688 Keratinocyte behaviour in normal appearing vitiligo skin

Ultraviolet radiation sensitivity in vitiligo and adjacent normal skin.

Depigmentation therapies for normal skin in vitiligo universalis.

If vitiligo involves most of the body, it might be easier to depigment the normal remaining skin rather than to attempt repigmentation. We reviewed the literature to date regarding available therapies for depigmenting the normal skin in vitiligo universalis. Our review revealed that the threshold regarding what percentage of body surface area qualifies as depigmentation is variable among practi...

Vitiligo appearing in striae distensae as a Koebner phenomenon.

Koebner phenomenon, the appearance of preexisting skin lesions following trauma to previously uninvolved skin, has been seen frequently with vitiligo. The type of trauma leading to Koebner phenomenon can vary from scratching, surgical scars, radiotherapy, burns, irritation from drug use and laser therapy. Striae distensae are a form of injury to the skin and in this particular case resulted fro...

Keratinocyte dysfunction in vitiligo epidermis: cytokine microenvironment and correlation to keratinocyte apoptosis.

Vitiligo is a skin disorder characterized by loss of functional melanocytes. Keratinocytes contribute to melanocyte homeostasis, and keratinocyte alteration may play a role in melanocyte dysfunction in vitiligo. In particular, the release of melanogenic mediators and the level of functioning keratinocytes may affect melanocyte dysfunction in vitiligo epidermis. Keratinocyte-derived mediators in...

Micropathological changes in the sub-epidermal zone of normal appearing skin in leprosy.

Leprosy is a chronic inflammatory disease caused by Mycobacterium leprae, which affects not only the peripheral nerves and skin but also various internal viscera through the hematogenous spread, especially in lepromatous cases. The micropathological changes in epidermis, nerves and skin appendages from lesioned skin reported by various authors but reports of involvement of apparently normal sit...
