Palmoplantar lichen planus is a localized and uncommon variant of lichen planus which is mostly resistant to treatment. Our purpose was to discuss all treatment modalities proposed and tested for palmoplantar lichen planus in the literature. A systematic review of the literature was conducted to evaluate evidence regarding all treatment modalities proposed and tested for palmoplantar lichen pla...

Clinical Description The patient complained of multiple non-healing sores on his chest and back for 2 years. He had been taking traditional medications for more than 30 years for rheumatism and asthma. He had sought treatment from other clinics previously, and was treated with cryotherapy and excision of some of the chest lesions. These had unfortunately recurred. Clinically, he had numerous er...

Despite, the fact that palmoplantar pustulosis is still widely known by this name, it is currently regarded as a disease distinct from psoriasis. The real cause is still unknown. Septic foci have been blamed, but their removal may not cure eruptions. A case series of de novo occurrence of palmoplantar pustulosis induced by tumor necrosis factor–alpha antagonist therapy has been reported. It has...

introduction:   palmoplantar psoriasis could hardly be differentiated from chronic tylotic eczema both clinically and histologically. the most commonly used therapeutic options for palmoplantar psoriasis are long-term therapy with topical corticosteroids and local puva. frequently, it is a recalcitrant disease. we investigated the efficacy and tolerability of the combination of topical calcipot...

e investigated whether or not the topographic regulation of melanocyte differentiation is determined by mesenchymal–epithelial interactions via fibroblast-derived factors. The melanocyte density in palmoplantar human skin (i.e., skin on the palms and the soles) is five times lower than that found in nonpalmoplantar sites. Palmoplantar fibroblasts significantly suppressed the growth and pigmenta...

Circumscribed palmoplantar hypokeratosis is a recently recognized dermatosis and rarely reported. It was first described in 2002 and is characterized by localized loss of the horny layer in the palmoplantar area. This dermatosis is clinically presented with a sharply circumscribed, reddish and asymptomatic plaque with slightly depressed surface localized on the palms or the soles. The clinical ...

Brunauer-Fuhs-Siemens palmoplantar keratoderma, commonly known as striate palmoplantar keratoderma, is a rare, autosomally inherited disease of linear hyperkeratosis in which patient usually presents with conspicuous longitudinal hyperkeratosis on volar surface of hands and feet. Mutations in 3 genes namely desmoglein 1, desmoplakin and keratin 1, have been identified and held responsible for t...

We investigated whether or not the topographic regulation of melanocyte differentiation is determined by mesenchymal-epithelial interactions via fibroblast-derived factors. The melanocyte density in palmoplantar human skin (i.e., skin on the palms and the soles) is five times lower than that found in nonpalmoplantar sites. Palmoplantar fibroblasts significantly suppressed the growth and pigment...

In this study, a possible new syndrome affecting 18 members of a family spanning 4 generations is described. The main features include palmoplantar hyperkeratosis, proportionate short stature, facial dysmorphism, clinodactyly, epilepsy, deafness, and hypodontia. This syndrome is inherited in an autosomal dominant manner with a high degree of penetrance but variable expressivity. This syndrome d...

Aquaporin-5 (AQP-5) is a water-transporting protein expressed in mammal sweat glands. It has been reported that the expression of AQP-5 is involved in sweating of mice, rats, and horses. However, the physiological function of human AQP-5 is still uncertain. In this report, we examined the expression pattern of AQP-5 in the skin lesions of palmoplantar hyperhidrosis in patients with Nagashima-ty...
