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]
Ewing sarcoma is a type of pediatric cancer [5] that forms in bone or soft tissue. [1] Symptoms may include swelling and pain at the site of the tumor, fever , and a bone fracture . [ 2 ] The most common areas where it begins are the legs, pelvis , and chest wall. [ 4 ]
A computed tomography scan of the same patient's abdomen pre-operation reveals a large retroperitoneal soft-tissue mass. There are long hyperdense opacities that resemble fetal bones. Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of its twin. An early ...
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.
The soft fibroma (fibroma molle) or fibroma with a shaft (acrochordon, skin tag, fibroma pendulans) consist of many loosely connected cells and less fibroid tissue. [3] It mostly appears at the neck, armpits or groin. The photo shows a soft fibroma of the eyelid.
[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

The differential diagnosis includes many tumoral and nontumoral pathologies. A main concern is to differentiate early myositis ossificans from malignant soft-tissue tumors, and the latter is suggested by a fast-growing process. If clinical or sonographic findings are dubious and extraosseous sarcoma is suspected, biopsy should be performed.
