A skin biopsy is the surgical removal of a sample of skin. Oftentimes, a visual examination is not sufficient to diagnose your condition appropriately. Dermatologists require a sample of the skin to undergo further evaluation and reveal clues invisible to the naked eye.

Cryotherapy or cryosurgery refers to a treatment in which surface-level skin lesions are treated by freezing them with liquid nitrogen or other freezing agents.

A cyst is a benign, circular, dome-shaped sac, filled with pus, bacteria, and dead cells. Cysts can be formed on the skin, inside your organs, or tissues. Cysts may be firm or soft to touch and often stretch the adjacent and overlying skin. Cysts can grow over time and get infected, causing complications.

Electrodessication and curettage (ED&C) is a surgical technique where a skin lesion is scraped off and heat is applied to the skin surface. It is commonly used to treat pre-cancers, seborrheic keratosis, other skin disorders, or for cosmetic concerns.

Excision is the removal of damaged skin by completely cutting it out. Excisions can be performed for many reasons including removing skin cancers, for diagnostic purposes, to improve cosmetic appearance, or to relieve symptoms.
