    Abstract

    Aims: To analyse the outcome of small margin (up to 2mm) excision of primary clinically well-defined peri-ocular basal cell carcinomas (BCCs).

    Methods: Retrospective evaluation of 90 well-demarcated primary basal cell carcinomas having a minimum follow-up of 36 months. All patients underwent excision of the tumour with maximum margins of 2mm. Resulting defects were, if possible, closed directly. Reconstruction of defects requiring flaps or grafts was delayed until receipt of the histological report which was obtained in all cases.

    Results: One-stage excision and direct closure was performed in 67 patients (74.4%). In 23 patients (25.6%) excision was performed on one day and reconstruction was done four days later, after receipt of the histopathology report. Histological assessment confirmed complete excision after the first excision in 78 (86.7%) rising to 83 (92.2%) after 2 excisions. The mean follow-up was 47.5 + 9.1 months. Of the 12 cases with incompletely excised lesions, seven of the patients chose not to have any more surgery and only one of these recurred. There were two other recurrences, and in both of them the lesion had initially been reported as completely excised. Overall the recurrence rate in our study was 3.3% (n=3).

    Conclusions: Our recurrence rate compares well with published results following conventional excision of BCCs. In the absence of availability of Mohs surgery, well demarcated nodular basal cell carcinomas can be safely excised using smaller margins than conventionally practised.
