From furuncle, abscess, and sebaceous, fatty and fibroid tumors.
After incision, the contents of the furuncle are rapidly scooped out with the curette (Fig. 178, A).
It is then quickly withdrawn, at the same time incising the furuncle freely down to its base.
Another method is to transfix the furuncle by passing the knife through its base and making it cut outwards through the skin.
