Epidermolysis bullosa (EB) is an inherited connective tissue disease causing blisters in the skin and mucosal membranes. In severe cases, EB may be associated with renal damage through several mechanisms, mainly immunological ones. The present case described a young male with dystrophic recessive EB who developed an advanced chronic renal damage secondary to tubulointerstitial nephritis that wa...

Epidermolysis bullosa naevi are large, eruptive melanocytic naevi which frequently arise in areas of former blisters in patients suffering from inherited epidermolysis bullosa. Morphologically, these naevi are similar to malignant melanoma, although so far no malignant transformation has been observed. To investigate the pathogenesis of these moles we documented their clinical evolution and the...

We describe a 49-year-old Japanese woman with cutaneous squamous cell carcinoma (SCC) developing from recessive dystrophic epidermolysis bullosa (RDEB). Interestingly, immunohistochemical staining revealed dense infiltration of CD163(+) M2 macrophages and numerous Foxp3(+) regulatory T cells (Tregs) around the tumor. Since the contribution of immunosuppressive factors (e.g. TGFβ) to the carcino...

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 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...

A 53-year-old male patient was referred for evaluation of recurrent erosions of inguinal and anogenital areas, both lower legs and the oral mucosa. In addition, almost all nails and several teeth were lacking, and the residual teeth showed enamel defects. History revealed congenital absence of skin of large parts of the lower legs and widespread blistering in early childhood. Antigen mapping sh...

epidermolysis bullosa (eb) is a group of rare inherited skin and mucous membrane disorders in which blister formation may arise spontaneously or following a minor friction. various patterns of inheritance are explicated for the disease. the disease has a profound effect on oral mucosa and may result in high prevalence of dental caries. general anesthesia is sometimes the only choice for dental ...

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...
