متن کاملRepigmentation of vitiligo with autologous blister-induced epidermal grafts.
Treatment of vitiligo can sometimes be difficult and disappointing. PUVA treatments give fairly good results. However, acral regions like the hands or feet or areas over bony prominences like the elbow, are resistant to PUVA. Blister-induced epidermal grafts have been used to repigment vitiligo skin. This study was carried out on patients with vitiligo areas unresponsive to either PUVA treatmen...

The aim of this study was to investigate the incidence of hair shaft disorders in psoriatic patients and to evaluate the possibility of a correlation with scalp involvement. We examined hair from 39 psoriatic patients using scanning electron microscopy and compared it with hair from a cont...
متن کاملBehavior of Hair Follicles in Vitiligo: Clinical Presentation and Discussion

This follicular-melanin unit consists of one melanocyte for every five keratinocytes in the hair bulb as a whole; the ratio is 1:1 in the basal epithelial layer next to the dermal papilla [4]. Hair bulb melanogenic melanocytes differ from epidermal melanocytes in being larger, with longer and more exten...
