramedullary hematopoiesis (EMH) usually involves reticuloendothelial system. However, it rarely may be present in the serous body effusions. In our case, the fluid cytology of both peritoneal and pleural fluid was diagnostic of the EMH in a patient with an undiagnosed underlying etiology.

Irradiation with X-rays has been widely utilized in the clinical treatment of solid tumors and certain hematopoietic malignancies. However, this method fails to completely distinguish between malignant and normal cells. Prolonged or repeated exposure to radiation, whether due to occupational hazards or therapeutical interventions, can cause damage to normal tissues, particularly impacting the hematopoietic system.

The patient is known to have myeloproliferative disease. Non-contrast computer tomography showed a hyperdense extra-axial collection in bilateral frontoparietal regions, which was presumed to be bilateral subdural hematoma as the initial diagnosis.

Background: Extramedullary hematopoiesis (EMH) is usually seen in the reticuloendothelial system such as the spleen and liver; however, there have been rare case reports when EMH is seen in serous fluids (SFs). The aim of this study included analyzing the cytomorphological features of EMH in SFs in correlation with various clinicopathologic parameters and recognizing potential diagnostic pitfalls as well as their prognostic significance.
Methods: Clinicopathologic parameters and radiologic and pathologic information from the patients with a cytologic diagnosis of EMH were evaluated with cytology slides.

Hematopoiesis is a process by which all blood cells are formed. The mechanisms controlling it have been studied for decades. Surprisingly, while hematopoietic stem cells are among the most extensively studied stem cell types, the complete understanding of how they are regulated during development, adulthood, or in non-homeostatic conditions remains elusive.
