Mesenchymal tumors are a diverse group of tumors that arise from mesenchymal tissues, which include connective tissues such as bone, cartilage, fat, and muscle. These tumors can be benign or malignant and may occur in various parts of the body. Common types include liposarcoma, osteosarcoma, and fibrosarcoma. Diagnosis typically involves imaging studies like MRI or CT scans, followed by a biopsy to confirm the tumor type. Treatment options vary based on the tumor's nature and location, often including surgery, radiation therapy, or chemotherapy. Early detection is crucial for better outcomes.
