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 and 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 cases 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%).
