Melanoma may be distinguished from extramammary paget disease of the vulva by the following immunohistological features: 1. PAS _____ 2. Keratin - 3. S100 +

Neurotization of nevus occurs due to progressive loss of _____ activity and acquisition of cholinesterase activity in deeper nervelike nevus cells
