BACKGROUND Urticarial dermatitis may represent a useful term for a subset of a reaction pattern designated most commonly as dermal hypersensitivity by pathologists. The term is not commonly used, and requires definition to determine whether it is clinically relevant. OBJECTIVES To define urticarial dermatitis and distinguish it from other urticarial reaction patterns and to review the frequen...

Bullous pemphigoid (BP) is an acquired, autoimmune, subepidermal blistering disease with subepidermal blisters that occur mainly in the elderly (1). Although some epidemiological studies have shown that the frequency of malignancies in patients with BP is spread in similar proportion throughout the population (2,3), some authors consider BP to be a paraneoplastic synBullous pemphigoid in a pati...

INTRODUCTION Anti-p200 pemphigoid is a rare autoimmune subepidermal blistering disease, first described in 1996. This disorder was initially considered as a more benign condition compared with bullous pemphigoid and epidermolysis bullosa acquisita, but in a recent series of patients, heterogeneous clinical presentations have been described, including cases with a more severe course than previou...

It has previously been reported that pemphigoid coexists with psoriasis more frequently than it could be predicted on the basis of random distribution in the general population. In this study we present three psoriatic patients who developed tense blisters, which most likely were not provoked by anti-psoriatic treatment. Diagnosis of bullous pemphigoid in these cases was established by an overl...

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 ...
