Heat shock proteins (HSPs) are proteins that are expressed under variety of stresses including pathologic conditions. How stresses affect vitiligo is not fully understood and little is known about the role of HSPs generally and Hsp70 specifically in vitiligo. The current study investigated the expression of Hsp70 in vitiliginous (32) and normal skin (10) by immunohistochemistry together with correlating this expression with the clinicopathologic parameters in the studied vitiligo group. Hsp70 was expressed in the cytoplasm of epidermis in all normal skin compared with its localization to the cytoplasm in 35.5% and to the nuclei in 64.5% of epidermis in vitiligo lesions. Intense (P < .001) and diffuse (P < .001) expression of Hsp70 was in favor of vitiligo skin compared with normal skin. Nuclear form of Hsp70 tended to be expressed in progressive forms of the disease. The percentage of Hsp70 expression tended to be decreased with the duration of the disease. From the present study, up-regulation of HSP 70, in the form of its intense and diffuse expression, may be blamed in pathogenesis of vitiligo. Nuclear localization of HSP 70 may be more important than its presence or absence, beside it may be related to progression of the disease.
