A myxoid liposarcoma is a malignant adipose tissue neoplasm [1] of myxoid appearance histologically.. Myxoid liposarcomas are the second-most common type of liposarcoma, representing 30–40% of all liposarcomas in the limbs, occurring most commonly in the legs, particularly the thigh, followed by the buttocks, retroperitoneum, trunk, ankle, proximal limb girdle, head and neck, and wrist.
Kaposi sarcoma often occurs in patients with acquired immune deficiency syndrome. Kaposi sarcoma, however, has different characteristics from typical soft-tissue sarcomas and is treated differently. [8] In a very small fraction of cases, sarcoma may be related to a rare inherited genetic alteration of the TP53 gene and is known as Li-Fraumeni ...
A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [1] [2] Connective tissue is a broad term that includes bone, cartilage, muscle, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues.
Liposarcomas are the most common subtype of soft tissue sarcomas, accounting for at least 20% of all sarcomas in adults. [2] 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.
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...
A synovial sarcoma (also known as malignant synovioma [1]) is a rare form of cancer which occurs primarily in the extremities of the arms or legs, ...
Epithelioid sarcoma is a slow-growing and relatively painless tumor, often resulting in a lengthy period of time between presentation and diagnosis. [8] Due to the difficulty of discerning this cancer as different from more common cancers, such as cancers of the skin (squamous cell carcinoma or basal cell carcinoma), it is often misdiagnosed, mistaken as a persistent wart or cyst.
Dermatofibrosarcoma protuberans (DFSP) [2] is a rare locally aggressive malignant cutaneous soft-tissue sarcoma. DFSP develops in the connective tissue cells in the middle layer of the skin (dermis). [3] Estimates of the overall occurrence of DFSP in the United States are 0.8 to 4.5 cases per million persons per year.
