Institutional Adherence to Current Mohs Surgery Appropriate Use Criteria With Reasons for Nonadherence and Recommendations for Future Versions.

Background: The appropriate use criteria (AUC) were established to optimize the use of Mohs micrographic surgery (MMS) and confer the highest possible clinical benefit to the patient.

Objective: We documented our adherence to AUC and review reasons for nonadherence regarding lesions classified as inappropriate, in the hopes of informing future versions of the AUC.

Materials And Methods: A retrospective review of 1,000 consecutive patients who underwent MMS at a single institution.

Management of Transected Invasive Melanoma: A Single Institution Retrospective Review.

Background: Deep transection of invasive melanoma precludes accurate measurement of Breslow depth, which may affect tumor staging.

Objective: To determine the frequency of upstaging of transected invasive melanomas after excision, characterize the impact on National Comprehensive Cancer Network (NCNN)-recommended treatment, and determine predictors of subsequent upstaging.

Materials And Methods: A retrospective review of invasive melanomas between January 2017 and December 2019 at a single institution.

Negative Predictive Value of Biopsy Margins in Keratinocyte Carcinoma: A Literature Review.

Background: Pathologists sometimes include commentary on margin involvement in shave biopsy reports of keratinocyte carcinoma (KC). This practice can lead to confusion regarding the need for further treatment. There is limited literature evaluating the reliability of reported histologic margin status in shave biopsies of KC.

Negative predictive value of biopsy margins of dysplastic nevi: A single-institution retrospective review.

Background: Biopsies of dysplastic nevi processed by bread-loafing allow for limited margin assessment; however, reported biopsy margins often influence management.

Objective: To evaluate the negative predictive value of biopsy margins of dysplastic nevi.

Methods: A retrospective search of a single academic institution's pathology database was conducted to identify all biopsy specimens of dysplastic nevi between January 1, 2015, and December 31, 2017.

A review of beta antagonist treatment for infantile hemangioma.

Infantile hemangiomas are benign vascular neoplasms of childhood that often have implications on development, cosmesis, and comfort. Traditional therapy has involved either observation or corticosteroids, depending on location and size. Recent studies have reported the successful use of beta-adrenergic antagonists in treating infantile hemangiomas.
