Focal tumor-like splenic extramedullary hematopoiesis

Extramedullary hematopoiesis (EMH) has been reported in various organs. However, its manifestation as a focal tumor-like splenic lesion is rare. Here, we report a case of EMH in an 85-year-old female presenting as a well-defined intrasplenic mass of 12 cm on sonography and computed tomography. Splenectomy was performed under the impression of splenic tumor, and intrasplenic focal EMH was diagnosed histopathologically.
