We report an unusual case of a woman with acute myeloid leukemia who showed an isolated extramedullary relapse (IEMR) in the breast following allogeneic stem cell transplantation and review the related literature. Eighty cases of IEMR following allogeneic stem cell transplantation, including our case, were identified. The review suggests that an M2 or M4 phenotype in the French-American-British classification and a favorable cytogenetic risk group are more frequently associated with the occurrence of IEMR. Combined treatment with radiation and high-dose chemotherapy may be effective.
