Abstract:
Halo nevus and vitiligo are known to be associated with immunologic defect that result in typical skin lesions. Random shapes and sizes of whitish patches, depending on the type, are featured in vitiligo. Halo, on the other hand, presents by surrounding the previous pigmented lesion leaving a whitish-halo-like appearance. The mechanisms underlying these entities remain to be elucidated. Various immunological responses along with biomechanical activities suggest causal relationship between the two diseases. A 6-year-old male patient was recently presented with multiple whitish patches on the various parts of the body in a Koebner phenomenon manner. A noticeable hairy congenital melanocytic nevus surrounded a well-demarcated halo of depigmentation was also observed. Clinical and pathological findings were conclusive of as halo nevus with multiple concurrent vitiligo. The pathogenic relationship between the two entities must be underlined since the nature of disease progression is associated and the respective management may also be altered accordingly.
