It has been reported that the freezing of melanomas triggers an immune stimulation response from the body. Adenomas of all sizes shapes and locations are history with a quick freeze, especially wonderful in our 10-20 year old patients. Pedunculated lesions anywhere are terminated with a basic freeze of the pedicle. Perianal tumors are very susceptible to liquid nitrogen spray. Eyelid tumors are nicely eliminated, but be sure to coat the eye with petrolatum ophthalmic ointment before freezing.
Most dermal lesions freeze without a problem.
Watch out to avoid mast cell tumors, but we have not had a problem with singular mast cell skin tumors that were less than 2cm in diameter. Corneal cancer lesions are scary to do, but very safe and effective. Lick granulomas have a very good elimination rate with cryotherapy. With cyclosporine and cryotherapy, German Shepherd perianal fistulas are never to be feared. Surprisingly enough, interdigital pustules from foreign body migration or allergies respond nicely to freezing.
