Metastatic alveolar rhabdomyosarcoma to the bone marrow mimicking acute leukemia

摘要

ARMS may mimic acute leukemia clinically, and the neoplastic cells can resemble hematologic blasts (especially lymphoblasts). This combination can result in a misdiagnosis. In this case, the peripheral smear and the clinical picture raised several possible causes. The diagnosis required correlation of a marrow examination, immunochemistry, flow cytometry, and cytogenetics.
