Isolated extramedullary relapse (IEMR) is a pattern of acute myeloid leukemia (AML) relapse post-allogeneic bone marrow transplantation (alloBMT). Less is known about IEMR post-autologous BMT (autoBMT) and about factors associated with IEMR. We report a case of a woman with M4 AML who experienced IEMR post-autoBMT and review the related literature. Seventy-two alloBMT and 3 autoBMT patients, including ours, were identified. The review suggests that an M2 or M4 French-American-British (FAB) phenotype, intermediate cytogenetic risk group, and chromosome 8 abnormalities are more frequently associated with the occurrence of IEMR. IEMR occurs earlier in autoBMT than in alloBMT. Combined treatment with radiation and high-dose chemotherapy may be effective. When we searched the European Bone Marrow Transplant Registry (EBMTR) database, we found the incidence of IEMR to be statistically greater in alloBMT than in autoBMT (11% vs. 6%; P = 0.02), but no correlations have been found with the conditioning transplant regimen used. A closer follow-up, including body and central nervous system scan, should be considered in patients who are undergoing BMT presenting with several IEMR-associated factors.
