Abstract

Myeloid sarcoma is an uncommon extramedullary tumor of immature myeloid cells or myeloblasts. It may occur alone or concurrently with an underlying hematological malignancy. Although it can develop anywhere in the body, common sites include bones, particularly the skull and vertebra, soft tissues, and lymph nodes. However, there have been few reports of myeloid sarcoma occurring in the respiratory system, especially the large airways. We describe a case of endobronchial relapse of acute myeloid leukemia in a patient who achieved complete remission after allogeneic stem cell transplantation. To our knowledge, this is the first such report in Korea.
