Liposarcoma is a malignant tumor of fatty tissue. Like all sarcomas, it occurs relatively rarely. The fat cells do not develop in accordance with standards, whereupon the degenerated cells develop into a tumor. Of the soft tissue sarcomas, liposarcoma is the second most common after malignant fibrous histiocytoma. Approximately 15% to 20% of soft tissue … Liposarcoma
Pathology Liposarcomas can become very large and heavy depending on their location. Tumors weighing several kilograms are not uncommon. In extreme cases, they can weigh up to 30 kg. First, a few words about the “macroscopic picture” of the tumor, i.e. how the tumor looks when seen with the naked eye. Often the tumor appears … Pathology | Liposarcoma
Can a liposarcoma metastasize? A liposarcoma can metastasize. This involves the detachment of small nests of tumor cells that can enter the bloodstream and thus be carried throughout the body and can form metastases. Liposarcomas metastasize particularly frequently into the lungs, but bones, liver, peritoneum, diaphragm and the pericardium can also be affected. Small metastases … Can a liposarcoma metastasize? | Liposarcoma
Prognosis In principle, liposarcoma is curable. However, the chances of cure depend on the size and cell structure (see pathology) of the tumor. Prognostically important is also the fact whether metastases have already formed. With “well differentiated” liposarcoma, the prognosis is usually very good. The 5-year survival rate here is 88 – 100%. This means … Prognosis | Liposarcoma
Differential diagnoses Before the diagnosis “liposarcoma” is finally made, other diagnoses must also be considered or excluded. Differential diagnoses include cellular angiofibromas, fibrous tumors, malignant schwannomas, rhabdomyosarcoma, leiomyosarcoma, and fibrous histiocytoma. Since liposarcoma itself is so rare, it is also possible that the tissue alteration is a metastasis of another tumor. All articles in this … Differential diagnoses | Liposarcoma
