Yes. I'm mentioned before the paper that was described in had no "control" groups. Even saw a simulant in a follicular SCC today by coincidence. RAC9327. I could not seen any elastic or collagen entrapment so this might all be in situ.

I appreciate there is a single atypical mitotic figure but you should note multinucleation. When a multinucleate cell divides it's mitosis will be atypical. I reported it as a poroma. One more image here (nice coffee-bean).

RAC9306. EVG & Discussion. I thought this was a mitotic sebaceoma / sebaceous adenoma. MSH6 & PMS2 requested. So far been sceptical about clear-cut Seb Ca & MTS. See a lot mitotically active lesions erroneously called carcinoma.
