1. Liposarcoma

   Liposarcomas are the most common subtype of soft tissue sarcomas, accounting for at least 20% of all sarcomas in adults. Soft tissue sarcomas are rare neoplasms with over 150 different histological subtypes or forms. Liposarcomas arise from the precursor lipoblasts of the adipocytes (i.e. fat cells) in adipose (i.e. fat) tissues. Adipose tissues are distributed throughout the body, including such sites as the deep and more superficial layers of subcutaneous tissues as well as in less surgically accessible sites like the retroperitoneum (i.e. space behind the abdominal cavity) and visceral fat inside the abdominal cavity.All liposarcomas consist of at least some cells that bear a resemblance to fat cells when examined for their histopathologic appearances under a microscope. However, the liposarcomas do have several forms based on differences in their clinical presentations (e.g. ages, gender preferences, sites of tumors, signs, and symptoms), severities (i.e. potential to invade local tissues, recur after surgical removal, and metastasize to distal tissues), genetic abnormalities, prognoses, and preferred treatment regimens. The World Health Organization in 2020 reclassified liposarcomas into five more or less distinct forms: 1) atypical lipomatous tumor/well-differentiated liposarcoma (WD-LPS); 2) dedifferentiated liposarcoma (DD-LPS); 3) myxoid liposarcoma; 4) pleomorphic liposarcoma; and 5) myxoid pleomorphic liposarcoma. (Pleomorphic indicates the presence of cells that have abnormal and often large variations in their size and shape and/or the size and shape of their nuclei.) While liposarcoma forms are classified as being aggressive and malignant or, in the case of the atypical lipomatous tumor/well-differentiated liposarcoma, as relatively non-aggressive and benign, all five liposarcoma forms can infiltrate locally to injure nearby tissues and organs, occur in surgically inaccessible sites adjacent to vital organs (e.g. the retroperitoneum), recur after surgical removal, and progress to life-threatening diseases. Studies to date find that all five liposarcoma forms, while usually treatable at least initially by surgical resection, are often only marginally responsive to currently used chemotherapy and radiotherapy regimens. The liposarcomas require a wide range of further studies to determine their responsiveness to various radiotherapy, chemotherapy, and more novel treatment regimens as used individually and in various combinations that would include, where possible, surgical removal.

1. liposarcoma

   Liposarcoma is a rare type of cancer that begins in the fat cells. It is considered a type of soft tissue sarcoma, which refers to cancers that begin in the muscles, fats, tendons, and other soft tissues. Liposarcoma can occur anywhere in the body but commonly affects the limbs or the abdomen. The exact cause of liposarcoma is unknown, but it usually affects adults, with varying symptoms depending on its location in the body. Treatment typically involves surgery to remove the tumor, often in combination with radiation therapy or chemotherapy.

1. Liposarcoma

   Liposarcoma is a malignant tumor that arises in fat cells in deep soft tissue, such as that inside the thigh or in the retroperitoneum. They are typically large bulky tumors which tend to have multiple smaller satellites extending beyond the main confines of the tumor. Liposarcomas, like all sarcomas, are rare.

1. Liposarcoma

   A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (From Dorland, 27th ed; Stedman, 25th ed)
