Background: There have been few clinical studies of halo nevi. Objective : The purpose of this study was aimed at evaluating the clinical and histopathologic features of halo nevi and correlation between halo nevi and vitiligo. Methods : The medical records of 40 patients with halo nevi and biopsy specimens of 30 patients with halo nevi were reviewed. Results and Conclusion . 1. The ratio of male to female patients was 1:1.5. 2. The mean age of the onset was 20.1 years (male: 11.5, female : 25.9). 3. Multiple halo nevi were present in 32.5%(male : 25%, female : 37.5%). 4. The areas in which the lesions developed were head 8c neck(39.1%), back(32.8%), anterior chest(12.5%), abdomen(10.9%), groin(3.1%), and lower extremity(1.6%) in descending order. 5. The mean duration of each color in central nevus was as follows: black(2.7 years), pink(3.5 years), gray(4.9 years) 6. The most common pathology of the central nevus was intradermal(80%). 7. The halo nevi associated with vitiligo were 21 cases(52.5%) out of 40 patients. Among them, the eases with non-segmental vitiligo were 13(61.9%), the cases with segmental vitiligo were 8(38.1%). 8. Out of the 21 cases with halo nevi associated with vitiligo, the cases with halo nevi prior to vitiligo were 4(19.1%), concurrent onset 12(57.1%) and the cases with halo nevi after vitiligo were 5(23.8%).
