Vitiligo, naevus anaemicus and naevus depigmentosus are important clinical differentials for ash-leaf spots. Please check your email for instructions on resetting your password. Wikipedia. This result can be explained by repigmentation of vitiligo which depends on available melanocytes derived from melanocyte stem cells located in the bulge area of hair follicles.14 In addition, a statistically different frequency of poliosis observed between the two groups (P = 0.002) suggests that poliosis can be helpful in the differential diagnosis of SV from SND. Vitiligo or Nevus Depigmentosus?? Background: Melanocyte-keratinocyte transplantation procedure (MKTP) is an effective surgical technique for restoring skin pigmentation in all types of vitiligo and leukoderma patients who are unresponsive to medical and/or phototherapy treatment.

Although a biopsy may be helpful, differential diagnosis can still be difficult despite the invasive methods, because vitiligo is not always devoid of melanocytes, and because melanin pigmentation may remain for a period of time after the development of vitiligo.7 Park et al.8 investigated the usefulness of a Mexameter, a melanin pigment measuring device in the skin, for discriminating between patients with ND and vitiligo. Medical conditions similar to or like Nevus depigmentosus. Epub 2019 Aug 16. Vitiligo, naevus anaemicus and naevus depigmentosus are important clinical differentials for ash-leaf spots.

One patient was lost to follow-up. The independent sample t‐test was used to compare the vertical width of the lesion (number of involved dermatomes) between groups. The clinical features of vitiligo are similar to those of ND, but the two diseases have different treatment responses and prognoses. Young age of onset of SV has already been revealed in a previous report that 55.6% of SV patients experienced their lesion onset before the age of 15 years.10 Not surprisingly, we found that SND age of onset was much younger than SV, despite the earlier onset of SV compared with other types of vitiligo. Segmental nevus depigmentosus and segmental vitiligo showed significantly different margins (90.5% and 41.6% serrated, respectively; P < 0.001).

These data suggest that the vertical width of the lesions is greater in patients with SND than in those with SV (Fig. Regarding the facial, cervical and truncal lesions (Table 2), several vertical guidelines mentioned above divided the lesions into medial and lateral lesions (Fig. The paler area is due to the blood vessels within the area which are more sensitive to … 1b; anterior, C4–L1; posterior, C5–S1). However, we do not know the cause of this difference. Although it is possible that a higher portion of SND lesions occur at birth, we found that more than one‐third of SND lesions and approximately 30% of SV lesions appeared between 1 and 9 years old. Sterimar are ground in this Revitol scar removal. 1 It is difficult for a pathologist to establish the absolute absence of melanocytes and melanin in a skin biopsy.
