Fibrosarcoma
Updates to Article Attributes
Fibrosarcomas aremalignant tumortumours of fibroblast origin. They are a type of soft tissue sarcoma that can be grouped by the patient age, i.e. adult fibrosarcoma and infantile fibrosarcoma, and/or anatomical region.
Types of fibrosarcomas include, for example:
- fibrosarcoma of the breast
- fibrosarcoma of the chest wall
- fibrosarcoma of the bone
- infantile fibrosarcoma of the lung
- ovarian fibrosarcoma
Pathology
These tumors are of mesenchymal origin. On histopathology, typically these tumors are described as with 'herringbone'"herringbone" architecture. Tumors may be well differentiated-differentiated or poorly differentiated.
Radiographic Appearance
On CT, masses with similar density to muscle may indicate a fibrosarcoma. Although detectable on MRI, fibrosarcoma is currently (c.2020) not universally understood to have a distinct signature MRI appearance that is the same regardless of the anatomical region.
Treatment and prognosis
Although adult and infantile fibrosarcomas are histologically the same, the prognoses are different with children having more favorablefavourable outcomes 4.
Radiographic Appearance
On CT masses with similar density to muscle may indicate a fibrosarcoma. Although detectable on MRI, at present, as of 2020, fibrosarcoma is not universally understood to have a distinct signature MRI appearance that is the same regardless of anatomical region.
