Background: Although vitiligo shows a similar clinical picture to other disorders in which patients exhibit depigmented spots, there are few reports on the differentiation of these conditions from each other. Purpose:...Background: Although vitiligo shows a similar clinical picture to other disorders in which patients exhibit depigmented spots, there are few reports on the differentiation of these conditions from each other. Purpose: We aimed to investigate the differences and similarities between vitiligo and nevus depigmentosus in children based on the clinical course and characteristics. Materials and Methods: We conducted an examination of the disease type, treatment, progress, and differentiation of 85 cases of vitiligo and nevus depigmentosus that developed before 15 years of age among patients who visited the Osaka University Department of Dermatology with a chief complaint of white patches from January 2010 to March 2017. Results: The median age at the onset of symptoms of 79 patients with vitiligo was 4.5 years and while that of 6 patients with nevus depigmentosus was 0.8 years, indicating that the onset of nevus depigmentosus occurred earlier. While vitiligo often developed in the head and neck regions, with a tendency for depigmented spots in multiple regions, nevus depigmentosus did not show this tendency in these regions. Upon performing Wood’s lamp observation in 38 cases of vitiligo, 35 cases were found to be fluorescent chalky white and in 3 cases histologically diagnosed as vitiligo, no clear fluorescent color was observed. All 6 patients diagnosed with nevus depigmentosus exhibited a non-fluorescent off-white color under a Wood’s lamp. Conclusions: This study indicates that non-invasive observation using a Wood’s lamp is useful in the differential diagnosis of pediatric leukoderma, in addition to the subsequent clinical course, such as the presence or absence of lesional repigmentation and/or enlargement.展开更多

For some patients who attend the out patients clinic concern on treatment of the vitiligo with a new formula (Oxabet) alone VS Oxabet (oxpsolaren plus betamethasone) formula plus NB. UVB311 is during a period from (Jan 2011-Jan 2013). The study sample includes different age groups of both sexes. The study revealed that the formula alone gives good results. The localized vitiligo has a good response to the formula than generalized one. The early lesions have good responses than the old ones. The continuations of applying the treatment and the follow up of the patients enhance the efficacy of the treatment.展开更多
