5-aminolevulinic acid-induced fluorescence-guided margin mapping and slow Mohs surgery for localized extramammary paget disease: A retrospective exploratory comparative study

Objective

Extramammary Paget disease (EMPD) often extends beyond its clinically visible borders, making surgical margin control difficult, particularly in anatomically sensitive regions. This retrospective exploratory study compared 5-aminolevulinic acid (5-ALA)-induced fluorescence-guided margin mapping with slow Mohs surgery for localized EMPD, with emphasis on final margin clearance, treatment-process efficiency, tissue preservation, reconstruction requirement, patient-reported satisfaction, and crude recurrence proportion.
