Articles On Leukotrichia

 Medical Definition of leukotrichia whiteness of the hair.Vitiligo is traditionally divided into two Non-segmental vitiligo (NSV) and segmental vitiligo (SV) are distinct clinical types. SV usually accompanies leukotrichia, which indicates that the condition is resistant to medical treatment and requires epidermal grafting1. In this case, caused perifollicular repigmentation in a Patient with SV and concomitant leukotropy previously unresponsive to narrow band ultraviolet B (NBUVB) phototherapy after the patient suffered an accidental burn on the denuded but uncovered area during phototherapy following an epidermal graft. A 12-year-old girl presented to our clinic with white patches that had initially developed on the right side of her trunk 2 years prior. Physical examination showed well-defined depigmented patches containing white hairs along the right T6~T12 dermatomes. White accentuation with obvious fluorescence was detected using Wood's lamp. She had received NBUVB phototherapy for 5 months without remarkable improvement. Upon consent, a suction blister epidermal graft was performed. Due to the sizeable lesion, several sessions of epidermal grafting were required.Humans have long been preoccupied with hair color and it can have a considerable psychological impact.'Leukotrichia' means 'white hair', while poliosis is the presence of white or hypopigmented hairs in a group of follicles. Leukotrichia/poliosis results from a reduction or absence of melanin in the hair follicle. The term 'canities' is usually used to indicate progressive loss of hair pigment with age.
