[Surgical treatment of basaliomas with calculated safety margin and control of the histologic borders. Experiences with 355 tumors].

An integrated concept for the surgical treatment of basal cell carcinoma is presented, which is based on individually calculated safety margins and modified microscopically controlled surgery. The individual calculation of the safety margin assumes there is a relationship between the clinically visible tumor diameter and subclinical infiltration; the calculation of the safety margin therefore is based on the size of the clinically visible portion of the basal cell carcinoma. Detection of subclinical infiltration and exclusion of the possibility of subtotal excision are ensured by routine histological control of the margins of the excised specimen. The surgical treatment of basal cell carcinoma presented in this study is considerably less time-consuming than other forms of microscopically controlled surgery. No recurrences have been observed after radical excision of basal cell carcinomas with this method.
