Background: Hand and foot melanomas (HFM) have increased risk for positive margins after conventional excision (CE). Mohs micrographic surgery (MMS) may improve margin clearance prior to reconstruction. Rates of reconstruction with positive margins have not been compared after CE versus MMS for HFM.

Background: Nail unit melanoma (NUM) is increasingly treated with digit-sparing surgery, but few published case series describe Mohs micrographic surgery (MMS) for NUM.

Objective: To describe the surgical technique, local recurrence rates, and reconstruction method for a large series of NUM treated with MMS using melanoma antigen recognized by T cells-1 immunostaining.

Methods: Biopsy-proven NUM treated with MMS-melanoma antigen recognized by T cells-1 were identified from a prospectively maintained database (2008-2023).

Few studies have examined outcomes for Mohs micrographic surgery (MMS) for cutaneous squamous cell carcinoma (cSCC) in Black versus White patients. We compared time to surgery and defect sizes after MMS between Black versus White patients with cSCC. Patients with biopsy-proven cSCC treated with MMS at the Hospital of the University of Pennsylvania were identified from a prospectively maintained database (2006-2023).

Introduction: Dermoscopy is a tool that aids clinicians in the diagnosis of actinic keratosis; however, few diagnostic accuracy studies have determined its sensitivity and specificity for this diagnosis.

Objective: Determine the diagnostic accuracy of dermoscopy on actinic keratosis.

Methods: A systematic review was conducted on EMBASE, PubMed, Scopus and the Cochrane Central Registry of Controlled Trials from inception to August 2019.
