Extramedullary Hematopoiesis: An Unusual Finding in Subdural Hematomas
Figure 1
EMH within subdural hematoma. (a) Clusters of small round cells with hyperchromatic round nuclei and scant cytoplasm in a background of connective tissue with acute and chronic hemorrhage (H and E ×400). (b) The small round cells show strong immunoreactivity for glycophorin A, a marker for erythroblastic line cells (glycophorin A ×400).
