Pemphigus vulgaris (PV) is a chronic autoimmune mucocutaneous disease. In most cases, the initial manifestation occurs in the mouth as multiple ulcerations preceded by blisters that rupture and later spread to other mucous membranes and the skin. Esophageal impairment is rare. We report a case of PV with esophageal involvement in a 53-year-old woman who sought medical care, complaining of diffuse painful lesions in the oral cavity for approximately 1 month, with no improvement with nystatin. Upper digestive endoscopy (UDE) was performed with findings of vesiculobullous lesions in the proximal and middle esophagus, which were biopsied and for which histopathology confirmed PV in the esophageal mucosa...

Pemphigus is an autoimmune disease characterized by intraepithelial bullae and erosions in the skin and mucosa. We aimed to evaluate the clinical and demographic characteristics of pemphigus vulgaris (PV) patients who presented to our Department. Patients who presented to our Department between May 2013 and May 2014, were examined dermatologically and diagnosed with PV based on clinical, histological and direct immunofluorescent findings. Name, family name, and gender of the patients, their complaint at presentation, onset time and location of the lesions, the number of lesions, systemic treatments received by patients and patients' medication histories were recorded...

According to the "desmoglein compensation theory," anti-Dsg1 and anti-Dsg3 profiles are crucial for the clinical outcome of pemphigus vulgaris. However, recent studies have highlighted several cases with an incompatibility between the antibody profile and clinical manifestation. Data of 37 patients who had been diagnosed pemphigus vulgaris in our Department between January 2014-June 2016 were retrieved from our clinical database. Patients with ABSIS skin involvement scores, oral mucosa extent and severity scores, anti-Dsg1 and Dsg3 antibody profile were included in this retrospective study...

Anti-desmoglein (anti-Dsg) ELISA and indirect immunofluorescence (IIF) are used for the diagnosis of pemphigus vulgaris (PV). The value of salivary ELISA, serum ELISA, and IIF in the diagnosis of PV, and the correlation of salivary anti-Dsg1 and anti-Dsg3 ELISA with serum ELISA, serum and salivary IIF titers, and disease severity in patients with PV were evaluated. Fifty newly diagnosed patients with PV were enrolled in the study. Demographic data and disease-severity scores were recorded for each patient. Anti-Dsg1 and anti-Dsg3 ELISA and IIF were performed on both serum and salivary samples...

Oral signs are frequently the first manifestation of autoimmune diseases. For this reason, dentists play an important role in the detection of emerging autoimmune pathologies. Indeed, an early diagnosis can play a decisive role in improving the quality of treatment strategies as well as quality of life. This can be obtained thanks to specific knowledge of oral manifestations of autoimmune diseases. This review is aimed at describing oral presentations, diagnosis, and treatment strategies for systemic lupus erythematosus, Sjögren syndrome, pemphigus vulgaris, mucous membrane pemphigoid, and Behcet disease...

The single pass, transmembrane proteins of the cadherin family have been appreciated as important proteins that regulate intercellular adhesion. In addition to this critical function, cadherins contribute to important signalling events that control cellular homeostasis. Many examples exist of classical, desmosomal, and atypical cadherins participating in the regulation of signalling events that control homeostatic functions in cells. Much of the work on cadherin mediated signalling focuses on classical cadherins or on specific disease states such as pemphigus vulgaris...

The skin is the largest organ of the body, at the boundary with the outside environment. Primarily, it provides a physical and chemical barrier against external insults, but it can act also as immune organ because it contains a whole host of immune-competent cells of both the innate and the adaptive immune systems, which cooperate in eliminating invading pathogens following tissue injury. On the other hand, improper skin immune responses lead to autoimmune skin diseases (AISD), such as pemphigus, bullous pemphigoid, vitiligo, and alopecia...

Checkpoint inhibitors (CPIs) restore the function of effector immunocytes to target and destroy cancer cells. Immune-related adverse events (irAEs) are a consequence of immune reactivation, with unpredictable inflammatory response, loss of self-tolerance, and development of autoimmunity. Adverse events from CPIs that present as dermatologic toxicities have diverse clinical and histopathologic features. CPI-associated dermatologic toxicities may exhibit histopathologic features of lichenoid dermatitis, bullous pemphigoid, and granulomatous/sarcoid-like reactions...

Cicatricial pemphigoid (CP) is a chronic, autoimmune, subepidermal blistering disease with predominant mucosal involvement. In this article, we report a young patient with mucosal and extensive cutaneous involvement in the form of large erosions mimicking those of pemphigus vulgaris thus leading to diagnostic dilemma. We were unable to find any other previous reports with such extensive cutaneous erosions mimicking those of pemphigus vulgaris. Laminin 5 was the antigen found on knockout substrate testing. Antiepiligrin CP is a distinct subtype of CP with antibodies against laminin 5...

A seven-month-old girl was referred to the emergency department (ED) after a general practitioner suspected Steven-Johnson syndrome. Actually, the diagnosis of bullous pemphigoid (BP) was made based on biopsies; BP is a rare, autoimmune skin disease involving the presence of blisters known as bullae. The child was efficiently treated with topical steroids. This case shows the importance of the ED physician's prior knowledge of BP so that a differential diagnosis with other autoimmune diseases (dermatosis, pemphigus) can be made...

Background: Follicular dendritic cell sarcoma (FDCS) is an extremely rare malignant tumor caused by proliferation of antigen-presenting follicular dendritic cells. The tumor most commonly arises in lymph nodes, with fewer than 30% of cases originating in extranodal sites. Case Presentation: We report the case of a 39-year-old previously healthy male patient who presented with paraneoplastic pemphigus in the setting of a large intraperitoneal mass with no associated lymphadenopathy...

Pemphigus vulgaris (PV) is a potentially lethal autoimmune disease characterized by blister formation of the skin and mucous membranes and is caused by autoantibodies against desmoglein (Dsg) 1 and Dsg3. Dsg1 and Dsg3 are linked to keratin filaments in desmosomes, adhering junctions abundant in tissues exposed to high levels of mechanical stress. The binding of the autoantibodies leads to internalization of Dsg3 and a collapse of the keratin cytoskeleton-yet, the relevance and interdependence of these changes for loss of cell-cell adhesion and blistering is poorly understood...

Pemphigus vulgaris (PV) is a potentially life-threatening mucocutaneous autoimmune blistering disease. Patients develop non-healing erosions and blisters due to cell-cell detachment of keratinocytes (acantholysis), with subsequent suprabasal intraepidermal splitting. Identified almost 30 years ago, desmoglein-3 (Dsg3), a Ca2+ -dependent cell adhesion molecule belonging to the cadherin family, has been considered the "primary" autoantigen in PV. Proteomic studies have identified numerous autoantibodies in patients with PV that have known roles in the physiology and cell adhesion of keratinocytes...

Dermatology was consulted in the care of a 58-year-old man with a history of paranoid schizophrenia, neuroleptic malignant syndrome, a positive purified protein derivative test, and a lack of bathing for approximately 4 years who had been admitted to the hospital because of thick, crusted lesions over an increasing portion of his body. Admitted involuntarily, he was disinterested in the history, physical examination, and diagnostic testing. Comorbid schizophrenia presented a unique challenge because he was unable to participate in his care effectively...

There is a little consensus regarding the association of pemphigus with autoimmune thyroid diseases. While this association had been confirmed by some observational studies, others had refuted it. We aimed to study the association between pemphigus and Hashimoto's thyroiditis, Grave's disease, and thyroid cancer using a large-scale real-life computerized database. A cross-sectional study was performed to compare pemphigus patients with age-, sex-, and ethnicity-matched control subjects regarding the prevalence of overt thyroid diseases...
