A unique leukoencephalopathy accompanied by palmoplantar pustulosis with identical pathological feature of helper T cell accumulation

ABSTRACT

@#Palmoplantar pustulosis is a chronic inflammatory skin disease involving the palms and soles where mild accumulation of helper T cells and neutrophils in the dermis histologically are observed. Leukoencephalopathy is a brain disease affecting white matter but is rarely accompanied by skin lesion. Here we report a unique case of leukoencephalopathy accompanied by palmoplantar pustulosis with identical pathological feature of helper T cell accumulation in both the brain and skin, suggesting a possible link in the pathogenesis.
