case_images: 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 x400). (b) The small round cells show strong immunoreactivity for glycophorin A, a marker for erythroblastic line cells (glycophorin A x400).

case_images: Remarkably, there were numerous microscopic nodules of hyperchromatic, small, round cells scattered diffusely in the hematoma (Figure 1(a)), which were positive for glycophorin (Figure 1(b)), an erythrocyte precursor marker.
