    Abstract:
    BACKGROUND: Nail matrix histopathologic examination is still the criterion standard to diagnose longitudinal melanonychia (LM). OBJECTIVE: To introduce modified shave surgery combined with the nail window technique for managing LM and evaluate the postoperative outcome of the procedure. METHODS: We retrospectively reviewed the medical records of 67 patients with LM who underwent shave surgery combined with the longitudinal-strip nail window technique at our institution from March 2015 to June 2018. RESULTS: Pathologic diagnosis was accessible in all cases, and 60 cases were assessable for the postoperative outcomes. A total of 45 cases (75.0%) had no postoperative nail dystrophy, and recurrence of nail pigmentation was found in only 8 cases (13.3%). LIMITATIONS: This was a retrospective study. CONCLUSION: Modified shave surgery combined with the nail window technique is the preferable management for LM cases, with limited postoperative nail dystrophy and recurrence of pigmentation.
