Temporal Bone Myeloid Sarcoma

다국어 초록 (Multilingual Abstract)

Myeloid sarcoma is a rare condition that’s caused by the aggregation of immature myeloid cells in leukemic patients.
Myeloid sarcoma occurring in the temporal bone more frequently involves the mastoid bone than is the case for metastatic
lesions arising from non-systemic malignancies. The disease is difficult to diagnose when it presents with symptoms that
mimic otomastoiditis. However, an early diagnosis is important in order to achieve complete remission of the disease.
Magnetic resonance imaging of the temporal bone is useful for making the diagnosis of myeloid sarcoma, and especially
to evaluate the extent of disease. High-dose radio- or chemotherapies are the first-line approaches and possibly the only
approaches to achieve complete remission and to cure the disease. With the aim of improving our understanding of myeloid
sarcoma in the temporal bone, the present report describes our experience with 5 such cases and we compare the clinical
features of these 5 patients with those clinical features of patients who have metastatic lesions.
