A few years ago i had a keratoacanthoma on nose. By the time it was removed it had grown to marble size. The result i needed a para flap surg. Unfortunately another has popped up on the other nostril. This time i knew what it was and saw a derm two weeks after it surfaced. The derm just took a biopsy and is rec Mohs again. I have read these things can be frozen especially if caught early ( right now its pretty small). However, the Derm wants to go w Mohs again.
