Pachyonychia congenita is a rare type of ectodermal dysplasia further classified into 4 types. Cutaneous manifestations seen in most of the cases of Pachyonychia congenita include palmoplantar keratoderma, follicular hyperkeratosis, wedge shaped nails, oral leukokeratosis and woolly hair. A 25-year-old male presented to us with thickened nails and scanty scalp hair. On examination, we noticed h...

We studied three families suffering from nail abnormalities who had previously been diagnosed as pachyonychia congenita. No keratin gene mutations were detected. Sequencing of connexin 30 (GJB6 gene) in these patients identified heterozygous missense mutations G11R and A88V that are known to be associated with Clouston syndrome. This unexpected finding expands the Clouston syndrome phenotype an...

In 1906 Jadassohn and Lewandowsky described a rare genodermatoses named it pachyonychia congenita. Pachy means thick. It is group of involving keratin mutation with thickened nails variable associated findings. Pachyonychia congenita disease having four types. However, type 1 2 can be considered common among them. often mimic fungal infection as nail hyperkeratosis occur in both.

Pachyonychia congenita comprises a heterogeneous group of autosomal dominantly inherited conditions manifesting with characteristic nail thickening, palmoplantar keratoderma, follicular keratosis and oral manifestations like mucosal leukokeratosis. Less frequently epidermal cysts, hair-shaft abnormalities, natal teeth and laryngeal involvement may be seen. It is distributed almost evenly throug...

Pachyonychia congenita is a group of autosomal dominant inheritance pattern disorders characterized by hypertrophic nail dystrophy There are two main clinical subtypes: type 1 and 2. Pachyonychia congenita type 2 is readily differentiated from type 1 by multiple steatocysts and/or presence of natal teeth and can be confirmed by mutations of KRT6B and KRT17. We report the case of a 33-year-o/d f...

Successful development of siRNA therapies has significant potential for the treatment of skin conditions (alopecia, allergic skin diseases, hyperpigmentation, psoriasis, skin cancer, pachyonychia congenital) caused by aberrant gene expression. Although hypodermic needles can be used to effectively deliver siRNA through the stratum corneum, the major challenge is that this approach is painful an...

We report the case of an 11-year-old girl who presented to our multidisciplinary pain center with the chief complaint of chronic bilateral foot pain because of a rare congenital keratin disorder. This patient had been diagnosed with pachyonychia congenita, an extremely rare genetic disorder primarily affecting the skin and nails. The child had bilateral foot pain for years because of the charac...

This is a report on two unrelated male children with a stable ring chromosome of the G group, associated with severe mental retardation, an unusual facies, and pachyonychia congenita of the toe nails. The facial appearance was so strikingly similar, that the diagnosis in the second case was suspected clinically. Although there have been a number of reports of ring formation, simple deletion, or...

The International Pachyonychia Congenita Consortium (IPCC) was founded in 2004 in Park City, Utah, USA. Its goal is to find a cure for pachyonychia congenita, a rare keratinizing disorder. From February 14th–17th, 2013, the group convened in Park City for their tenth annual meeting. The 2013 meeting focused on how to best move forward with clinical trials and on learning from work in other scie...
