The solid malignant tumor of undifferentiated myeloid cells with extramedullary infiltration is known as myeloid sarcoma (MS), which is uncommon in occurrence. Other names for MS include myeloblastoma, extramedullary myeloid cell tumor, and granulocytic sarcoma. Lymph nodes, skin, and bones are the most frequent sites, while the orbits and central nervous system are less frequently affected. Comprehensive research on this condition has been hindered by the rarity of MS in pediatric populations. The main objective of this paper was to provide a case report of bilateral mandibular MS diagnosed in an 8-year-old female child.
