Practice Patterns for Mohs Surgeons of Varying Clinical Experience: A Cross-Sectional Analysis of a Medicare Claims Database.

Background: Use of Mohs micrographic surgery (MMS) is highly prevalent, but little data are available on how surgeon experience affects surgical practice patterns.

Objective: To determine differences in use of MMS among surgeons of varying experience.

Materials And Methods: This cross-sectional study sampled from clinicians billing ≥200 mean annual Mohs surgery claims from the 2012 to 2018 Medicare Public Use File.

Concordance of Squamous Cell Carcinoma Histologic Grading Among Dermatopathologists and Mohs Surgeons.

Background: Current staging systems for cutaneous squamous cell carcinoma (cSCC) incorporate histologic grade. There are no universally agreed on criteria to define differentiation for cSCC.

Objective: To determine the interrater and intrarater reliability among dermatopathologists and Mohs surgeons in grading histological differentiation for cSCC.

Defining skin cancer local recurrence.

Definitions of skin cancer recurrence are variable and nonstandardized, which can lead to inconsistent and potentially inappropriate management of tumors of uncertain recurrence status. Defining recurrence is important given the potential association with metastasis in both melanoma and nonmelanoma skin cancer. A review of the literature across multiple disciplines involved in the care of skin cancer patients reveals that although criteria for recurrence are provided in the majority of cases, most are vague and inconsistent.
