Re: Actinic Keratosis

Dr. Ian Montgomery at the University of Glasgow, Scotland asks:

>>Actinic keratosis: Fix and process as usual for skin or does this condition 
require a more specialized technique. My usual for skin would be formalin 
then alcohol / amyl acetate dehydration.<<

Usual technique for skin would work fine for most actinic keratoses and 
seborrheic keratoses. Occasionally actinic keratoses are covered by a thick 
mass of keratin ("cutaneous horn") which if it doesn't fall off in the course 
of grossing the specimen may render microtomy somewhat more challenging.
