Dear Editor, Poikiloderma with neutropenia (PN), Clericuzio-type (OMIM #604173), is a rare autosomal recessive genodermatosis induced by biallelic mutations in the USB1-gene. PN is characterized by early-onset poikiloderma, permanent neutropenia, and recurrent sinopulmonary infections. Additionally, a broad spectrum of cutaneous and hematological complications might occur. Read More

Hereditary epidermolysis bullosa (EB) is a mechanobullous skin fragility disorder characterized by defective epithelial adhesion, leading to mechanical stress-induced skin blistering. Based on the level of tissue separation within the dermal-epidermal junction, EB is categorized into simplex (EBS), junctional (JEB), dystrophic (DEB), and Kindler syndrome. There is no cure for EB, and painful chronic cutaneous wounds are one of the major complications in recessive (RDEB) patients. Read More

Epidermolysis bullosa (EB) is a group of rare congenital genetic conditions that result in painful blistering of the skin and mucous membranes which occur with minor trauma or friction. There are many types and subtypes of EB that need to be distinguished, as the management and prognosis of each can vary significantly. We aim to perform an up-to-date literature review on congenital EB for healthcare providers in pediatrics. Read More

Poikiloderma is a skin condition that combines atrophy, telangiectasia, and macular pigment changes (hypo- as well as hyperpigmentation). It is often mistaken for mottled pigmentation by general practitioners or nondermatology specialists. Poikiloderma can be a key presenting symptom of Rothmund-Thomson syndrome (RTS), dyskeratosis congenita (DC), hereditary sclerosing poikiloderma (HSP), hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP), xeroderma pigmentosum (XP), Bloom syndrome (BS), Kindler syndrome (KS), and Clericuzio-type poikiloderma with neutropenia (PN).

Epidermolysis Bullosa (EB) is a rare group of diseases caused by genetic variants in skin structural proteins. EB is characterized by varying degrees of skin fragility, blisters and impaired wound healing, and is classified based on the ultrastructural levels of skin cleavage-simplex, junctional, dystrophic, and Kindler Syndrome. Squamous cell carcinoma (SCC) is the most severe complication and most common cause of death of patients with EB, particularly in those with recessive dystrophic Epidermolysis Bullosa (RDEB).

Background: Kindler Syndrome (KS) is a rare genodermatosis characterized by skin fragility, skin atrophy, premature aging and poikiloderma. It is caused by mutations in the FERMT1 gene, which encodes kindlin-1, a protein involved in integrin signalling and the formation of focal adhesions. Several reports have shown the presence of non-melanoma skin cancers in KS patients but a systematic study evaluating the risk of these tumors at different ages and their potential outcome has not yet been published.

Kindler syndrome (KS) is an autosomal recessive skin disorder characterized by skin blistering and photosensitivity. KS is caused by loss of function mutations in FERMT1, which encodes Kindlin-1. Kindlin-1 is a FERM domain containing adaptor protein that is found predominantly at cell-extracellular matrix adhesions where it binds to integrin β subunits and is required for efficient integrin activation.

Background: Recessive dystrophic epidermolysis bullosa (RDEB), Kindler syndrome (KS) and xeroderma pigmentosum complementation group C (XPC) are three cancer-prone genodermatoses whose causal genetic mutations cannot fully explain, on their own, the array of associated phenotypic manifestations. Recent evidence highlights the role of the stromal microenvironment in the pathology of these disorders.

Objectives: To investigate, by means of comparative gene expression analysis, the role played by dermal fibroblasts in the pathogenesis of RDEB, KS and XPC. Read More

Bart syndrome consists of aplasia cutis congenita (ACC) and dominant or recessive dystrophic epidermolysis bullosa (DEB), associated with skin fragility and nail dysplasia. ACC in DEB is thought to be caused by trauma, the most cited cause being in utero formation of bullae consequent to friction of the limbs. Epidermolysis bullosa (EB) refers to a hereditary mechanobullous disease following trauma, characterised by formation of blisters on the skin and mucous membranes. Read More
