Wow! Desmoplastic ameloblastoma is a rare variant of an already very, very rare tumor! I was diagnosed with the unicystic variant both times.

If (when) it comes back, I highly recommend getting genetic testing of the tumor to see if there is targeted therapy available. I'm not telling you to do the targeted therapy, just that it's important to know whether it is a viable option. After that you, your son and your doctors need to find the best choices for your (his) particular situation.

My personal concerns about resection are largely about long-term or permanent loss of function both from a structural perspective and from a functionality perspective (permanent nerve damage).
