Isolated myeloid sarcoma is a rare extramedullary manifestation, characterized by the presenceof myeloid blasts in the body and occurring without bone marrow involvement. While the iso-lated myeloid sarcoma involvement in the nasal cavity of adults has been reported sparsely,there have been no documented cases involving children in South Korea. Given its rarity, diag-nosing isolated myeloid sarcoma is challenging without resorting to a biopsy accompanied by acomprehensive panel of immunohistochemistry. In this context, we present a case of a 5-year-old child diagnosed with isolated myeloid sarcoma situated within the right nasal cavity. Nota-bly, this case is unique as there is no evidence of bone marrow invasion or underlying hemato-logical disorders.
