Interpretation of Mohs micrographic frozen sections: a peer review comparison study.

The ability of the Mohs surgeon to interpret frozen sections generated during Mohs surgery has been questioned recently. In this study 1000 Mohs micrographic slides were interpreted by a Mohs surgeon and subsequently by a general pathologist. The disputed slides were then reviewed independently by two Mohs surgeons, two pathologists, and a dermatopathologist. Overall, there was a 98.9% agreement in interpretation among the Mohs surgeons, the pathologists, and the dermatopathologist. Results would indicate that a well-trained and experienced Mohs surgeon is competent to interpret slides prepared under his or her supervision during Mohs surgery.
