A middle-aged Japanese man who had been on haemodialysis treatment for diabetic nephropathy developed multiple itchy papules and nodules, which were histopathologically diagnosed as acquired perforating dermatosis. Two years later he developed oral lesions and subsequently numerous erosive plaques with necrotic crusts on the trunk and extremities. Histopathology of a papule showed a parakeratotic plug intermingled with basophilic, necrotic debris and collagen bundles, along with penetration of collagen bundles across the epidermis and subepidermal blister...

Bullous pemphigoid (BP) is considered to be a humorally mediated autoimmune disease, but autoreactive T-cells and T-regulatory cells (Tregs) have also been implicated in this disease. Tregs and the programmed death-1 (PD-1) : programmed death ligand (PD-L) pathway are both critical in terminating immune response, and elimination of either can result in breakdown of tolerance and development of autoimmunity. We report a patient with metastatic malignant melanoma (MM), who underwent pembrolizumab (anti-PD-1) therapy following unsuccessful treatment with ipilimumab [anti-cytotoxic T-lymphocyte-associated protein (CTLA)-4]...

PURPOSE: Autoimmune bullous dermatoses (AIBD) are rare, severe diseases resulting from some antibodies activity against the different adhesion structures within the skin and/or mucosa. Few studies investigated quality of life (QOL) in AIBD by generic and dermatology-specific instruments, all reporting strong impact on QOL. Recently, disease-specific measurement tools have been developed: Autoimmune Bullous Disease Quality of Life (ABQOL) and Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) questionnaires...

BACKGROUND AND OBJECTIVES: Polymorphisms in the P-glycoprotein-encoding ABCB1 gene may affect the intracellular concentration of xenobiotics, and thus contribute to the development of autoimmune diseases, including bullous pemphigoid (BP). The objective of the present study was to investigate whether there is an association between the C3435T and G2677T/A polymorphisms in the ABCB1 gene and the risk of BP in a Polish population. PATIENTS AND METHODS: The study included 71 patients with BP and 156 healthy volunteers...

The reported sensitivity and specificity of enzyme-linked immunosorbent assay (ELISA) for bullous pemphigoid (BP) diagnosis is approximately 87% and 98%, respectively. These statistics suggest that ELISA is a reliable diagnostic test; therefore, the use of ELISA for BP diagnosis has increased. We report the case of a man who was diagnosed with BP and was treated for 3 years based on a positive ELISA for IgG against BP180. After reevaluation, his revised diagnosis was not consistent with BP based on clinical presentation, histopathology, and direct immunofluorescence (DIF)...

BACKGROUND: Bullous pemphigoid (BP) is an autoimmune bullous disease of the skin characterized by subepidermal blister formation due to tissue-bound and circulating autoantibodies to the hemidesmosomal antigens BP180 and BP230. Although eosinophils and their toxic mediators are found abundantly in BP lesions, their role in blister formation has remained unclear. OBJECTIVE: To investigate the role of eosinophils in the pathogenesis of BP with a specific focus on blister formation and to define conditions inducing dermal-epidermal separation (DES)...

Immunotherapy targeting the programmed cell death 1 (PD-1) receptor has demonstrated tremendous promise in the treatment of advanced solid tumors. Dermatologic toxicities, however, are an emerging consequence of this therapy and have been clearly associated with immune checkpoint blockade antibodies. Distinctive clinical and histologic subtypes of dermatologic toxicity secondary to immunotherapy are emerging and include rare autoimmune bullous reactions (eg, bullous pemphigoid) and lichenoid eruptions. We report three patients who developed lichenoid dermatitis while receiving anti-PD-1 antibody therapy...

Checkpoint inhibitors, such as nivolumab, are revolutionary new drugs in cancer therapy. Mild dermatologic toxicities are commonly reported adverse events. Herein, we highlight the development of the autoimmune blistering condition, bullous pemphigoid (BP) in a patient undergoing treatment with nivolumab. A 60-year-old man, who was being treated with nivolumab (3mg/kg intravenously every 2 weeks) after failing chemotherapy for metastatic renal cell carcinoma, presented acutely with a blistering rash.

Dear Editor, Erythema multiforme is considered an acute skin condition, characterized by a self-limiting and sometimes recurrent course. It is regarded as a type IV hypersensitivity reaction associated with certain infections, medications, and other various triggers. Allergic contact dermatitis is in turn a delayed type of induced allergy as a result of cutaneous contact with a specific allergen to which the patient develops specific sensitivity. This type of cutaneous reaction is associated with inflammation manifesting with erythema, edema, and vesicles...

Recruitment of neutrophils and eosinophils into the skin is a hallmark of pemphigoid diseases. The molecular cues regulating granulocyte recruitment into the skin as well as the individual contribution of neutrophils and eosinophils to pemphigoid diseases are, however, poorly understood. The lipid mediator leukotriene B4 (LTB4) is a potent granulocyte chemoattractant and abundant in the skin blister fluid of bullous pemphigoid (BP) patients, but its pathogenic significance is unknown. Using mouse models of (BP)-like epidermolysis bullosa acquisita (EBA) and of BP, we show that LTB4 and its receptor BLT1 act as critical drivers of neutrophil entry into the skin upon antibody deposition at the dermal-epidermal junction...

Several dermatoses are typified by the formation of spaces (blisters; bullae) within or beneath the epidermis. These may be acellular or filled with particular species of inflammatory cells. Etiological categories include infectious, immune-mediated, genetic, drug-related, and idiopathic lesions. Examples of such disorders include impetigo, Herpes virus infections, pemphigus, bullous pemphigoid and pemphigoid gestationis, epidermolysis bullosa acquisita, IgA-related dermatoses, inherited epidermolysis bullosa variants, Hailey-Hailey disease, and porphyria cutanea tarda...

This review is in two sections. The first section summarises 35 conditions, both common and infrequent, causing cicatrising conjunctivitis. Guidelines for making a diagnosis are given together with the use of diagnostic tests, including direct and indirect immunofluorescence, and their interpretation. The second section evaluates our knowledge of ocular mucous membrane pemphigoid, which is the commonest cause of cicatrizing conjunctivitis in most developed countries. The clinical characteristics, demographics, and clinical signs of the disease are described...

REVIEW

Bullous pemphigoid (BP) is the most common autoimmune blistering disease and is linked to IgG recognition of 2 hemidesmosomal antigens, that is, BP230 (BP antigen 1) and BP180 (BP antigen 2, collagen XVII). The association of BP with other systemic diseases, particularly neurocognitive diseases, provides a potential clue in the underlying pathogenesis of BP. The role of HLA-DQB1*03:01 binding to the immunogenic portion of BP180 provides a potential mechanism by which exposure to neuronal collagen BP180 may lead to cutaneous disease...
