Presentation of extramedullary acute myelogenous leukemia as bilateral testicular masses: response to non-myeloablative allogeneic transplantation.

We present an unusual case of extramedullary acute myelogenous leukemia (AML) presenting as bilateral testicular masses. The patient subsequently developed diffuse skin lesions and bone marrow involvement. Although he had only a partial response to intensive chemotherapy, the patient obtained a complete remission after non-myeloablative allogeneic transplantation.
