Complete circumferential peripheral and deep margin assessment

CCPDMA is the acronym for "complete circumferential peripheral and deep margin assessment". It 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. Mohs surgery often requires surgical reconstruction by a plastic surgeon afterward. Surgical excision has the advantage of immediate surgical closure of the wound. 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.
