A 67-year-old man with diabetes, weight loss and anaemia initially presented with a widespread scaling erythematous rash; a skin biopsy demonstrated marked suprabasal acantholysis. A subsequent biopsy showed localized upper epidermal necrolysis and the diagnosis of glucagonoma syndrome was later
We report a unique case of a Japanese woman with herpetiform pemphigus (HP) who had IgG autoantibodies reactive with nondesmosomal sites of keratinocytes and presented characteristic transmission electron microscopic (TEM) findings of various-sized vacuoles in keratinocytes without acantholysis. The
Herpetiform vesicles and erythema with erosion developed on the trunk of a 48-year-old Japanese man. Acantholysis was observed in the spinous layer of the lesional epidermis and direct immunofluorescence revealed cell surface deposition of immunoglobulin IgG and C3. Indirect immunofluorescence could
This article describes a case of unusual annular erythema-like dermatosis, with histological features of pemphigus foliaceus (subcorneal acantholysis) and IgG antibodies in circulation and bound in vivo to the keratinocyte surface. The reactivity of the antibodies, restricted to human squamous
In a previous report, we described autoantibodies against the desmosomal plaque proteins desmoplakin I and II (dp I and II) in patients with erythema multiforme (EM) major. In the present study we investigated ten EM major and eight EM minor patients for circulating autoantibodies and performed
The demonstration of circulating autoantibodies directed against the constitutive desmosomal plaque proteins desmoplakin (dp) I and II in mucocutaneous lesions in a subset of patients with erythema multiforme major, suggests that humoral immune mechanisms may play a role in the pathogenesis of this
BACKGROUND
Intense pulsed light (IPL) systems emit non-coherent, polychromatic light and are increasingly used for various dermatologic indications. Although generally regarded as safe therapy, IPL is not without risk.
OBJECTIVE
We report a 21-year-old woman who experienced a severe blistering
Cell/cell and cell/matrix adhesion proteins are responsible for maintaining the integrity of the mucosal lining of the oral cavity. Disease processes that destroy keratinocytes or adversely affect their adhesion to one another or to the subjacent basement membrane will result in erosions,
The research goal was to establish the neonatal mouse model by specific rabbit anti EC1-2 or EC3-4 antiserum for the purpose of studying pemphigus vulgaris (PV) pathogenesis. RNA was extracted from human keratinocytes. The cDNAs was synthesized by reverse transcription. Amplified EC1-2 or EC3-4
Pemphigus foliaceus (PF) is an autoimmune skin disease in which loss of adhesion between keratinocytes (i.e., acantholysis) in the granular cell layers appears to be mediated by the binding of autoantibodies against desmoglein (Dsg) 1. Although it has been suggested that the activity of the disease
IgA pemphigus of the subcorneal pustular dermatosis type is a rare autoimmune blistering disease in the pemphigus spectrum. Patients are clinically characterized by extensive erythemas that primarily affect intertriginous areas. The erythematous macules are covered with numerous vesicles and
We report an unusual variant of pemphigus in a 44-year-old man. He presented with scaly and crusted erosions associated with pruritic vesicles and erythema mainly on the chest, abdomen, back and face. Histology showed acantholysis with neutrophilic spongiosis in the granular layer and subcorneal
Herpetiform pemphigus (HP) is a rare variant of pemphigus characterized by a unique clinical phenotype of erythematous or urticarial plaques and vesicles that present in a herpetiform arrangement. Most HP cases have circulating anti-desmoglein 1 (Dsg1) IgG autoantibodies, but some HP cases have
A patient with extensive histologically proven Hailey-Hailey disease is described whose initial clinical presentation was suggestive of erythema multiforme or toxic epidermal necrolysis. This potentially misleading morphology of acute proven Hailey-Hailey disease has not been described previously
