A 20-year-old man presented with low back pain and was found to have a paraspinal mass by radiology. The diagnosis of the biopsy was not conclusive due to prominent crush artifact. The peripheral blood showed no evidence of leukemia or dysplasia, but bone marrow biopsy revealed acute myeloid leukemia. The patient received several cycles of chemotherapy for acute leukemia. Two years later, he developed inguinal lymphadenopathy. A biopsy is depicted in Figs. 21.1 and 21.2.
