The inheritance of Olmsted syndrome that is a very rare congenital with transgredient palmoplantar keratoderma is distinguished by the presence of massive hyperkeratosis with fissured skin and periorificial chaps. It usually appears during the early life and mostly in male pateints. Herein we report a case of Olmsted syndrome which is associated with ichthyosis and somatic type of delusion duri...

Although only a small area of the body is affected in palmoplantar psoriasis or psoriasis of the palms and soles, this condition causes considerable functional impairment due to hyperkeratosis, fissures, and erythema, and occasionally inflammation and pustules. These symptoms may seriously interfere with the patient’s quality of life and may be disabling. Moreover, the lack of a standard treatm...

Palmoplantar psoriasis is a chronic disease, which is very resistant to treatment and often leads to severe disabilities. Photochemotherapy employing psoralens combined with UVA irradiation (PUVA) is a well-accepted therapy for palmoplantar psoriasis. Its topical application (bath PUVA; cream PUVA) avoids the typical side effects of orally applied psoralens. We compared the efficacy of cream PU...

BACKGROUND Palmoplantar pustular psoriasis is often recalcitrant to therapy. Here we evaluated the therapeutic effect of alitretinoin in patients with recalcitrant palmoplantar pustular psoriasis and investigated subsequent immunopathological alterations. METHODS Seven patients with palmoplantar pustular psoriasis were treated with oral alitretinoin 30 mg once daily for 12 weeks. Efficacy was...

Liposomal pegylated doxorubicin is an encapsulation form of doxorubicin, with an improved pharmacokinetic profile and the ability to selectively accumulate into tumor tissue. As a result, the tolerated dose of the drug can be increased, followed by a reduced incidence of neutropenia and cardiotoxicity in comparison to doxorubucin treatment. However, a common adverse dose-schedule limiting effec...

Keratin 9 (K9) is a type I intermediate filament protein whose expression is confined to the suprabasal layers of the palmoplantar epidermis. Although mutations in the K9 gene are known to cause epidermolytic palmoplantar keratoderma, a rare dominant-negative skin disorder, its functional significance is poorly understood. To gain insight into the physical requirement and importance of K9, we g...

Gap junctions, which mediate rapid intercellular communication, consist of connexins, small transmembrane proteins that belong to a large family of proteins found throughout the species. Mutations in the GJB2 gene, encoding Connexin 26, can cause nonsyndromic autosomal recessive or dominant hearing loss with or without skin manifestations. A 3-yr-old Korean female and her mother presented to ou...

A 5-year-old caucasian boy, born of non-consanguineous parents, was referred to the dermatology department due palmar hiperlinearity and multiple 2-3 mm hyperkeratotic circular lesions in soles (Fig. 1). The remaining physical examination unremarkable. There a family history palmoplantar hyperkeratosis mother maternal grandfather. To spare child, punch skin biopsy taken from his mother. Patholo...
