Fibulin-5 mutations link inherited neuropathies, age-related macular degeneration and hyperelastic skin

To identify the disease-causing gene responsible for an autosomal dominantly inherited Charcot-Marie-Tooth neuropathy subtype in a family excluded for mutations in the common Charcot-Marie-Tooth genes, we used array-based sequence capture to simultaneously analyse the disease-linked protein coding exome at chromosome 14q32. A missense mutation in fibulin-5, encoding a widely expressed constituent of the extracellular matrix that has an essential role in elastic fibre assembly and has been shown to cause cutis laxa, was detected as the only novel non-synonymous sequence variant within the disease interval. Screening of 112 index probands with unclassified Charcot-Marie-Tooth neuropathies detected two further fibulin-5 missense mutations in two families with Charcot-Marie-Tooth disease and hyperextensible skin. Since fibulin-5 mutations have been described in patients with age-related macular degeneration, an additional 300 probands with exudative age-related macular degeneration were included in this study. Two further fibulin-5 missense mutations were identified in six patients. A mild to severe peripheral neuropathy was detected in the majority of patients with age-related macular degeneration carrying mutations in fibulin-5. This study identifies fibulin-5 as a gene involved in Charcot-Marie-Tooth neuropathies and reveals heterozygous fibulin-5 mutations in 2% of our patients with age-related macular degeneration. Furthermore, it adumbrates a new syndrome by linking concurrent pathologic alterations affecting peripheral nerves, eyes and skin to mutations in the fibulin-5 gen

Confluent and reticulate papillomatosis (Gougerot-Carteaud)

A 17 year-old girl with the diagnosis of confluent and reticulate papillomatosis (CRP) is presented. Clinical and histiopathologic differential diagnostic considerations as well as the pathogenesis of CRP are discussed

Surgical treatment of CHILD nevus

We report a young girl with an unusual manifestation of CHILD syndrome in whom skin lesions showed involvement of the right side of her neck as well as symmetrically distributed ptychotropic involvement of the large body folds. Excision resulted in improvement and finally healing of skin lesions within the submammary folds, where breast reduction was also performed, whereas excision of axillary lesions and subsequent grafting with split skin turned out to be unsuccessful

Long-term follow-up and histological changes of superficial nonmelanoma skin cancers treated with topical delta-aminolevulinic acid photodynamic therapy

Objective: To investigate the immediate and longterm effects of photodynamic therapy with delta-aminolevulinic acid (ALA-PDT) on superficial basal cell carcinomas (BCC) and superficial squamous cell carcinomas (SCC)
