 Currently, we conduct a prospective, randomized trial comparing the outcome of surgical excision with the outcome of curettage in nodular and superficial BCCs. Larger BCCs and micronodular or sclerosing BCCs are not included in the randomized study. They are mainly operated using three-dimensional histology 3D-histology, micrographic surgery. In this observational study we measure the cosmetic result and the recurrence rate of all BCCs not included in the randomized trial.
