Along with the condroid element and immature mesenchymal tisssue, a cyst lined with columnar epithelium can be seen. So it is more close to adenochondroma/ mixed mesenchymoma rather than Chondroid Hamartoma.

seems like a hamartoma

no ectoderm , the neck and the age, i think it the hamartoma

I recognize mature cartilage, tubules, glands, etc

mature teratoma

some hamartoma

It does not have ectoderm component. I think it should be harmatoma.
