INTRODUCTION: Acute myeloid leukemias with MLL rearrangements are frequently associated with myelomonocytic and monoblastic/monocytic morphology, with an increased risk of leukocytosis and leukostasis-related complications. Yet, little is known regarding the clinical presentation of adult AML patients with MLL translocations based on the specific translocation partner. PATIENTS AND METHODS: Two recent AML cases with t(10;11)(p12;q23) translocations are detailed, with their shared presenting symptoms highlighted, followed by a review of the current literature. RESULTS: The specific t(10;11)(p12;q23) MLL translocation is a rare recurrent translocation partner, most commonly seen in pediatric and young adult AML. A high incidence of early morbidity from leukocytosis-related complications are frequently seen, including diffuse intravascular coagulation and tumor lysis syndrome with multiorgan system failure, even without a true leukocytosis. CONCLUSION: With prompt therapy and intensive supportive care first remissions are frequently attained, however, patients have a high risk of relapse, extramedullary disease, and poor long-term outcomes.
