We coil tattoo machine present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture.Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts.In this paper, we describe the clinical and pathological findings.
A brief review of published information on extramedullary hematopoiesis in subdural hematoma and Triple-barrel Curling Iron the mechanisms of pathogenesis are also discussed.While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature.Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.
