SARCOMA MAXILLAE SUPERIORIS

Sarcoma of the maxilla (Sarcoma maxillae superioris) is a group of malignant, rapidly growing, and highly invasive tumors of mesenchymal origin that arise from the maxillary bone and adjacent soft tissues, characterized by destruction of bone, rapid spread to surrounding anatomical structures, and early hematogenous and lymphogenous metastasis. Sarcomas of the jaws most often originate from the medullary (bone marrow) portions of the jaw bones. Sarcomas developing from the elements of bone tumors are relatively rare.Among jaw sarcomas, spindle-cell (fusiform) and round-cell sarcomas, reticulosarcomas, chondrosarcomas, fibrosarcomas, and myxosarcomas are encountered more frequently.Sarcomas usually develop in younger patients compared to carcinomas. They are characterized by rapid growth, less pronounced inflammatory signs, and an early tendency to metastasize. Determining the stage of sarcoma development is of great diagnostic importance..
