Histologic control of excised tissue edges in the operative treatment of basal-cell carcinomas

The edges of 742 basal-cell carcinoma specimens were evaluated histologically to assess subclinical extension and to ensure radical excision. This procedure is considerably simpler and faster than the time-consuming standard method of microscopically controlled surgery. No recurrences of lesions excised with this method were observed during a 31/2-year observation period.
