Using a sensitive, specific immunoprecipitation method, the biosynthesis of human skin collagenase was studied in fibroblast cultures from patients with recessive dystrophic epidermolysis bullosa. Sodium dodecyl sulfate polyacrylamide gel electrophoresis of solubilized immunoprecipitates showed two 3H-labeled procollagenase species that comigrated with those harvested from control cultures. Rec...

Acquired melanocytic lesions resembling malignant melanoma have been described in all major categories of Epidermolysis bullosa and referred to as "Epidermolysis bullosa nevi''. They easily induce to diagnostic error, although no malignant transformation has been reported. We report the development of a large acquired melanocytic nevus at a site of recurrent blisters in a 5-year-old child with ...

Epidermolysis bullosa, a group of heritable blistering disorders, shows extensive phenotypic variability due to mutations in as many as 20 distinct genes. There is no cure for this devastating group of disorders; however, a number of preclinical developments show promise, and some approaches have already reached the stage of early clinical trials. Dystrophic Epidermolysis Bullosa Research Assoc...

Epidermolysis bullosa is a rare inherited muco-cutaneous disorder that sometimes presentes with genitourinary involvement. Herein we report the case of an 11-year-old girl with a history of junctional epidermolysis bullosa who was admitted with urological symptoms. On cystoscopy, suspected bullous bladder lesions were observed. Mesonephroid, intestinal and squamous metaplasia is reported here f...

Epidermolysis bullosa (EB) is a rare disorder characterized by inherited skin adhesion defects with abnormal disruption of the epidermal-dermal junction in response to mechanical trauma. Our aim was to investigate a set of cytokine levels in serum samples from patients suffering from epidermolysis bullosa simplex (EBS), dystrophic epidermolysis bullosa (DEB), and healthy controls (HCs), explori...

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...

BACKGROUND Epidermolysis bullosa pruriginosa is a rare clinical subtype of dystrophic epidermolysis bullosa characterized by intense pruritus, secondary scratching-induced lesions, and pronounced scarring. OBSERVATIONS We describe a patient with epidermolysis bullosa pruriginosa who was misdiagnosed as having psychogenic pruritus for several years. Except for nail (toenail) dystrophy, no feat...

objective(s): epidermolysis bullosa is one of the most important series of mechano-bullous heritable skin disorders which is categorized into four major types according to the layer that bullae forms within basement membrane zone. in dystrophic form of the disease, blisters are made in the sublamina densa zone, at the level of type vii collagen protein which produce anchoring fibrils. type vii ...

epidermolysis bullosa (eb) is an inherited disorder, which is characteristically presented as skin blisters developing in response to minor injury. junctional variety of eb is also associated with enamel hypoplasia. amelogenesis imperfecta presents with abnormal formation of the enamel both in deciduous and permanent dentition. this article describes a previously unreported case of amelogenesis...
