Clinical and Dermoscopic Features of Nevi in Patients with Vitiligo

The aim of the study was to display clinical and dermatoscopic features of melanocytic nevi among patients with Vitiligo.

Materials and methods: This study was conducted in 37 patients with Vitiligo (8 male and 29 female patients from 12 to 77 years of age). Clinical histories of all patients were reviewed in detail: age, sex, duration of disease, anatomic site affected, full body photometric skin examination, dermoscopy examination on the dermatoscope HEINE MINI 10X with 70% ethyl alcohol immersion and nevi assessment according to Pehamberger pattern analysis were obtained for all recruited patients.

Results: Following dermoscopic features of melanocytic nevi in Vitiligo patients were noted: hypopigmentation, depigmented globules, fragmented pigment network and vascular pattern. The most frequent dermoscopy pattern was structure less areas (74%). In a half of all nevi globules (51%) and hypo pigmented areas (47%) were seen. In 12.5% of globular nevi globules with central hypopigmentation were observed that looked like pigment circles.

Conclusion: It is important to notice that depigmentation in patients with Vitiligo can be observed not only as skin patches, but also as a dermoscopy feature in melanocytic nevi, that is not any pathology nor any sign of dysplasia but only the sign of the autoimmune reaction against the pigment.
