Abstract

BACKGROUND:

Basal cell carcinoma (BCC) is a non-melanocytic skin tumour with a high risk of recurrence after incomplete treatment, especially the aggressive subtypes (basosquamous, micronodular and morphea BCC). The percentage of recurrence also depends on the anatomical site of the tumour. Nose-cheek fold, paranasal fold, retroauricular fold and internal canthus are considered to be critical sites.

OBJECTIVE:

The aim of this study was to report on recurrence rates for BCC treated with Mohs micrographic surgery (MMS).

MATERIAL AND METHODS:

We retrospectively studied 350 BCCs of the head region treated with MMS. Results were analysed with chi-squared test and Fisher test and were considered significant when P value was ≤0.05.

RESULTS:

In our study, the percentage of BCC recurrence rate after MMS was of 3.4% for primary BCC and 4.9% for recurrent BCC; these were similar to the recurrence rates reported in the literature.

CONCLUSIONS:

Low recurrence rate can be achieved when treated with MMS; it is the treatment of choice for many BCC of the head. Aggressive histopathological subtypes, critical head sites and recurrence after incomplete excision are the most important indications for MMS.
