[Mohs surgery in basal cell carcinoma on the face]

Abstract

Background: Basal cell carcinoma may have a locally aggressive growth pattern. This type of cancer is often located on the face and is difficult to limit clinically. Normal excision and tumour destructive treatment often lead to recurrence of the tumour. Mohs surgery is a radical technique for removing this type of lesion.

Material and method: This review article is based on articles identified by searching in PubMed with the search words "Mohs surgery" and "basal cell carcinoma", as well as personal experience.

Results: 10-15 % of all basal cell carcinomas have an aggressive growth pattern with sub clinical ramifications. Mohs surgery involves use of peroperative histological assessment of horizontal frozen sections, meaning that 100 % of the resection surface can be assessed. The objective is to reduce the risk of recurrence. Since the method saves tissue, simpler reconstruction can often be chosen. Mohs surgery is resource-demanding, but with the lower risk of recurrence, the method can be cost-effective when used for the correct indications.

Interpretation: Mohs surgery should be considered in basal cell carcinoma with an aggressive growth pattern on the face.
