debridement | removal of necrotized tissue from a wound by surgical excision, enzymes, or chemical agents |
dermabrasion | rubbing (abrasion) using wire brushes or sandpaper to mechanically scrape away (abrade) the epidermis |
fulguration | tissue destruction by means of high-frequency electric current; also called electrodesiccation |
photodynamic therapy (PDT) | procedure in which cells selectively treated with an agent called a photosensitizer are exposed to light to produce a reaction that destroys the cells |
biopsy (Bx, bx) | representative tissue sample removed from a body site for microscopic examination |
frozen section (FS) biopsy | ultrathin slice of tissue from a frozen specimen for immediate pathological examination |
needle biopsy | removal of a small tissue sample for examination using a hollow needle, usually attached to a syringe |
punch biopsy | removal of a small core of tissue using a hollow punch |
shave biopsy | removal of elevated lesions using a surgical blade |
Mohs | layers of cancer-containing skin are progressively removed and examined until only cancer-free tissue remains |
skin graft | transplantation of healthy tissue to an injured site |
allograft | transplantation of healthy tissue from one person to another person; also called homograft |
