Abstract: Isolated myeloid sarcoma is a rare extramedullary manifestation, characterized by the presence of myeloid blasts in the body and occurring without bone marrow involvement. While the isolated 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, diagnosing isolated myeloid sarcoma is challenging without resorting to a biopsy accompanied by a comprehensive panel of immunohistochemistry. In this context, we present a case of a 5-yearold child diagnosed with isolated myeloid sarcoma situated within the right nasal cavity. Notably, this case is unique as there is no evidence of bone marrow invasion or underlying hematological disorders.
