Excellent Jerad! Thanks so much for your dedication to teaching.

Thanks for this video, great practical tips on approaching squamoproliferative lesions in superficial shaves. As a trainee it’s easy to be blasé about these specimens, but with more experience I realise how tricky they can be.

I’m about half way through and this has been great. The most difficult distinction for me is on Frozen section for excision of SCC in situ especially in these sun exposed areas. Your pace is great. Thank you for putting this together!
