Complete circumferential peripheral and deep margin assessment

Complete circumferential peripheral and deep margin assessment (CCPDMA) is the preferred method for the removal of certain cancers, especially skin cancers.

There are two forms of CCPDMA surgery: Mohs surgery and surgical excision coupled with margin assessment. Other examples of CCPDMA are found in classical pathology textbooks as techniques of cutting surgical specimens to allow the examination of the inferior and lateral margins of typically elliptical surgical specimens.
