What is congenital fibrosarcoma?
Infantile or congenital fibrosarcoma: This type of tumor is the most common soft tissue sarcoma found in children under one year of age. It presents as a rapidly growing mass at birth or shortly after. This fibrosarcoma is usually slow-growing.
What is the morphology of fibrosarcoma?
A slight degree of cellular pleomorphism exists. Most pathologists describe the histologic picture of fibrosarcoma as a herringbone pattern. It is an interlacing pattern of sheets of spindle-shaped fibroblasts in a collagen background. This pattern is very distinctive and usually confirms the diagnosis of fibrosarcoma.
Can Sarcoma be in the liver?
Sarcomas are rare malignant tumors arising from mesenchymal cells exhibiting heterogeneous histological patterns. In the liver, these tumors represent only 0.1% to 2% of primary hepatic cancer. In most patients, causative factors remain unclear. Primary symptoms are nonspecific.
Is fibrosarcoma a soft tissue sarcoma?
Fibrosarcoma is a very rare soft-tissue cancerous tumor, or sarcoma. If you develop fibrosarcoma, you have a soft tissue tumor in the tissues that wrap around your tendons, ligaments and muscles.
What is infantile Myofibromatosis?
Infantile myofibromatosis, or IM, is a rare tumor that grows in the skin, muscles, bones, and sometimes in the organs of the chest or abdomen. IM tumors are benign, which means they are not cancer and do not spread to other parts of the body.
What is an angiosarcoma?
Angiosarcoma is a rare cancer that develops in the inner lining of blood vessels and lymph vessels. This cancer can occur anywhere in the body but most often is in the skin, breast, liver and spleen.
Do Fibrosarcomas metastasize?
Fibrosarcoma is a malignant neoplasm (cancer) of mesenchymal cell origin in which histologically the predominant cells are fibroblasts that divide excessively without cellular control; they can invade local tissues and travel to distant body sites (metastasize).
What is sarcoidosis of the liver?
Sarcoidosis is a rare inflammatory disease characterized by clusters of white blood cells, called granulomas, which may form in any organ or tissue. These granulomas are damaging, and can affect the proper functioning of an involved organ.
What is hepatic angiosarcoma?
Primary hepatic angiosarcoma (PHA) is a rare hepatic tumor, originating from endothelial and fibroblastic tissue, primarily made up of vessels and composed of abundant vasculature. It represents only 0.1–2% of all primary liver malignancies [1]. PHA commonly occurs in ages from 60 to 70 years.
Does fibrosarcoma metastasize?
