[Recurrence risk of periocular basal cell carcinoma after histologically controlled excision].

The recurrence rate appears to be comparatively high; however, R1 resected BCCs were intentionally included in this study to obtain an evaluation that reflects clinical practice as realistically as possible. It is possible that the surgical procedure and/or the type of histological examination as well as the broad interpretation of the term local recurrence could be the reason for the different recurrence data in the literature. Our data indicate that the recurrence rate is not affected by the exact localization within the orbital region, but by the respective BCC subtype. As recurrences may develop years after BCC excision a long-term follow-up is strictly recommended.
