What types of biopsies are mentioned in the chapter, and how do they differ in procedure?

The chapter mentions three types of skin biopsies: shave biopsy, punch biopsy, and excisional biopsy. A shave biopsy involves removing a top layer of a lesion, a punch biopsy removes a core from the center, and an excisional biopsy involves removing the entire lesion.

Shave biopsies are performed by shaving off the top layer of a lesion that is elevated above the skin surface. Punch biopsies involve using a tool to remove a cylindrical core of tissue from the center of the lesion. Excisional biopsies require the complete removal of the lesion along with some surrounding tissue. Each method varies in the amount of tissue removed and the technique used, with the excisional biopsy being the most extensive.
