A retrospective study of 694 Basal Cell Carcinoma excisions to quantify deep margin documentation and clearance compared to histological type and surgical margin

摘要

Aims: Basal cell carcinoma (BCC) is the most common malignancy worldwide. Although rarely a risk to life, they are potentially destructive and disfiguring. Current treatment guidelines are predominantly based on low-risk BCC and make no recommendations regarding the deep excision margin. We aim to clarify the prevalence of high-risk BCC and appropriate surgical management of the deep margin.
