Abstract
Only limited cases have been reported about the clear cell variant of squamous cell carcinoma occurring in the oral cavity. The present study regards the case showing the histopathological features of both the clear cell and acantholytic variants of oral squamous cell carcinoma. A review of the literature has been done to understand the pathogenesis of those changes. Also, a hypothesis has been given that the clear cell changes could be the consequences of the cascades of the acantholytic process and not a separate entity. Therefore, more research is required to confirm this hypothesis and understand the prognosis of the lesion.

Abstract
INTRODUCTION AND IMPORTANCE Pemphigus Vulgaris (PV) is a low incidence autoimmune mucocutaneous bullous disease, in which pathogenic antibodies are directed against the keratinocyte cell surface. Although anal involvement is unusual, correlations between its appearance and disease severity have been recently reported. CASE PRESENTATION A 42-year-old male presented with an anal fissure and a year of recurrent oral and pharyngeal aphtha. A chemical sphincterotomy with botulinum toxin plus fissurectomy was performed. 3 years later an upper eyelid injury raised suspicion of pemphigus vulgaris (PV), tested negative for specific antibodies. A couple years later, an anal fissure, and suspected Crohn's disease, led to a second intervention. Surgical analysis unveiled characteristics indicative of a vegetating variant of PV. CLINICAL DISCUSSION Anal involvement in PV varies in prevalence, with studies reporting rates between 2 % and 27.98 %. This manifestation often accompanies late disease stages and may indicate severity, notably in association with oral lesions. Patients might not readily discuss anal symptoms, leading to potential underreporting. Anal PV is linked to other lesions (ocular, nasal, genital) and the severity of oral PV. Even when other sites are in remission, anal recurrence can occur. Early recognition and follow-up are crucial, highlighting the need for routine anal examination and confirmatory diagnostics. CONCLUSION PV lesions can present on the skin or mucosa, although oral lesions are the most common site of initial presentation. Anal PV is a diagnostic challenge, and this case illustrates the importance of a careful evaluation.

Abstract
BACKGROUND Glucocorticoids are the first-line treatment for Pemphigus vulgaris (PV), but its serious side effects can be life-threatening for PV patients. Tacrolimus (FK506) has been reported to have an adjuvant treatment effect against PV. However, the mechanism underlying the inhibitory effect of FK506 on PV-IgG-induced acantholysis is unclear. OBJECTIVE The objective of this study was to explore the effect of FK506 on desmoglein (Dsg) expression and cell adhesion in an immortalized human keratinocyte cell line (HaCaT cells) stimulated with PV sera. METHODS A cell culture model of PV was established by stimulating HaCaT cells with 5% PV sera with or without FK506 and clobetasol propionate (CP) treatment. The effects of PV sera on intercellular junctions and protein levels of p38 mitogen-activated protein kinase (p38MAPK), heat shock protein 27 (HSP27), and Dsg were assayed using western blot analysis, immunofluorescence staining, and a keratinocyte dissociation assay. RESULTS PV sera-induced downregulation of Dsg3 was observed in HaCaT cells and was blocked by FK506 and/or CP. Immunofluorescence staining revealed that linear deposits of Dsg3 on the surface of HaCaT cells in the PV sera group disappeared and were replaced by granular and agglomerated fluorescent particles on the cell surface; however, this effect was reversed by FK506 and/or CP treatment. Furthermore, cell dissociation assays showed that FK506 alone or in combination with CP increased cell adhesion in HaCaT cells and ameliorated loss of cell adhesion induced by PV sera. Additionally, FK506 noticeably decreased the PV serum-induced phosphorylation of HSP 27, but had no effect on p38MAPK phosphorylation. CONCLUSION FK506 reverses PV-IgG induced-Dsg depletion and desmosomal dissociation in HaCaT cells, and this effect may be obtained by inhibiting HSP27 phosphorylation.

Abstract
Darier disease is an autosomal dominant disorder with hyperkeratotic papules affecting primarily seborrheic areas of the upper chest, back, forehead, scalp, nasolabial folds, ears, and, less frequently, the oral mucosa. A typical eruption consists of keratotic and crusted skin-colored papules and plaques. Pruritus occurs in 80% of patients, and pain is rare. Lesions can be triggered by exposure to ultraviolet light, heat, or stress. Secondary infections of the lesions are a common complication. A definitive diagnosis is obtained by a biopsy showing histological features such as acantholysis, suprabasal clefts, and "corps rond and grains". Here we present a 37-year-old woman admitted to the gynecology department with pruritic lesions she had noticed on her vulva and perineum for three months. A vulvar biopsy led to the diagnosis of Darier disease. She was referred to the dermatology department and treated with oral acitretin since systemic retinoids are offered as the first-line treatment of the disease.

Abstract
OBJECTIVE Pemphigus vulgaris (PV) is a chronic inflammatory autoimmune blistering disease. Aberrant SOCS3/STAT pathway activation is associated with many autoimmune diseases. This study explored the relationship between activation of the SOCS3/STAT pathway and abnormally increased proportions of Th1 and Th17 cells in the peripheral blood of PV patients as well as the effect of CD4+ T cells with abnormal SOCS3/STAT pathway activation on acantholysis. METHODS In PV patients, the proportions of Th1 and Th17 cells in peripheral blood, the levels of IFN-γ and IL-17 in serum and the mRNA levels of SOCS3 and STAT1/3 in CD4+ T cells were detected. Then, SOCS3-knockdown primary CD4+ T cells were prepared, and cocultured with HaCaT cells. Finally, after SOCS3 knockdown and coculture, CD4+ T cells were collected, and the proportions of Th1 and Th17 cells, the protein levels of STAT1/3 and p-STAT1/3, and the levels of IFN-γ and IL-17 were measured. After 2 days of coculture, HaCaT cells were collected, inflammatory factors mRNA expression and acantholysis were assessed. RESULTS In PV patients, the proportions of Th1 (P = 0.016) and Th17 (P = 0.045) cells and the levels of IFN-γ (P = 0.010) were significantly increased. SOCS3 mRNA in CD4+ T cells was significantly decreased (P = 0.008), whereas STAT1 (P = 0.043) and STAT3 (P = 0.004) mRNA were significantly increased. After SOCS3 knockdown, the proportions of Th1 (P < 0.001) and Th17 (P = 0.006) cells, the levels of IFN-γ (P < 0.001) and IL-17 (P = 0.001), and the protein levels of p-STAT1 (P = 0.001) and p-STAT3 (P = 0.003) were significantly increased in the CD4+ T-shSOCS3-1 group. In the coculture system, the proportions of Th1 (P < 0.001) and Th17 (P < 0.001) cells, the levels of IFN-γ (P < 0.001) and IL-17 (P < 0.001), and the number of cell fragments (P < 0.001) were significantly increased in the CD4+ T-shSOCS3-1+HaCaT-PV-IgG group, whereas the protein level of desmoglein3 (Dsg3) was significantly decreased. In addition, PV-IgG significantly increased IFN-γ and IL-6 mRNA in HaCaT cells. CONCLUSION Low SOCS3 expression in CD4+ T cells from PV patients leads to overactivation of STAT, which causes CD4+ T cells to overdifferentiate into Th1 and Th17 cells. Additionally, PV-IgG-induced local inflammation in skin lesions, which is mediated by IFN-γ and IL-6, can aggravate this phenomenon. Furthermore, low SOCS3 expression in CD4+ T cells further exacerbates PV-IgG-induced acantholysis. Therefore, upregulating the expression of SOCS3 in CD4+ T cells of PV patients and maintaining the balance of the IFN-γ/STAT1/SOCS3 and IL-6/STAT3/SOCS3 pathways can alleviate acantholysis in patients with PV.

Abstract
Autoimmune bullous dermatoses are characterized by the presence of tissue-bound and often circulating pathogenic autoantibodies targeting structural components of the skin and/or mucous membranes. The diagnostic workup for this heterogeneous group of disorders consists of a multi-step process, of which the light microscopic examination is a crucial component. This review is organized following a classification scheme that is based on two main histopathologic features, namely level of intraepithelial split and composition of the inflammatory infiltrate. Overall, we aim to place emphasis on the histopathologic clues that can assist pathologists in differential diagnosis and review the updates in the literature.

Abstract
Pemphigus Vulgaris (PV) is a severe autoimmune disease characterized by supra-basal blisters in the skin and mucous membranes of a wide range of mammals, including humans. It not only affects the skin but also has severe oral manifestations. It has been stated that auto-antibodies are produced, for unknown reasons, which are directed against desmogleins present on the epithelium and thus leads to acantholysis and intraepithelial blistering. But the exact mechanism is still not completely understood. Here we would like to shed light on a new pathologic mechanism i.e., apoptolysis, which emphasizes that apoptotic enzymes contribute to acantholysis development both in terms of molecular events and chronologic sequence. A possible role of apoptolysis has been discussed in purview of PV.

Abstract
Pemphigus is the term used to describe a group of rare mucocutaneous autoimmune bullous diseases characterized by flaccid blisters and erosions of the mucous membranes and/or skin. When the autoantibodies target desmosomes in the deep layers of the epidermis, deep pemphigus variants such as pemphigus vulgaris, pemphigus vegetans and paraneoplastic pemphigus develop. In this article, we will review the signalment, clinical signs, histopathology and treatment outcome of pemphigus vulgaris, pemphigus vegetans and paraneoplastic pemphigus in dogs, cats and horses; where pertinent, we compare the animal diseases to their human homologue. Canine, feline and equine pemphigus vulgaris, pemphigus vegetans and paraneoplastic pemphigus have many features similar to the human counterpart. These chronic and often relapsing autoimmune dermatoses require aggressive immunosuppressive therapy. In animals, the partial-to-complete remission of pemphigus vulgaris and pemphigus vegetans has been achieved with high dose glucocorticoid therapy, with or without adjunct immunosuppressants; the prognosis is grave for paraneoplastic pemphigus.

Abstract
Pemphigus vulgaris (PV) is a potentially lethal mucocutaneous blistering disease characterized by IgG autoantibodies (AuAbs) binding to epidermal keratinocytes and inducing a devastating blistering disease affecting oral and/or esophageal surfaces and, sometimes, also the skin. Anti-keratinocyte AuAbs developed by the desmoglein (Dsg) 1/3 AuAb-negative acute PV patients are pathogenic, as they induced acantholysis and epidermal split in the experimental models of PV in vitro and in vivo. These PV patients have various combinations of AuAbs to keratinocyte muscarinic acetylcholine receptor subtype M3 (M3AR), the secretory pathway Ca2+/Mn2+-ATPase isoform 1 (SPCA1), and desmocollin 3 whose relative concentrations correlate with the disease activity. In this study, we identified new molecular mechanisms of the synergistic cooperation of AuAbs to M3AR and SPCA1 in inducing acantholysis in the anti-Dsg 1/3 AuAb-negative PV patients. Anti-M3AR AuAb was found to play an important role in determining the level of intraepidermal split just above the basal cells, caspase to mediate early pro-apoptotic events triggered by anti-SPCA1 AuAb, and the neonatal Fc receptor (FcRn) to contribute to the pathobiological actions of both anti-M3AR and anti-SPCA1 AuAbs. Altogether, these novel results support our original hypothesis that pemphigus acantholysis is a complex disease process (also known as apoptolysis) initiated by AuAbs directed against different keratinocyte proteins that play important roles in supporting cell viability and regulating vital cell functions.

Abstract
PURPOSE A review of the published literature on the history, pathogenesis, and treatment of pemphigus vulgaris (PV) and its ocular involvement. METHODS Literature searches were conducted in MEDLINE (Ovid), and google scholar for pemphigus vulgaris and ocular PV. Inclusion criteria were given to meta-analysis, case-controlled studies, and documented case reports. The data were examined and independently analyzed by more than two of the authors. RESULTS PV is a humoral autoimmune disease with a preponderance of IgG4 anti-desmoglein 3 antibodies. Upon antibody binding, there is an intracellular signaling mechanism that leads to blister formation. Ocular findings are seen in up to 16% of PV patients with conjunctivitis being the most common clinical presentation. New steroid-sparing agents have helped with the control of this deadly disease, and with better understanding of the pathogenesis of PV, other cytokine blockers currently available are promising steroid-sparing agents. CONCLUSIONS Ocular pemphigus can occasionally present prior to mucocutaneous findings. Recalcitrant conjunctivitis with conjunctival blisters should warrant a workup for systemic PV.

Abstract
Objectives: To evaluate the immunohistochemical expression of Epstein-Barr virus (EBV) in broad spectrum histological subtypes of oral squamous cell carcinoma (OSCC) and to determine the relationship of EBV with clinicopathological parameters of OSCC. Methods: This cross-sectional study included 150 clinically diagnosed OSCC cases from the outpatient of Ziauddin University Hospital from March, 2017 to October, 2018. These were confirmed on histological examination and categorized into conventional squamous cell carcinoma (SCC) and rare variants. Conventional SCC was subcategorized into keratinizing (KSCC), non-keratinizing (NKSCC), and hybrid SCC (HSCC). EBV status was compared among various histological tumor entities and clinicopathological characteristics of OSCC using immunohistochemistry. Chi-square test was used to determine the association of each histological subtype with EBV status with P-value <0.05 considered as statistically significant. Results: Conventional tumor was the most frequent squamous cell carcinoma (n=126; 84%). A significant statistical link of EBV infection was observed with rare histological tumors exhibiting acantholysis (P=0.01), as well as tumors involving buccal mucosa (P=0.03), and habitual smokers (P=0.001). Conclusions: In this study, acantholytic tumor, a rare histological subtype of OSCC, tended to be EBV related. Moreover, OSCC cases bearing EBV infection were more likely smokers favoring buccal mucosa as primary anatomical site for oral cancer.

Abstract
Background Hidradenitis suppurativa is one member of the follicular occlusion triad: acne conglobata, hidradenitis suppurativa, and dissecting cellulitis of the scalp. The presence of acantholysis and desmoglein autoantibodies in hidradenitis suppurativa is rare. Case presentation We report a case of 68-year-old male with a diagnosis of gluteal hidradenitis suppurativa co-presenting pemphigus-like findings including acantholysis and positive desmoglein autoantibodies. Conclusion To our knowledge, comorbidity of gluteal hidradenitis suppurativa and pemphigus-like findings has not been reported before. This case implies a relationship between two different conditions; the follicular occlusion triad and pemphigus, highlighting a potential induction of pemphigus-like lesion by chronic inflammatory process.

Abstract
Carcinoma ex pleomorphic adenoma (CXPA) is a malignant tumor of the salivary gland that arises from pleomorphic adenoma (PA). Squamous cell carcinoma (SCC) is extremely rare in the salivary glands. We report two cases of acantholytic SCC (ASCC) ex PA. Case 1 involved a 72-year-old female, and case 2 involved a 67-year-old male. Histologically, both cases involved PA, and salivary duct carcinoma (SDC) components, which were positive for androgen receptor (AR) and gross cystic disease fluid protein (GCDFP)-15 but negative for HER2, were seen in the intracapsular regions. The invasive components consisted of ASCC, which were positive for cytokeratin 5/6 and p63 but negative for AR and GCDFP-15. The SDC and ASCC components were positive for the epidermal growth factor receptor. In both cases, the cytoplasmic localization or decreased expression of E-cadherin was observed in the ASCC. In the early phase, CXPA might emerge as SDC, and it might change into SCC as it invades beyond the capsule due to changes in microenvironment. Also, the aberrant expression of E-cadherin is related to acantholysis in SCC.

Abstract
Pemphigus is a chronic mucocutaneous disease that initially manifests in the form of intraoral blisters which spread to other mucous membrane and skin. This study describes an unusual case of chronic generalized childhood pemphigus disease in an 11-year-old girl, who presented with multiple vesicles all over her body. Such a condition is seen more often in older people rather than children. It is crucial for dental professionals to be familiar with the diagnosis of bullous skin diseases in children and adolescents, especially in its initial stages in order to prevent the serious consequences and morbidity. The article highlights clinical presentation, histopathology, and successful management strategies useful for pediatric dental practice.

Abstract
Objective: To investigate the clinicopathological features of acantholytic mammary Paget's disease (AMPD). Methods: From January, 2010 to October, 2016, a total of 28 patients were diagnosed as AMPD in the Department of Dermatology, Peking Union Medical College Hospital. The clinical and histopathological data of these patients were analyzed retrospectively. Results: The patients were all female. The mean age of onset was (51±15)years (range, 24 to 78 years). The median course of disease was 10.5 months (range, 3 months to 2 years). All the cases were unilaterally involved. The ratio of left breast involvement to the right breast involvement was 1.55∶1. In histopathological examination, all the cases showed acantholytic pattern. In addition to that, the prototypical pattern accounted for 50.0% (14/28) of all the AMPD cases. The frequencies of other different accompanied histopathological patterns were: 3 (10.7%) upper nest, 2 (7.1%) budding, 1 (3.6%) tall nest, and 1 (3.6%) sheet-like. Hailey-Hailey-disease-like acantholysis was observed in 18 patients (64.3%), whereas pemphigus-vulgaris-like acantholysis was noted in 7 patients (25.0%) and Darier's-disease-like acantholysis in 3 patients (10.7%). About 75.0% (21/28) of the AMPD cases were found to be accompanied with underlying breast cancers. There was no recurrence in 18 of 20 patients who completed treatment and were followed up for over 1 year. Conclusions: AMPD might involve the left breast more frequently. It is mostly associated with the prototypical pattern of mammary Paget's disease. Hailey-Hailey-disease-like acantholysis may be the most frequent subtype of AMPD. Most AMPD cases are associated with underlying breast cancers, but with a low recurrence rate after treatment.

Abstract
Desmoplakin is an essential cytoplasmic plaque protein in desmosomes, and it is the major linker between intercellular junctions in the skin and heart. The role of desmoplakin is anchoring transmembrane cadherins to cytoplasmic intermediate filaments. The desmoplakin gene (DSP) is located on chromosome 6, and six common allelic disorders are associated with this gene, including autosomal-dominant or -recessive disorders that affect the skin, heart, hair, and nails. In particular, lethal acantholytic epidermolysis bullosa (LAEB) is an autosomal recessively inherited and extremely rare genetic skin disorder, and only three molecularly confirmed families with LAEB have been reported previously. Generalized oozing erosion of the entire skin is the main clinical feature, which leads to excessive transcutaneous fluid loss and neonatal death. Histopathologically, this disorder is classified as a suprabasal subtype of epidermolysis bullosa simplex. In this study, we report for the first time in Korea on monozygotic twins with LAEB caused by two novel nonsense mutations in the DSP gene. Both of the twins exhibited severe and rapid progressive whole body skin erosion, and they died shortly after birth because of multiorgan failure followed by excessive fluid loss.

Abstract
Objective: To identify the clinicopathological features of extramammary Paget's disease(EMPD) and investigate the clinical and histopathological significance of acantholysis in EMPD. Methods: From June, 2010 to October, 2016, a total of 56 patients were diagnosed as EMPD in the Department of Dermatology, Peking Union Medical College Hospital. Clinical and histopathological data were retrieved from these patients' medical records and analyzed respectively. The cases were divided into two subgroups according to the histopathological pattern (with or without acantholysis): the acantholytic EMPD (AEMPD) group and the non-acantholytic EMPD (N-AEMPD) group. The clinicopathological data were compared and statistically analyzed between the two groups. Results: The AEMPD group included 22 cases (39.3%), while the N-AEMPD group included 34 cases (60.7%). The male: female ratio, the age of onset, and the median duration of the disease were 10∶1 vs 10.3∶1, (64±8)vs (64±10)years, and 42(4-240)months vs 48(3-120) months in the AEMPD and N-AEMPD groups, respectively, with no significant difference (all P>0.05). There was no significant difference in the severe dermal inflammation (27.3% vs 17.6%, P=0.600 ) and cytologic anaplasia(13.6% vs17.6%, P=0.979)between the AEMPD and N-AEMPD groups.Adnexal involvement or dermal invasion (72.7%) was significantly more common in cases with AEMPD, compared to cases with N-AEMPD (23.5%, P<0.001). And 17 cases in the AEMPD group (77.3%) were Hailey-Hailey-disease-like subtype. The recurrence rate after surgical management (29 cases) showed no significant difference between the two groups (1/12 vs 4/17, P=0.370). Conclusions: Acantholysis is common in EMPD. It is not associated with sex, the age of onset, and the duration of the disease. Acantholysis may indicate invasive growth of Paget's cells. Its occurrence has no association with severe dermal inflammation or cytologic anaplasia. Hailey-Hailey-disease-like subtype is the most common subtype in AEMPD, requiring careful consideration to avoid misdiagnosis. Postoperative recurrence is not associated with acantholysis in EMPD.

Abstract
Aims: Tzanck smear is an old but useful test for diagnosis of cutaneous dermatoses. The aim of this study was to highlight the potential usefulness and diagnostic pitfalls of Tzanck smear for diagnosis of cutaneous dermatoses and infections. Materials and Methods: This hospital based cross-sectional study was carried out on all Tzanck smears received for a period of twenty months (January 2014–August 2015). The smears were assessed to establish the utility of Tzanck smears in corroborating or excluding a diagnosis of immunobullous lesion or herpetic infection. Cases with discrepant diagnosis on histopathology were reviewed to identify additional cytomorphological features. Results: A total of 57 Tzanck smears were performed during the study period. Out of the 18 clinically suspected cases of immunobullous disorders, Tzanck smear findings corroborated the clinical diagnosis in 7/18 cases, one case was diagnosed as cutaneous candidiasis, and diagnosis of immunobullous lesions could be excluded in 5/18 cases. Out of the 19 suspected cases of herpetic infections, viral cytopathic effect was observed in 8/19 cases. Besides immunobullous lesions and herpetic infections, acantholytic cells were also observed in spongiotic dermatitis and genodermatosis. Dyskeratotic keratinocytes seen in vacuolar interface dermatitis were not easily distinguishable from acantholytic cells on Tzanck smear. Conclusions: Tzanck smear test is an inexpensive and useful diagnostic tool for certain skin diseases. It can aid in establishing a rapid clinical diagnosis and can serve as a useful adjunct to routine histological examination. We recommend the use of Tzanck smear as a first-line investigation for vesiculobullous, erosive, and pustular lesions.

Abstract
Pemphigus vulgaris is an autoimmune bullous disease involving both the skin and mucosal areas, which is characterized by intraepithelial flaccid blisters and erosions. The pathogenesis of this disease is not yet completely established, but novel intuitions into its pathogenesis have recently been published. An unanswered question in its pathophysiology is the mechanism of acantholysis or loss of keratinocyte cell adhesion. Acantholysis seems to result from a communal action of autoantibodies against numerous keratinocyte self-antigens, of which desmogleins 1 and 3, desmocollins and nondesmosome components, such as the mitochondrion, might take part in the disease initiation. Lately, apoptosis was described as a possible underlying mechanism of acantholysis. Likewise, apoptolysis is assumed to be the association between suprabasal acantholytic and cell death pathways. Hence, the present review focuses on the current concepts in the pathogenesis of the pemphigus in a nutshell.

Abstract
Pemphigus vulgaris and paraneoplastic pemphigus are 2 subtypes of pemphigus that involve the oral mucosa. These autoimmune blistering disorders have antibodies targeted against proteins of keratinocyte adhesion, thereby causing acantholysis. Clinical findings include oral erosions and flaccid cutaneous bullae and erosions. Further malignancy workup in patients with suspected paraneoplastic pemphigus is warranted. Retrospective uncontrolled studies suggest that immunosuppressive agents reduce mortality in pemphigus vulgaris and cohort uncontrolled studies of rituximab, a monoclonal antibody against CD20, suggest it is an effective treatment for refractory patients. Ongoing studies will define its role in early disease.
