Mohs technique

Histologically controlled surgical technique to ensure removal of the tumour in sano, e.g. in basal cell carcinoma or dermatofibrosarcoma protuberans. The removed tumour is segmented and a sketch is made for topographic orientation. The corresponding segments are carefully searched histologically for existing tumor nests (frozen section). If there are residual tumours, surgery is performed on the affected side until these are also removed in healthy tissue. See also microscopically controlled surgery.
