Soft-tissue sarcomas commonly originate in the upper body, in the shoulder or upper chest. Some symptoms are uneven posture, pain in the trapezius muscle, and cervical inflexibility [difficulty in turning the head]. [12] The most common site to which soft-tissue sarcoma spreads is the lungs. [13]
The tumors can be quite large (up to 20 cm), although most are around 5 cm. [4] A high power photomicrograph of an elastofibroma. By microscopie view, there is an admixture of heavy dense bands of collagenous tissue dissected by fat and abnormal elastic fibers. The elastic fibers are often quite large and are easily identified.
Individuals presenting with SEF tumors are 3 [1] to 87 years old [1] (median age 44.6 years [9]) with most individuals aged 30-60 years. [7] These tumors involve the lower limb and shoulder areas (28.3% of cases), trunk (18.7%), head and neck areas (11.7%), lung and its pleura (10.0%), bone (including the spinal vertebrae [6]) (10.0%), soft tissues (9.1%), upper limb and shoulder areas (7.5% ...
[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
Myxofibrosarcoma (MFS), although a rare type of tumor, is one of the most common soft tissue sarcomas, i.e. cancerous tumors, that develop in the soft tissues of elderly individuals. [1] Initially considered to be a type of histiocytoma termed fibrous histiocytoma or myxoid variant of malignant fibrous histiocytoma, [ 2 ] Angervall et al ...
Plexiform fibrohistiocytic tumor appears as a painless, slowly expanding soft tissue mass located in the dermis and subcutis. [2] The skin layer above is somewhat elevated and occasionally has a central depression. [3] The upper extremities were more commonly affected by plexiform fibrohistiocytic tumors.
The term fibromatosis refers to a group of soft tissue tumors [1] which have certain characteristics in common, including absence of cytologic and clinical malignant features, a histology consistent with proliferation of well-differentiated fibroblasts, an infiltrative growth pattern, and aggressive clinical behavior with frequent local recurrence.
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.
