BACKGROUND Pachyonychia congenita (PC) is a rare autosomal dominant disease whose main clinical features include hypertrophic onychodystrophy and palmoplantar keratoderma. The new classification is based on genetic variants with mutations in keratin KRT6A, KRT6B, KRT6C, KRT16, KRT17, and an unknown mutation. Here, we present a case of PC with unusual clinical and histological features and a fav...

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...

introduction: papillon-lefèvre syndrome(pls) characterized by palmoplantar hyperkeratosis is a rare autosomal recessive genetic disorder with rapidly progressive periodontitis and premature loss of both deciduous and permanent teeth. in this study, we report the clinical and radiographic features of papillon-lefèvre syndrome in an 11- year-old girl and we also discuss the history and various th...

Unna-Thost keratoderma is an autosomal dominant inherited disorder of keratinization, with mutation in Keratin 1 gene. The eponym refers specifically to nonepidermolytic keratoderma, although the original Thost family is now known to have had epidermolytic keratoderma. The condition usually presents in the first few months of life and is usually obvious by the age of 4 years. It rarely appears ...

Papillon-Lefèvre syndrome is a rare, autosomal recessive disease comprising palmoplantar keratoderma and periodontitis. Pyogenic liver abscess is an increasingly recognized complication. We report a new case of this association and review the current literature.
