Skin Biopsy

A Skin Biopsy (pronounced: /ˈskɪn ˈbaɪɒpsi/) is a medical procedure where a sample of skin tissue is removed, processed, and examined under a microscope to diagnose or rule out certain conditions.

Etymology

The term "biopsy" is derived from the Greek words "bios" (life) and "opsis" (sight), meaning "to view life." The prefix "skin" is added to specify the type of tissue being examined.

Procedure

A skin biopsy is usually performed by a dermatologist or a general practitioner. The procedure involves removing a small piece of skin using a scalpel or a special circular blade. The sample is then sent to a pathology laboratory for examination.

There are three main types of skin biopsies:

  • Punch biopsy: A circular blade is used to remove a small, round piece of skin.
  • Shave biopsy: A scalpel is used to shave off a small piece of the skin's surface.
  • Excisional biopsy: A scalpel is used to remove an entire lump or an area of abnormal skin, including a portion of normal skin down to or through the fatty layer of skin.

Indications

A skin biopsy is typically performed to diagnose various skin conditions such as skin cancer, dermatitis, psoriasis, and skin infections. It can also be used to monitor the progress of skin treatments.

Risks and Complications

Like any medical procedure, a skin biopsy carries some risks. These may include infection, scarring, and an allergic reaction to the anesthesia. It's important to discuss these risks with your healthcare provider before the procedure.
