this one was hard for me, but I did get right after thinking about the answers in relation to the question or the blood flow was mainly in the abdominal area not to the brain (just finished lunch) :rolleyes: ... tell me what you think...

A neoplasm arising in the location identified here (to the right: appears white with slight pink (lower right))in a 19 year old male will be most likely microscopically be characterized by the presence of:
1. megakaryocyte proliferation
2. ill-defined glands
3. sheets of plasma cells
4. osteoid deposition
5. numerous lipoblasts
Answer: #4: osteoid deposition, why? Osteosarcomas arise in the metaphyseal region of long bones and, though these neoplasms are not common, they are most likely to arise in young males. The neoplastic cells produce a pink osteoid matrix.
