Management of resistant halo nevi.
|
| Abstract | BACKGROUND:
Halo nevus (HN) is a rare dermatologic disorder characterized by typical whitish rim surrounding an existing melanocytic nevus resembling halo. It is a cosmetic problem that may be linked to vitiligo, and it is advised to remove these nevi in order to avoid development of vitiligo. OBJECTIVES: The aim of the present study is to evaluate the cosmetic outcome after nevus removal and leukoderma dermabrasion with epithelial graft followed by narrow-band ultraviolet B (NB-UVB) phototherapy as management of resistant halo nevi and avoidance of development of vitiligo. PATIENTS AND METHODS: Ten patients with persisting halo nevi were selected as candidates in this study. Superficial dermabrasion was carried out using proper diamond fraises on depigmented rim and then punch biopsy probes with suitable size were used to harvest the nevus. Thiersch graft was prepared and applied on the dermabraded depigmented area. After 1 week of the procedure, patients were exposed to NB-UVB twice weekly and were followed up for 3 months. RESULTS: Repigmentation was noticed in 2 weeks and was nearly fully accomplished in all 10 patients within the 3-month period. No other vitiligo lesions developed during this period in all patients except for one case. CONCLUSION: Excision of Sutton's nevus with combined dermabrasion and Thiersch grafting followed by phototherapy is a good aesthetic maneuver in treating halo nevi and helps in avoiding further vitiligo depigmentation.
