Skin blistering disorders result from damaged proteins involved in the dermal-epidermal adhesion. The damage is either caused by genetically induced defects or autoantibodies targeting those proteins. In hereditary epidermolysis bullosa (EB) skin pathogenetically linked to genetic deficiency of distinct epidermis junction, but circulating against these have also been identified EB patients. So ...

Epidermolysis bullosa (EB) is an inherited blistering disorder characterized by the fragility of the skin and mucous membranes. Extracutaneous manifestations can be associated. We report a unique concomitant occurrence of EB and hypertrophic pyloric stenosis in a newborn.

Clinical record An anxious 50-year-old woman presented with recurrence of a painful, well demarcated violaceous eruption with erythematous margins and large areas of blistering on her ankles and dorsa of her feet (Box 1, A). She had an erythematous desquamating rash on her hands, forearms and periorbital skin, with surrounding hyperpigmentation (Box 1, B). There were no signs of chronic liver d...

Subepidermal blistering associated with the human skin diseases bullous pemphigoid and herpes gestationis has been thought to be an IgG autoantibody-mediated process; however, previous attempts to demonstrate the pathogenicity of patient autoantibodies have been unsuccessful. An immunodominant and potentially pathogenic epitope associated with these blistering diseases has recently been mapped ...

BACKGROUND Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance. In Saudi Arabia, consanguinity of parents is common and consequently the occurrence of familial disease, including that of the skin, is not uncommon. METHODS To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical phot...

BACKGROUND Extraintestinal manifestations of Crohn's disease may involve the skin, the eyes, the genital mucosa, and the joints. Dermatoses associated with Crohn's disease include neutrophilic dermatoses, erythema nodosum, granulomatous dermatitis, blistering dermatoses, and non-specific skin manifestations. Cutaneous Crohn's disease is characterized by skin non-caseating epithelioid granulomat...

Autoantibodies in the skin and sera of patients with epidermolysis bullosa acquisita bind to a large matrix molecule within the lamina densa region of skin basement membrane. At the site of these immune complexes, the epidermis separates from the dermis, which creates a subepidermal blister just below the lamina densa. The target molecule for the autoantibodies is in close apposition to fibrone...

Autoimmune bullous diseases are associated with autoimmunity against structural components maintaining cell-cell and cell matrix adhesion in the skin and mucous membranes. Pemphigus diseases are characterized by autoantibodies against the intercellular junctions and intraepithelial blisters. In pemphigoid diseases and epidermolysis bullosa acquisita, sub-epidermal blistering is associated with ...

Aplasia cutis congenita (ACC) is a rare congenital defect in which localized or widespread areas of the skin are absent at birth. In the majority of cases, it is limited to the scalp especially on the vertex although other areas of the body may also be involved. Other congenital malformations can be associated with ACC. We present herein the case of a new born male with unilateral absence of sk...
