What is a term for a tumor arising from connective tissue?

A tumor that arises from connective tissue is classified as a sarcoma. Connective tissue comprises a variety of structures, including bone, cartilage, and fat, as well as other types of tissue that provide support and structure to the body. Sarcomas are malignant tumors that originate from these types of tissues, distinguishing them from carcinomas, which arise from epithelial tissues.

In the context of this question, understanding the nature of the tumors is crucial. Sarcomas can arise in different connective tissues, leading to variations such as osteosarcoma (bone) and liposarcoma (fat). The definition of sarcomas is particularly important in oncology, as they often require different treatment approaches compared to carcinomas.

The other terms provided relate to different types of tumors. A cyst typically refers to a sac-like pocket filled with fluid or semisolid material, which is not a tumor. Carcinomas are types of cancer that originate from epithelial cells, which cover the surfaces of organs and glands. Fibromas are benign tumors that originate from fibrous connective tissue, but they do not represent malignancies like sarcomas do. Hence, sarcoma is the most accurate term for a malignant tumor arising from connective tissue.
