Liposarcomas are malignant tumours of fatty tissue and are the malignant counterpart to a benign lipoma. They are the second most common type of soft-tissue sarcoma Dr Yair Glick ◉ and Dr Gagandeep Singh et al. Retroperitoneal liposarcoma is a subtype of liposarcoma and is a malignant tumor of mesenchymal origin that may arise in any fat-containing region of the body. It is one of the most common primary retroperitoneal neoplasms MRI can have 100% sensitivity for the diagnosis of well-differentiated liposarcomas, however, has a low positive predictive value due to overlap of imaging features with benign lipoma variants 2 . Features that favor well-differentiated liposarcoma 1-3: size >10 cm 4-6. percentage fat <75%. thick or nodular (>2 mm) septa. nodular/globular areas
Primary liposarcoma of bone is an exceedingly rare neoplasm, with a prevalence of 0.03%. Because of these variations in biologic behavior, pathologic and radiologic assessment is vital to direct appropriate therapy. Imaging findings of liposarcoma are frequently characteristic Liposarcoma is a cancer that arises in fat cells in soft tissue, such as that inside the thigh or in the retroperitoneum. It is a rare type of cancer that bears a resemblance to fat cells when examined under a microscope. It is typically a large, bulky tumor, and tends to have multiple smaller satellites that extend beyond the main confines of the tumor Breast sarcoma refers to a relatively heterogenous group of rare breast tumors which can include: angiosarcoma of the breast. pleomorphic sarcoma of the breast. fibrosarcoma of the breast. myxofibrosarcoma of the breast. leiomyosarcoma of the breast. primary osteosarcoma of the breast Liposarcoma is a malignancy of fat cells (see Pediatric Liposarcoma and Liposarcoma Imaging). In adults, it is the most common soft tissue sarcoma. Liposarcoma normally appears as a slowly..
One male patient who had a final diagnosis of liposarcoma was referred to the oncology department and had 3 months of radiation therapy performed (2012.10.31~2012.12.11, total 6000 Gy). The patient was monitored for 3-6 months for any recurrence; in addition, the area surrounding the excision was monitored and checked for a range of motions Ewing sarcoma is a type of bone or soft tissue cancer that primarily occurs in children and young adults. Often found in the long bones in the body, symptoms include pain, swelling and fever. Ewing sarcoma is cancer that occurs primarily in the bone or soft tissue. While Ewing sarcoma can develop in. Epithelioid Sarcoma (ES) is a soft-tissue tumor of uncertain cellular lineage, and the most common soft-tissue malignancy of the hand and wrist in adolescents and young adults. It typically presents as a slow growing painless mass or multiple masses with or without overlying skin ulceration
. They arise from the endometrial lining or the myometrium in the uterus. Compared to the more common endometrial carcinomas, uterine sarcomas behave more aggressively and are associated with a poorer prognosis Background and objectives: Synovial sarcoma is a rare soft tissue sarcoma with poor long-term prognosis due to late recurrence and metastasis. Synovial sarcoma arises in less than 6% from the shoulder. As a result, there is limited information in the literature about synovial sarcoma of the shoulder (SSS)
Pathologically proven Ewing sarcoma. Ewing sarcoma is an aggressive bone tumor observed in the first two decades of life. Second most common malignant bone tumor in children, presenting a higher prevalence in boys than in girls (3:1 ratio). The typical clinical presentation includes: Pain and swelling at the site of the tumor Ewing sarcoma can spread from where it started to other areas, making treatment and recovery more difficult. Ewing sarcoma most often spreads to the lungs and to other bones. Long-term treatment side effects. The aggressive treatments needed to control Ewing sarcoma can cause substantial side effects, both in the short and long term Soft tissue sarcoma is a rare type of cancer that begins in the tissues that connect, support and surround other body structures. This includes muscle, fat, blood vessels, nerves, tendons and the lining of your joints. More than 50 subtypes of soft tissue sarcoma exist. Some types are more likely to affect children, while others affect mostly. AIDS-related Kaposi Sarcoma; with the two latter form being the most common and disseminated form 1.

Embryonal sarcoma is a primitive mesenchymal tumour of unknown aetiology associated with multiple genetic mutations . Also known as malignant mesenchymoma, mesenchymal sarcoma, primary sarcoma, undifferentiated sarcoma, fibromyxosarcoma, and rhabdomyosarcoma of the liver, UES is a highly aggressive tumour with a generally poor prognosis Primary effusion lymphoma (PEL) is classified as a diffuse large B cell lymphoma.It is a rare malignancy of plasmablastic cells that occurs in individuals that are infected with the Kaposi's sarcoma-associated herpesvirus (i.e. KSHV/HHV8). Plasmablasts are immature plasma cells, i.e. lymphocytes of the B-cell type that have differentiated into plasmablasts but because of their malignant nature. A bone sarcoma is a primary malignant bone tumour, a type of sarcoma that starts in the bones. This is in contrast to most bone cancers that are secondary having developed as a metastasis from another cancer. Bone sarcomas are rare, and mostly affect the legs.The other type of sarcoma is a soft-tissue sarcoma.. There are three main types of bone sarcoma based on tissue type - an osteosarcoma.

Codman triangle - a distinctive triangular form of periosteal reaction seen when an aggressive bone lesion grows faster than new periosteum can be ossified. Only the periosteum at the very margin of the lesion has time to ossify creating a triangular lip of new bone Undifferentiated pleomorphic sarcoma (UPS) is a rare type of cancer that begins mostly in the soft tissues of the body. Soft tissues connect, support and surround other body structures. UPS usually occurs in the arms or legs. Less often it can happen in the area behind the abdominal organs (retroperitoneum)
