[Immunohistochemical study of porokeratosis in kidney transplantation]

Six cases of disseminated actinic superficial porokeratosis are reported in kidney transplant recipients. Immunohistochemistry study showed an altered state of Langerhans cell surface markers at the level of the cutaneous lesions of porokeratosis. We can hypothesize that the alterate state of epidermal dendritic cells in porokeratosis contributes to the development of abnormal clones of keratinocytes.
