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] Treatment may include surgery, radiotherapy, chemotherapy, and targeted drug therapy. [3] Bone sarcomas are the other class of sarcomas.
The histologic appearance is non-specific and overlaps with MPNST and fibrosarcoma. H&E stain. 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, often in proximity to joint capsules and tendon sheaths. [2] It is a type of soft-tissue sarcoma.
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.
Soft tissue. Micrograph of a tendon. Hematoxylin and eosin stain. Soft tissue connects and surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes. [1][2] Soft tissue is tissue in the body that is not hardened by the processes of ...
Arthrofibrosis (from Greek: arthro- joint, fibrosis – scar tissue formation) has been described in most joints like knee, hip, ankle, foot joints, shoulder (frozen shoulder, adhesive capsulitis), elbow (stiff elbow), wrist, hand joints as well as spinal vertebrae. [1][2] It can occur after injury or surgery or may arise without an obvious cause.
The joint capsule is a soft tissue envelope that encircles the glenohumeral joint and attaches to the scapula, humerus, and head of the biceps. It is lined by a thin, smooth synovial membrane . The rotator cuff is a group of four muscles that surround the shoulder joint and contribute to the shoulder's stability.
Aggressive fibromatosis or desmoid tumor is a rare condition. Desmoid tumors are a type of fibromatosis and related to sarcoma, though without the ability to spread throughout the body (metastasize). The tumors arise from cells called fibroblasts, which are found throughout the body and provide structural support, protection to the vital organs ...
Bilateral elastofibroma dorsi in native computed tomography: left image axial in prone position (for biopsy), right image oblique coronal view. Elastofibroma dorsi is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers. [ 1 ][ 2 ] The World Health Organization, 2020, has classified elastofibroma ...
