Three main techniques are used to excise sebaceous cysts: conventional wide excision, minimal excision, and punch biopsy excision. A new method with two steps is proposed. First, a laser is used to make a small hole for removal of the content. Then the cyst wall is removed entirely with a minimal excision about 1 month later. With this method, the cyst is completely removed with only a small scar. It offers a good alternative for eradication of uninfected cysts, especially large cysts or cysts located in areas of thick skin or cosmetic concern.
