Analysis of Pigmented Nevus Removal Techniques:

Method Name	Chemical Peel	Liquid Nitrogen Cryotherapy	Electrocautery	Fractional Laser	Surgical Excision of Pigmented Nevus
Image Example
Principle	Application of chemical solutions to cause chemical corrosion of tissue	Use of low-temperature substances like liquid nitrogen to freeze the pigmented nevus, causing tissue cell necrosis and shedding	High-frequency electric current generates heat to burn the nevus, leading to carbonization and necrosis	Stimulates deep skin collagen protein reorganization and regeneration	Surgically removes the pigmented nevus completely via an incision
Indications	Small, superficial pigmented nevi	Small, superficial pigmented nevi	Small, raised pigmented nevi	Pigmented nevi with relatively uniform color	Larger nevi or those with potential for malignant transformation
