The complement system plays a key role in several dermatological diseases. Overactivation, deficiency, or abnormality of the control proteins are often related to a skin disease. Autoimmune mechanisms with autoantibodies and a cytotoxic effect of the complement membrane attack complex on epidermal or vascular cells can cause direct tissue damage and inflammation, e.g., in systemic lupus erythem...

Bullous pemphigoid is an autoimmune subepidermal blistering dermatosis that is uncommon in childhood. We report a case of a female infant, 3 months old, which presented clinical and laboratory data for the confirmatory diagnosis of bullous pemphigoid. The authors used immunohistochemical staining for collagen type IV that allowed the differentiation of bullous pemphigoid from other subepidermal...

BP: bullous pemphigoid DIF: direct immunofluorescence TNF-a: tumor necrosis factorealpha INTRODUCTION Up to 20% of cases of bullous pemphigoid (BP) show an atypical presentation, exhibiting localized distribution or non-bullous lesions, such as eczematous, urticarial, prurigolike, and erythema multiformelike papules and plaques. These atypical presentations can be associated with a delay in dia...

Diseases associated with immunoglobulin A (IgA) antibody include linear IgA dermatosis, IgA nephropathy, Celiac disease, Henoch-Schönlein purpura, etc. Although usually idiopathic, IgA antibody is occasionally induced by drugs (e.g., vancomycin, carbamazepine, ceftriaxone, and cyclosporine), malignancies, infections, and other causes. So far, only a few cases of IgA bullous dermatosis coexistin...

Exfoliative skin diseases are rare in neonates. When caused by coagulase-positive Staphylococcus aureus, scalded-skin diseases such as staphylococcal scalded-skin syndrome (SSSS), bullous impetigo, and staphylococcal scarlet fever may develop. These diseases might cause significant complications and mortality. SSSS is caused by staphylococcal exfoliative toxins A or B, which split the granular ...

The association of autoimmune bullous diseases (i.e., bullous pemphigoid, linear IgA disease, mucous membrane pemphigoid and IgA pemphigus) and inflammatory bowel disease, namely ulcerative colitis and Crohn's disease has formerly been reported. However, to our knowledge, we report herein the first case of lymphocytic colitis with concomitant bullous pemphigoid.

The immunobullous disorders are a group of autoimmune diseases in which components of the epidermis and basement membrane zone are targeted, resulting in the formation of cutaneous and mucosal blisters. Based on the level of blistering, the autoimmune blistering diseases may be subdivided into intraepidermal and subepidermal. An exhaustive list of immunobullous disorders is beyond the scope of ...

A patient who developed a bullous skin eruption associated with carbamazepine overdosage is described. The authors believe this previously unreported phenomenon to be of clinical importance. Carbamazepine should be considered in the differential diagnosis of drug-induced coma with associated bullous lesions.
