BACKGROUND: Linear IgA bullous dermatosis (LABD) is an autoimmune blistering skin disorder characterized by linear IgA deposits along the dermoepidermal junction. Usually idiopathic, LABD can be drug-induced. OBJECTIVE: To report the atypical characteristics of a case of trimethoprim-sulfamethoxazole-induced LABD presenting as toxic epidermal necrolysis (TEN). METHODS: A 63-year-old woman treated with trimethoprim-sulfamethoxazole for Pneumocystis jirovecii infection developed a generalized maculopapular rash with herpetiform lesions, rosette-like lesions, and tense bullae with Nikolsky sign...

Linear IgA bullous dermatosis is a rare autoimmune vesiculobullous disease characterized by linear deposition of IgA along the basement membrane zone. It is classically idiopathic, but may also arise secondary to drug exposure. A heterogeneous spectrum of clinical features has been described, including a rare, morbid variant mimicking toxic epidermal necrolysis. Herein, we present a case of vancomycin-induced linear IgA bullous dermatosis that manifested clinically as toxic epidermal necrolysis and resolved with dapsone therapy...

Bullous pemphigoid (BP) is an immune mediated bullous disease that is manifested by urticarial plaques with superimposed subepidermal blisters and significant pruritus. It is generally found in the elderly, but is rare in the pediatric population. A 5-month-old girl previously diagnosed with hand-foot-mouth disease was examined in our dermatology department owing to vesicles and bullae, initially located to the hands and feet, which progressed with new lesions. Tense vesicles and bullae distributed in an annular string of pearls pattern on the abdomen and facial and cervical regions were noted...

BACKGROUND: Linear IgA bullous dermatosis (LABD) is an autoimmune subepidermal blistering disease usually with a neutrophil rich inflammatory infiltrate, and characterized by linear IgA deposition at the basement membrane zone (BMZ), and neutrophil predominant dermal inflammation. We report a case of LABD with numerous eosinophils and flame figure formation, a unique histopathologic finding not previously reported. A 69-year-old woman presented with a rapidly progressive, intensely pruritic rash over forearms, breasts, axillae, hips, and thighs...

Linear IgA bullous dermatosis (LABD) is a rare autoimmune bullous disorder characterized by linear deposits of IgA at the basement membrane zone(BMZ) and/or by circulating IgA anti-BMZ antibodies. Comparing with other immuno-bullous diseases, LABD represents a heterogeneous disease entitywith diversity of pathogenic IgA autoantibodies to different hemidesmosomal antigens and an association with malignancies and occasional drug use. We herein present an 82-year-old Japanese man with LABD, whose indirect immunofluorescence using 1M NaCl-split skin showed positive staining for IgA at the dermal side alone...

Vancomycin (VCM) is known to induce linear IgA bullous dermatosis (LAD). However, in contrast to conventional LAD, in which circulating IgA autoantibodies against basement membrane proteins are commonly detected, patient sera from VCM-induced LAD (vLAD) yields negative results in indirect immunofluorescence microscopy, and the targeted autoantigen remains undetermined. By utilizing sera from a typical case of vLAD, we identified that co-incubation of sera with VCM resulted in linear IgA deposition at the basement membrane zone (BMZ) by indirect immunofluorescence...

Coeliac disease (CD) is an autoimmune disease, characterised by a permanent sensitivity to gluten. It is being progressively recognised as a multisystemic disease, with multiple extraintestinal manifestations. Skin conditions (eg, dermatitis herpetiformis) are an example of its manifestations; however, its underlying mechanisms are still not well understood. This article presents three cases of uncommon skin conditions in patients with a history of CD. Two of them concern linear IgA bullous dermatosis and erythema nodosum, which have been described in the literature as having potential associations with CD, though only a few cases were reported...

Linear IgA bullous dermatosis is characterized by IgA autoantibodies reactive with LAD-1 and LABD97, truncated forms of BP180 (type XVII collagen), but not with full-length BP180. Toyonaga et al. determined that cleavage within both the C-terminal region and NC16A domain plays a role in exposure of neoepitopes on the 15th collagenous domain of BP180.

BACKGROUND: Extracorporeal treatments such as hemodialysis and plasma exchange are lifesaving measures in the treatment of drug poisoning. This treatment method generally is not used for severe cutaneous and systemic drug reactions. METHODS: Here, we describe three cases wherein hemodialysis therapy was instrumental in reversing the adverse drug reaction. RESULTS: In the cases of severe cutaneous drug reactions reviewed, patients presented with linear immunoglobulin A bullous dermatosis, acute generalized exanthematous pustulosis, and toxic epidermal necrolysis...

Subepidermal autoimmune bullous diseases of the skin and mucosae comprise a large group of chronic diseases, including bullous pemphigoid, pemphigoid gestationis, mucous membrane pemphigoid, linear IgA bullous dermatosis, epidermolysis bullosa acquisita, and anti-p200 pemphigoid. These diseases are characterized by an antibody response toward structural components of the basement membrane zone, resulting in subepidermal blistering. The epidemiological features of these diseases vary substantially in different regions of the world...

<p>Extravasation of medications can manifest as tenderness, pain, tissue necrosis, and thrombophlebitis and lead to infection and severe long-term complications. Risk factors for leakage of medications include mechanical and pharmacologic mechanisms such as cannulation technique, vasoconstriction, and cytotoxicity. Well-known vesicants like anthracyclines, vinca alkaloids, and vasopressors are usually administered with proper caution. Often overlooked are many antimicrobial agents, which typically act via differences in osmolality and pH...

Helicobacter pylori is a gram-negative, flagellate, microaerophilic bacterium identified for the first time about 30 years ago, as a pathogenic factor of gastritis and peptic ulcer. Soon after, it was linked to several gastrointestinal and extra-gastrointestinal diseases (hematological, cardiovascular, neurological, pulmonary and ocular diseases, obesity, diabetes mellitus, growth retardation and extragastric MALT lymphoma). Association and possible cause-effect correlation with H. pylori infection were suggested in diseases of dermatological interest such as chronic urticaria, rosacea, Henoch-Schoenleins purpura, idiopathic thrombocytopenic purpura, cutaneous and oral lichen planus, atopic dermatitis, recurrent aphthous stomatitis, systemic sclerosis, psoriasis, Sjögrens syndrome, Behçet's disease, pruritus, alopecia areata, primary cutaneous marginal zone B-cell lymphomas, vitiligo, chronic prurigo, multiformis, prurigo nodularis, leukocytoclastic vasculitis, prurigo pigmentosa, eczema nummulare, primary cutaneous MALT-type lymphoma, sublamina densa-type linear IgA bullous dermatosis, Sweet's syndrome, cutaneous T-cell pseudolymphoma and pemphigus vulgaris...

Linear IgA bullous dermatosis (LABD) is an autoimmune disease characterized by blisters on the skin and mucous membranes. Polycyclic, grouped bullae on cutaneous skin are the most characteristic clinical feature of LABD. Lesions are often indistinguishable from bullous pemphigoid or may resemble dermatitis herpetiformis. Oral lesions may be seen in 5% to 70% of patients with LABD, and in some cases, the oral mucosa may be the only area of involvement. Herein, we report a patient with LABD involving only the oral mucosa clinically...

Linear immunoglobulin (Ig)A/G bullous dermatosis (LAGBD) is an autoimmune bullous disease characterized by formation of subepidermal blisters and linear deposition of IgA and IgG antibodies along the basement membrane zone (BMZ). The association between linear IgA bullous dermatosis and ulcerative colitis (UC) is well recognized, but reports of UC-associated LAGBD are lacking. We have reported a 24-year-old man suffering from LAGBD associated with UC, which occurred before exacerbations of skin rash. A skin biopsy indicated a subepidermal blister with an infiltration of primarily neutrophils and eosinophils in the dermis...

Cicatricial Pemphigoid is a subepithelial bullous dermatosis which essentially involves the mucous membranes with cicatricial evolution We report the case of a 66-year old patient hospitalized with erosive gingivitis associated with dysphagia, dyspnea and blurred vision. Dermatologic examination showed erosive lesions involving the palate and the pharynx. Ophthalmologic examination showed symblepharons, ectropion and bilateral cataract. Gingival biopsy revealed a necrotic detachment of the buccal epithelium...
