Which tumor originates from osseous tissue?

The presence of the term "osseous tissue" in the question is crucial for identifying the tumor that originates specifically from bone tissue. Ewing's sarcoma is indeed a bone tumor, but it primarily arises from the neural crest rather than directly from bone itself. Fibrosarcoma arises from fibrous connective tissue, while chordoma develops from notochordal remnants, often affecting the spine and base of the skull, and does not have a purely osseous origin either.

Chondrosarcoma, on the other hand, arises from cartilage, which is closely associated but distinct from bone. The correct answer linked to "osseous tissue" would be Ewing’s sarcoma, as it directly involves and forms in the bone marrow, leading to complications in the skeletal system. Thus, the original answer lacks the focus on the bone characteristic of Ewing’s sarcoma compared to chondrosarcoma and the other options, which clearly do not originate from osseous tissue.
