Abstract
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. His story was told through caregivers. Although mostly compliant, the patient was reserved and indifferent, and had little to add even with direct questions.

Abstract
Autoantibodies binding to the extracellular domains of desmoglein (Dsg) 3 and 1 are critical in the pathogenesis of pemphigus by mechanisms leading to impaired function of desmosomes and blister formation in the epidermis and mucous membranes. Desmosomes are highly organized protein complexes which provide strong intercellular adhesion. Desmosomal cadherins such as Dsgs, proteins of the cadherin superfamily which interact via their extracellular domains in Ca2+-dependent manner, are the transmembrane adhesion molecules clustered within desmosomes. Investigations on pemphigus cover a wide range of experimental approaches including biophysical methods. Especially atomic force microscopy (AFM) has recently been applied increasingly because it allows the analysis of native materials such as cultured cells and tissues under near-physiological conditions. AFM provides information about the mechanical properties of the sample together with detailed interaction analyses of adhesion molecules. With AFM, it was recently demonstrated that autoantibodies directly inhibit Dsg interactions on the surface of living keratinocytes, a phenomenon which has long been considered the main mechanism causing loss of cell cohesion in pemphigus. In addition, AFM allows to study how signaling pathways altered in pemphigus control binding properties of Dsgs. More general, AFM and other biophysical studies recently revealed the importance of keratin filaments for regulation of Dsg binding and keratinocyte mechanical properties. In this mini-review, we reevaluate AFM studies in pemphigus and keratinocyte research, recapitulate what is known about the interaction mechanisms of desmosomal cadherins and discuss the advantages and limitations of AFM in these regards.

Abstract
A 58-year-old man presented to our department with multiple chronic vegetant plaques on the face and scalp that had been present for 4 months. The plaques were well-defined hypertrophic areas, measuring between 3 cm × 3 cm and 3 cm × 4 cm, that were located mainly on the face symmetrically and on the forehead (Figure 1). The patient did not report itching or pain. There were also dry, crusty, well-defined plaques on the scalp. No other lesions were present on the skin or mucous membranes.

Abstract
Senear-Usher Syndrome, or pemphigus erythematosus, is an autoimmune skin blistering disorder with an overlapping clinical presentation of pemphigus foliaceus and lupus erythematosus. Lesions typically involve the scalp, face, and upper chest or back. This case study focuses on a patient who presentedwith progressive scalp ulcers, hyperpigmentation, and eroded plaques with overlying hemorrhagic crust. Pemphigus erythematosus was diagnosedwith direct immunofluorescence, demonstrating immunoglobulin G and complement deposition both intercellularly and at the dermoepidermal junction. The patient is continuing treatment with systemicsteroids and steroid-sparing immunosuppressants.

Abstract
Paraneoplastic Pemphigus (PNP) is a rare and often fatal autoimmune mucocutaneous blistering disease associated with an underlying malignancy. It is thought to be caused by antibodies to tumor antigenscross-reacting with epithelial antigens, specifically desmosomal and hemidesmosomal antigens. There are at least five clinical morphologic variants of PNP, with the earliest and most consistent finding beingsevere stomatitis. Diagnosis of PNP requires direct immunofluorescence of perilesional skin and indirect immunofluorescence. Treatment of PNP is difficult and largely limited to glucocorticoids, steroid-sparing immunomodulators, rituximab and intravenous immunoglobulin (IVIG). Despite therapies, prognosis is poor. We report a case of paraneoplastic pemphigus in a 34-year old male with severe stomatitis and lichenplanus-like cutaneous lesions.

Abstract
Pemphigus vulgaris, mucosal pemphigoid (mucous membrane pemphigoid), lichen planus, discoid lupus erythematosus and erythema multiforme are a group of immune-mediated mucocutaneous disorders characterised clinically by the formation of blisters, erosions or ulcers. The oral mucosa is often affected, and sometimes the disease is limited to the mouth. The target antigens, autoreactive immune responses, microscopic features, treatment and prognosis vary from one disease to the other. Treatment aims to eliminate exogenous risk factors, suppress the pathogenic immuno-inflammatory reactions, promote healing and prevent infection. The aim of this article is to provide the general dental practitioner with a succinct overview of the diagnostic, clinical, aetiopathogenic features and characteristics of, as well as treatment guidelines for oral pemphigus vulgaris and oral mucosal pemphigoid. Early diagnosis and treatment could prevent severe consequences of the disease in their full-blown forms.

Abstract
RATIONALE Paraneoplastic pemphigus (PNP) is an autoimmune syndrome associated with neoplasms. The treatment approach principally includes suppressing the immunity, but its therapeutic effect is not satisfying. PATIENT CONCERNS We report a case of paraneoplastic pemphigus linked to chronic lymphocytic leukemia in a 63-year-old man. DIAGNOSES At first, the patient was diagnosed with pityriasis rose caused by a viral infection. Biopsies for histology and immunofluorescence showed PNP, was treated with immunosuppressive and antiinfective therapy. INTERVENTIONS Immunosuppressive and antiinfective therapy were performed. OUTCOMES The skin lesions of PNP were alleviated. However, the infections were aggravated and the disease progressed. The patient died of respiratory failure. LESSONS Treatment for PNP should be adapted to disease severity as early as possible. Antiinfection treatment should be timely and effective because infections are the most common complication that can lead to death.

Abstract
Mucocutaneous diseases affect the oral cavity and can present a diagnostic challenge. They can have systemic involvement, necessitating multidisciplinary management. Frequently, patients will see their general dentists initially for evaluation. A better understanding of mucocutaneous diseases can prevent delay in appropriate diagnosis and treatment. Oral lichen planus, mucous membrane pemphigoid and pemphigus vulgaris are three mucocutaneous diseases that affect the oral mucosa. This review describes the clinical features, epidemiology, etiology, pathogenesis and management for each condition.

Abstract
Few cases have been published relating systemic lupus erythematosus (SLE) and pemphigus vulgaris (PV). We describe a patient with this association. A 35-year old woman who started to develop persistent pain and morning stiffness of proximal inter and metacarpo-phalangeal joints. During the following year, the patient recalled the onset of blisters on both legs, face, arms and thorax, as well as erosions appearing on oral mucous membranes. We observed generalized multiple erosions on her trunk and legs, flaccid bullae located on her right thigh and multiple erosions on oral mucous membranes. A skin biopsy reported PV. Direct immunofluorescence on the perilesional skin specimen, showed beehive intercellular IgG deposits in the epidermis (+++), suggesting PV; granular discontinuous IgM and C3 deposits in the dermal-epidermal union (+++), suggesting SLE. Direct immunofluorescence of the healthy unexposed skin specimen, reported granular discontinuous IgG deposits in the dermal-epidermal union and beehive intercellular IgG deposits in the lower levels of the epidermis (+++); granular continuous IgM deposits in the dermal-epidermal union (+++). The results of rheumatic studies were obtained as follows: ANA: 3 +, Anti-DNA, Anti-Sm, Anti-Ro and Anti-La: 4 +. The definite diagnosis was PVand SLE. Treatment with 50 mg of prednisone daily with good evolution.

Abstract
Pemphigus vegetans is a rare autoimmune blistering acantholytic dermatosis of humans that combines unusually hyperplastic and verrucous pustular skin lesions and mucosal erosions. We report herein the clinical, histopathologic, and immunologic findings in a dog whose lesions resembled, but were not identical to, those of human pemphigus vegetans. A 4-year-old male Greater Swiss Mountain Dog presented with multifocal cutaneous verrucous and crusted papules and pustules, as well as skin and mucosal erosions and ulcers. Microscopic lesions consisted of exophytic papillated epidermal hyperplasia, superficial and deep intraepidermal acantholytic neutrophilic and eosinophilic pustules, and suprabasal epidermal clefts leaving rounded basal keratinocytes at the bottom of the vesicles. Direct and indirect immunofluorescence revealed antikeratinocyte IgG autoantibodies. Immunoprecipitation immunoblotting and immunoabsorption experiments with recombinant canine desmogleins confirmed that autoantibodies recognized desmoglein-1. In this dog, clinical and histopathologic features resembled those of human pemphigus vegetans, while circulating autoantibodies against canine desmoglein-1 were solely identified. This antigen target is different from that of the human disease in which antidesmoglein-3 autoantibodies are detected most commonly.

Abstract
Paraneoplastic pemphigus (PNP) is an autoimmune blistering skin disease of humans that consists of characteristic skin lesions associated with concurrent neoplasia. in this study we provide histologic and serologic evidence to support a diagnosis of PNP in a dog with splenic sarcoma. Skin lesions consisted of widespread erosions involving haired skin, mucocutaneous junctions, and oral mucosa. Microscopic examination of skin and mucosae revealed lesions consistent with both pemphigus vulgaris and erythema multiforme. Immunoprecipitation confirmed that circulating IgG autoantibodies from this patient recognized five distinct antigens, presumed to represent epidermal plakins. Clinical, histopathologic, and immunologic findings in this patient were similar to those observed in human patients with PNP. The splenic neoplasia in this dog was diagnosed as a phenotypically variable spindle cell sarcoma. To date, only one other dog has been reported with PNP. This is the second reported case of canine PNP and the first patient in whom skin lesions were identified in association with splenic neoplasia.

Abstract
BACKGROUND Pemphigus is part of a group of blistering diseases that affect the skin and mucous membranes. Based on its autoimmune origin, autoantibodies develop in pemphigus that are directed toward cell surface components of keratinocytes. However, some data cannot be explained, such as the lack of a relationship between autoantibody levels and the severity of clinical manifestations, treatment resistance, the presence of inflammatory infiltrates and the potential occurrence of apoptosis as determinants of vesicle formation. OBJECTIVE To examine the presence of apoptosis in pemphigus vulgaris by TUNEL technique. METHODS In this cross-sectional study, we selected 15 paraffin-embedded tissues from subjects who were diagnosed with pemphigus vulgaris by hematoxylin and eosin staining. The samples were subjected to TUNEL assay and examined under an Olympus BX61 fluorescence microscope. Positivity was categorized dichotomously, and the statistical analysis was performed using the X2 test. RESULTS Positivity was observed in basal layer cells in 14 (93.3%) cases. In 13 (86.7%) of the positive cases, we noted espinosum and granular layers that formed the blister roof, and in 12 cases (80%), positive acantholytic cells were observed. CONCLUSIONS TUNEL positivity was observed in pemphigus vulgaris, implicating apoptosis in the pathophysiology of this condition, which can help guide the development of apoptotic blockers as therapeutics.

Abstract
Pemphigus foliaceus (PF) is a sporadic autoimmune blistering disease of unknown etiology. The production of immunoglobulin G4 antibodies against desmoglein-1 is responsible for the clinical manifestation of PF. We present a case of a woman with a recent diagnosis of myasthenia gravis (MG), who was also recently treated with radiation therapy for breast cancer. The clinical exam, supported by biopsy and direct immunofluorescence, were consistent with PF. We present this case to increase the awareness of the potential exacerbation or induction of PF with radiation, and of the association of PF and myasthenia gravis. Only five prior cases of radiation-exacerbated or radiation-induced PF have been reported in the literature to date. Furthermore, the co-existence of the autoimmune entities of myasthenia gravis and PF has been reported in the literature in only 9 cases and was also noted in this patient.
