Zusammenfassung:Granulocytic sarcoma is an extramedullary tumor composed of leukemic blasts. Isolated granulocytic sarcoma has rarely been reported in children with leukemia undergoing allogeneic stem cell transplantation. We report a case of isolated granulocytic sarcoma arising from the pleura in an 11-year-old girl who was previously treated for biphenotypic leukemia with allogeneic stem cell transplantation. Complete resolution of the tumor was achieved after two inductions with MRC 12 protocol; however, she died of sepsis during the neutropenic period. The unusual presentation, immunophenotypic differences at diagnosis and relapse, and the management options are discussed.
