Zinsser-Cole-Engmann syndrome, more commonly known as Dyskeratosis Congenita, is a heritable genodermatosis having an estimated incidence of 1 in 1 million people. It is important for an oral physician to be aware of this condition as oral leukoplakia occurs in this condition as part of a classic triad along with reticulate skin pigmentation and nail dystrophy. Besides these, there may be myria...

The lesions mainly affected the shins and some occasionally appeared on the waist. They were mildly pruritic and were worse in the summer as well as being precipitated by trauma.

ISSN 0001-5555 WNT10A is a member of the wingless signalling pathway that has a fundamental role in skin and appendageal morphogenesis (1). Moreover, naturally occurring WNT10A gene mutations have been identified in the autosomal recessive human ectodermal dysplasia syndromes odonto-onycho-derm...

In dystrophic epidermolysis bullosa, the genetic defect of anchoring fibrils leads to cleavage beneath the basement membrane and its consequent loss. A 46 year-old female patient presented blisters with a pretibial distribution associated with nail dystrophy. Her two children had hyponychia and anonychia, which affected all toe nails and the thumb, forefinger and middle finger. DNA sequencing i...

However, acquired GTDN is rare, and has not been documented extensively. This study aimed to describe the clinical features of 21 patients with acquired GTND. METHODS Twenty-one patients with acquired GTND who visited Yeouido St. Mary's Ho...

Aplasia cutis congenita type VI, also known as Bart syndrome, is a rare genetic mechanobullous disorder characterized by congenital localized absence of skin, mucocutaneous blistering lesions, and nail abnormalities. We present the case of a 4-h-old male newborn who presented with complete absence of skin over the anteromedial aspect of both lower legs associated with nail dystrophy since birth...
