[7]: 625 [9] Fibrolipoma: Large amounts of fibrous tissue; A fibrolipoma is a lipoma with focal areas of large amounts of fibrous tissue. A sclerotic lipoma is a predominantly fibrous lesion with focal areas of fat. [12] Neural fibrolipomas are overgrowths of fibro-fatty tissue along a nerve trunk, which often leads to nerve compression. [7]: 625
It is a type of soft-tissue sarcoma. The name "synovial sarcoma" was coined early in the 20th century, as some researchers thought that the microscopic similarity of some tumors to synovium , and its propensity to arise adjacent to joints, indicated a synovial origin; however, the actual cells from which the tumor develops are unknown and not ...
Fibromas are benign tumors that are composed of fibrous or connective tissue. [1] They can grow in all organs, arising from mesenchyme tissue. The term "fibroblastic" or "fibromatous" is used to describe tumors of the fibrous connective tissue.
This group of tumors can be divided into different subsets according to their site, growth pattern, and prognosis. [ 5 ] [ 5 ] : 361 Localized/nodular TGCT (L-TGCT), sometimes referred to as “giant cell tumor of the tendon sheath” ; [ 3 ] : 100 is a common tumor that presents as a slow-growing, encapsulated, localized and limited bump, most ...
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.
It is usually used in the description of desmoplastic small round cell tumors. Neoplasia is the medical term used for both benign and malignant tumors, or any abnormal, excessive, uncoordinated, and autonomous cellular or tissue growth. Desmoplastic reaction to breast cancer. Desmoplasia refers to growth of dense connective tissue or stroma. [2]
FMTs are a heterogeneous group of soft tissue neoplasms (i.e. abnormal and excessive tissue growths). The World Health Organization (2020) defined tumors as being FMTs based on their morphology and, more importantly, newly discovered abnormalities in the expression levels of key gene products made by these tumors' neoplastic cells.

A soft-tissue sarcoma (STS) is a malignant tumor, a type of cancer, that develops in soft tissue. [1] A soft-tissue sarcoma is often a painless mass that grows slowly over months or years. They may be superficial or deep-seated. Any such unexplained mass must be diagnosed by biopsy. [2]
