Generally, electrodesiccation is used to treat neurofibromatosis type 1, which is the most common type of the condition. Electrodesiccation may also be used for many other skin blemishes and tumors including sun spots, skin tags, syringomas, basal cell carcinomas (skin cancer), pyogenic granulomas, cherry angiomas, and many other conditions. It is not typically used for more aggressive tumors, such as melanoma.
