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...

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...

Bullous pemphigoid is a potentially life-threatening autoantibody-mediated dermatosis characterized by blister formation. Experimental mouse models of bullous pemphigoid feature complement-induced inflammation and tissue damage. Kasprick et al. now provide preclinical data that utilize ex vivo human skin assays and support testing of complement inhibition as a therapeutic strategy in human bullous pemphigoid.

A 71-year-old woman presented with pink to violaceous, flat-topped, polygonal papules on the volar wrists, extensor elbows, and bilateral lower legs of 3 years' duration. She also had erythematous, violaceous, infiltrated plaques with microvesiculation on the bilateral thighs of several months' duration. She reported pruritus, burning, and discomfort. Her medical history included type 2 diabetes mellitus, hypertension, and asthma with no history of skin rashes. Workup revealed lichen planus pemphigoides (LPP), a rare papulosquamous and vesiculobullous dermatosis that shares features of both lichen planus (LP) and bullous pemphigoid (BP)...

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...

BACKGROUND: Heparin-induced haemorrhagic bullous dermatosis (HBD) is a rare but probably underdiagnosed reaction to heparin, with 26 cases reported in the English literature. Currently, there is no consensus regarding the treatment. AIM: To assess our new cases of HBD and review the previously reported cases, in order to draw conclusions about this adverse skin reaction to heparin. METHODS: A PubMed search was performed for articles containing the terms '(heparin-induced AND (blister OR bulla OR bullae)) OR (hemorrhagic bullous dermatosis AND heparin) OR heparin bullous dermatosis'...

Lichen planus pemphigoides (LPP) is a rare autoimmune bullous dermatosis. The clinical presentation of LPP may mimic bullous pemphigoid making the diagnosis difficult. A thorough clinical, histopathological, and immunological evaluation is essential for the diagnosis of LPP. The etiology is largely idiopathic; however, there are several case reports of drug-induced LPP. We report an 81-year-old Thai woman with underlying hypertension and type 2 diabetes mellitus who presented with a 4-week history of multiple tense bullae initially on the hands and feet that subsequently expanded to the trunk and face...

REVIEW

Bullous pemphigoid (BP) is by far the most common autoimmune blistering dermatosis that mainly occurs in the elderly. The BP180 is a transmembrane glycoprotein, which is highly immunodominant in BP. The structure and location of BP180 indicate that it is a significant autoantigen and plays a key role in blister formation. Autoantibodies from BP patients react with BP180, which leads to its degradation and this has been regarded as the central event in BP pathogenesis. The consequent blister formation involves the activation of complement-dependent or -independent signals, as well as inflammatory pathways induced by BP180/anti-BP180 autoantibody interaction...

Sweet syndrome (SS) or acute febrile neutrophilic dermatosis presents with the sudden onset of fever, leukocytosis and tender, erythematous, edematous, well-demarcated papules and plaques that histopathologically demonstrate a dense neutrophilic infiltrate. A total of 20% of patients with SS have malignancy-associated disease that can present with bullous or atypical skin lesions that mimic pyoderma gangrenosum, another neutrophilic dermatosis. Both entities exist on a spectrum, and in the context of underlying malignancy, these neutrophilic diseases become less clinically distinct...

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...
