Malignant soft tissue tumors

Although malignant soft tissue tumors are rare, they have difficulties with rapid growth, difficulty in surgical treatment, partial resistance to chemotherapy or radiotherapy, and they need to be evaluated well. It includes many subgroups and each needs to be evaluated separately. The age of the patient, the location of the tumor, and the type of tumor that has previously received radiation therapy may be helpful. liposarcomas; Adults are seen as deep and large volume. Radiologically, it can be confused with lipomas. In the biopsy, the whole mass should be tried to be sampled by taking samples from different angles instead of a single section. Lipoma-like liosarcoma=atypical lipoma It is seen in 5 types as Myxoid type: Pleomorphic type: Differentiated type: Mixed type. rhabdomyosarcoma; It is the most common YDS in childhood and adolescents and adults. There are three types: Embryonal type, Alveolar type: Pleomorphic type. Synovial Sarcoma: It is common between the ages of 15-40. The mass is deeply located, its borders are distinct and lobulated. It is the soft tissue sarcoma most confused with benign lesions. Since lymph node metastasis may be present, the ipsilateral lymph nodes (armpit-groin) must be examined. Clear-cell sarcoma (soft tissue malignant melanoma): It is a high grade (HG) sarcoma. More common between the ages of 20-40. It is a deep-seated, small-medium-sized, sensitive and painful mass that does not adhere to the skin on its surface. It is lobulated, grows very slowly, hard. Metastases occur to the lung lymph nodes and bones. Primitive Neuroectodermal Tumor (PNET-extrascleteal Ewing’s Sarcoma) Another name for primitive neuroblasts like neuroblastoma is peripheral neuroblastoma. PNET is histologically differentiated from bone Ewing’s sarcoma and constitutes the least differentiated type of the PNET spectrum. It occurs between the ages of 10-40. Alveolar Soft Part Sarcoma: It is between the ages of 15-35, and it is a rare type. It is deeply located. It grows slowly. There may be pulsation because it is rich in blood vessels. It is painless. MR image is very confused with intramuscular hemangioma. Epithelioid Sarcoma: It is between 10-40 years old and is rare. Most of the cases are in the hand and forearm, the most common malignant YDS of the hand. Regional lymph node metastases are common. Local recurrence is common. In the first operation, wide-radical margin should be provided (including amputation) and regional lymph node dissection should be performed.
