Summary
Mohs micrographic surgery effectively treats subungual squamous cell carcinoma, preserving digits. This outpatient procedure achieved complete tumor clearance with no recurrence in a mean follow-up of 3.1 years.
Area of Science:
- Dermatology
- Oncology
- Surgical Pathology
Background:
- Subungual squamous cell carcinoma is a rare but potentially aggressive malignancy.
- Treatment often involves amputation, leading to functional deficits.
- Mohs micrographic surgery offers a potential limb-sparing alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of Mohs micrographic surgery for subungual squamous cell carcinoma.
- To assess oncologic outcomes and functional preservation of the digits.
Main Methods:
- Retrospective analysis of eight patients treated with Mohs micrographic surgery.
- Outpatient procedures performed under local anesthesia.
- Wounds allowed to heal by secondary intention with distal phalanx preservation.
Main Results:
- Complete tumor clearance achieved in all cases after a median of 3 procedures.
- Mean follow-up of 3.1 years showed no evidence of recurrence.
- Involved digits remained functional post-treatment.
Conclusions:
- Mohs micrographic surgery is a viable and effective treatment for subungual squamous cell carcinoma.
- This technique allows for successful tumor removal while preserving digit function and avoiding amputation.
- Further studies are warranted to confirm these findings in larger cohorts.
