Diagram of our traditional technique of sectioning of tissue after excision of skin tumors. Typically, sections A, B, and C are examined by frozen section. Thus, the possibility exists for tumor involvement of margins in sections D and E.

Diagram showing sectioning of tissue for our current technique of peripheral tissue examination for malignant lesions of the skin. If tumor approaches the depths of cuts A through G, a section of tissue is obtained from the depths of the excisional site for clearance. Thus, all margins are examined.
