The tangential punch biopsy [PDF]

open access: yesDermatology Online Journal, 2019
Dermatologists around the world widely utilize skin biopsies, which can be performed using shave, punch, incisional, or excisional techniques [1]. The punch biopsy allows a dermatologist to obtain a full-thickness skin sample. The post-biopsy wound heals by primary closure or second intention [2].
