Oral lesions after infection by SARS CoV 2: two case reports / Lesiones bucales posteriores a infección por SARS CoV 2 presentación de dos casos

Introduction: The SARS CoV 2 infection has resulted in several health, economic, and social crises in all areas. The disease shows a substantial biological diversity in humans causing a series of sequels in the trans- or post-infection period in the entire organism. Case Report: The manifestations that occur in the oral cavity and pharynx have not been evaluated. In this study, two clinical cases are reported. The first patient, a 67-year-old male, presents erosive lesions on the dorsal surface of his tongue after SARS CoV 2 infection. Results: Therapy consisting of reinforcing oral cleaning, use of antifungal solutions, mouthwashes containing superoxidation solution and B complex was given to the patient. The reported lesions improved satisfactorily. The second case, a 47-year-old male patient, presented vesiculobullous lesions on the lingual and labial mucosa accompanied by severe painful symptoms after SARS CoV 2 infection. An incisional biopsy was performed. The histopathological result was compatible with pemphigus vulgaris, and the treatment protocol was started with 0.1% topical mometasone and 2g miconazole gel, observing adequate involution of the lesions after 20 days. Conclusions: The aim of this study is to report on the lesions affecting the oral cavity and pharynx in post-COVID patients with the aim of carrying out a thorough intraoral examination, establishing a clinical or histopathological diagnosis to implement a specific treatment plan in each case to improve the health and quality of life of the patients. Keywords: SARS-CoV-2; Oral manifestations; Oral ulcer; Pemphigus; Mouth; Mucous membrane.

Reporte de Caso: Se ha evaluado poco las manifestaciones que se presentan en la cavidad bucal y faringe; se presentan dos casos clínicos el primero paciente masculino de 67 años de edad posterior a la infección por SARS CoV 2 presenta diluciones de continuidad en bordes laterales de la lengua se indica terapia y refuerza limpieza bucal, antimicótico, colutorios con solución de superoxidación y complejo B, las úlceras involucionan de manera satisfactoria. Resultados: El segundo caso masculino de 47 años posterior a la infección por SARS CoV 2 debuta con lesiones vesículo-ampollosas en mucosa lingual, labial con sintomatología dolorosa severa, se realiza biopsia incisional donde el resultado histopatológico es compatible con pénfigo vulgar, se inicia protocolo de tratamiento con mometasona tópica al 0.1% y miconazol gel 2g observándose una adecuada involución de las lesiones a los 20 días. Conclusiones: El objetivo de este trabajo es poner en contexto de la comunidad médica y científica las lesiones concernientes a la cavidad bucal y faringe que están presentando los pacientes postcovid con el objetivo de realizar una exhaustiva exploración intraoral, establecer un diagnóstico clínico o histopatológico y con base en esto instaurar un plan de tratamiento específico en cada caso en particular con el fin fundamental de mejorar la salud y calidad de vida del paciente.

Psoriasis vulgaris with Pemphigus Foliaceus treated with methotrexate: A case report

@#Psoriasis is a systematic immune-mediated inflammatory disease where there is an increased cell turnover of the skin leading to scaling, drying, and erythema. The occurrence of pemphigus foliaceus, an autoimmune blistering disease (AIBD) characterized by flaccid bullae and erosions, is rare when concomitantly present with psoriasis. Treatment options for these diseases may overlap. We report a case of a 44-year-old female who presented with both psoriasis and pemphigus foliaceus successfully treated with methotrexate.

Pemphigus foliaceus in a 51-year-old female

@#Pemphigus foliaceus (PF) is a chronic, benign, acquired autoimmune blistering disease characterized by fragile, superficial blisters and bullae.1 2 3 Patients commonly report blister formation on the skin, followed by localized lesions that typically begin on the trunk, face, or scalp.2 PF is a rare disease with a very low worldwide incidence and prevalence. However, it has a high incidence in endemic areas located in North Africa, Brazil, Colombia, and Peru.2 3 4 The disease affects both sexes equally, with symptoms typically appearing between the ages of 50 and 60 years.2 4 The universal type of PF that occurs sporadically is idiopathic, while the endemic type is linked exclusively to geographically-related environmental factors.

Pénfigo vulgar y su manejo integral: reporte de dos casos y revisión de literatura / Pemphigus Vulgaris and its Comprehensive Management: Report of Two Cases and Literature Review

Resumen En la cavidad oral se pueden presentar lesiones en gíngiva que no están asociadas a placa bacteriana, las cuales requieren de un adecuado diagnóstico y tratamiento. La gingivitis descamativa está usualmente relacionada con desórdenes mucocutáneos, como el pénfigo vulgar (PV), donde las lesiones orales incluyendo las lesiones gingivales, pueden preceder las lesiones cutáneas. El manejo es multidisciplinario y el tratamiento incluye terapia farmacológica tópica y sistémica, se requiere un adecuado control de la placa bacteriana por parte del paciente y una estricta supervisión en el tiempo por parte del profesional para el mantenimiento y estabilidad de los tejidos gingivales. Se presentan dos casos clínicos de pacientes con diagnóstico de PV los cuales fueron manejados de manera oportuna e integral para controlar y estabilizar el factor sistémico y local.

Abstract In the oral cavity, gingiva lesions may occur that are not associated with bacterial plaque, which require adequate diagnosis and treatment. Desquamative gingivitis is usually related to mucocutaneous disorders, such as pemphigus vulgaris (PV), where oral lesions, including gingival lesions, may precede skin lesions. Management is multidisciplinary and treatment includes topical and systemic pharmacological therapy, require adequate control of dental plaque by the patient and strict supervision over time by the professional for the maintenance and stability of the gingival tissues. Two clinical cases of patients with a diagnosis of PV are presented, which were managed in a timely and integral way to control and stabilize the systemic and local factor.

Desquamative Gingivitis as the First Clinical Sign of Pemphigus Vulgaris: A Case Report

ABSTRACT@#Desquamative gingivitis is characterised by desquamation of the gingiva with painful erosion and ulceration. It is predominantly a manifestation of several vesiculobullous diseases. Delayed diagnosis or misdiagnosis often led to disease progression. Pemphigus vulgaris is a chronic, life-threatening autoimmune disease resulting in blistering of the mucosa and skin. Oral lesions normally preceded skin lesions. Early diagnosis and treatment are important to prevent involvement of the skin, as the treatment and prognosis varies with extraoral involvement. Clinical, histopathological examination and direct immunofluorescent are necessary for the diagnosis of pemphigus vulgaris. Treatment of desquamative gingivitis involves improving oral hygiene, reduce irritation to the lesions and specific therapy to the underlying disease. This paper describes a case of a patient with desquamative gingivitis for one year, whom is ultimately diagnosed as having pemphigus vulgaris.

Pénfigo vulgar con afectación exclusiva en el esófago: reporte de un caso / Pemphigus vulgaris with exclusive affectation in the esophagus: a case report

Introducción: el pénfigo vulgar comprende un grupo de enfermedades heterogéneas autoinmunes ampollosas de la piel y las mucosas. La afectación esofágica en el pénfigo vulgar es rara, con una prevalencia incierta que requiere un abordaje diagnóstico y terapéutico detallado. Caso clínico: mujer de 37 años, con antecedentes de tratamiento con inhibidores de la Cox-2 debido a hernia discal. Se envió a Gastroenterología por pérdida de peso de aprox. 5kg en un mes. La paciente tuvo presencia de disfagia, odinofagia y dolor retroesternal con pobre tolerancia a la vía oral. Se hizo endoscopía que reportó esofagitis disecante superficial y gastropatía eritematosa de antro; el duodeno estaba en estado normal. Los hallazgos se correlacionaron con el diagnóstico de pénfigo vulgar con afectación exclusiva a esófago. En la valoración no se identificaron lesiones en piel, cavidad oral u otras mucosas. Se hizo nueva endoscopía como control y se encontró inmunofluorescencia de biopsia esofágica reactiva a IgG 2. Se dio manejo inicial con glucocorticoides, antiinflamatorios e inmunosupresores. Conclusiones: la importancia del estudio del pénfigo radica no solo en la alta morbimortalidad asociada, sino en lo raro y complejo de su detección, pues los pacientes suelen tardar varios meses en tener un diagnóstico certero y aún más en conseguir las metas terapéuticas. Es prioritaria la difusión del estudio del pénfigo entre los profesionales de lasalud involucrados en su detección.

Background: Pemphigus vulgaris comprises a group of heterogeneous blistering autoimmune diseases of the skin and mucosa. Esophageal involvement within pemphigus vulgaris is rare with an uncertain prevalence that requires a detailed diagnostic and a therapeutic approach. Clinical case: 37-year-old female, with a history of treatment with Cox-2 inhibitors due to herniated disc. She is sent to the Gastroenterology Service for weight loss of approximately 5 kilos in a month, with the presence of dysphagia, odynophagia and retrosternal pain with poor toleranceto the oral route. Endoscopy was performed, which reported esophagitis dissecans superficialis (EDS), erythematous gastropathy of the antrum and normal duodenum. Findings were correlated with the diagnosis ofpemphigus vulgaris with exclusive involvement of the esophagus. The evaluation did not identify lesions on the skin, oral cavity or other mucous membranes. A new endoscopy was performed as a control and it was found immunofluorescence of the esophageal biopsy reactive to IgG 2. Initial management was given with glucocorticoids, anti-inflammatories and immunosuppressants. Conclusions: The importance of the study ofpemphigus lies not only in the high associated morbidity and mortality, but also in its intrinsic rarity and the complexity of its detection, given that patients usually take several months to have an accurate diagnosis and even more time to achieve therapeutic goals. It is a priority the dissemination of the study of pemphigus among health professionals involved in its detection.

An unusual presentation of painless penile erosions of pemphigus vulgaris: A case report

Introduction@#Pemphigus vulgaris is a life-threatening, autoimmune bullous disease caused by desmogleins (Dsg) 1 and 3 au- toantibodies. It is a rare disease with an incidence rate of 0.5 to 3.2 per 100,000 per year. It typically presents as painful, flaccid blisters and erosions on both the skin and mucous membranes.@*Case report@#We present a 43-year-old male with painless penile erosions of 1-month duration. He was evaluated for sexually transmitted infections, but laboratory tests yielded negative results. Subsequently, vesicles and bullae on the back and hyper- keratotic lesions on the malar area appeared, leading to the differential diagnoses of bullous diseases. Skin biopsy was done revealing intraepidermal suprabasal blisters with acantholytic cells. Direct Immunofluorescence demonstrated positive inter- cellular deposits of IgG and C3. ELISA Dsg 1 and Dsg 3 were positive (ratio of 1.857 and 4.580, respectively). A final diagnosis of pem- phigus vulgaris (PV) was made. The patient has remained in remission after a 3-month course of prednisone and azathioprine.@*Conclusion@#This is a unique case of PV presenting with an unusual manifestation of painless penile erosions. There have been limited reports of PV with penile skin involvement and all cases presented with painful lesions. Because painless penile lesions as presenting feature is rare, the diagnosis may be easily missed. This case demonstrates that thorough dermatologic examination and early diagnosis despite atypical findings are crucial to provide timely and appropriate treatment as this determines the clinical outcome of the disease.

Recién nacido con pénfigo sifilítico en tiempos de pandemia / Newborn with syphilitic pemphigus in pandemic's time

Resumen La sífilis congénita es la infección del recién nacido (RN) por Treponema palllidum transmitida durante el embarazo desde la madre al feto. Actualmente, sigue siendo una causa importante de morbi-mortalidad fetal prevenible en todo el mundo, pese a que con un tratamiento adecuado y oportuno en la madre, se logra revertir en forma efectiva los resultados adversos en el feto y RN. Lo anterior destaca la importancia del control del embarazo, y la pesquisa precoz de la infección materna. Si bien, Chile ha experimentado un aumento de la incidencia de sífilis en la población general, se ha mantenido una tasa estable de sífilis congénita de 0,1 por 1.000 RN vivos. Presentamos el caso clínico de un RN, hijo de una madre sin control del embarazo, que presentó lesiones compatibles con un pénfigo sifilítico.

Abstract Congenital syphilis is the infection by Treponema pallidum of the newborn, due to mother-to-child transmission of spirochaetes during pregnancy. It remains as a major cause of preventable fetal and neonatal morbidity and mortality if the mother is not opportunely treated. This highlights the importance of an adequate prenatal control, early screening for maternal infection and timely treatment. Although Chile has experienced an increase in the incidence of syphilis in the general population, a stable rate of congenital syphilis in 0.1/1.000 live births has been maintained. In this case report, we present a newborn whose mother did not have antenatal control and showed dermatological lesions compatible with syphilitic pemphigus.

Pénfigo foliáceo de presentación inusual / Penphigus foliaceus of unusual presentation

Si bien las enfermedades ampollares autoinmunes son infrecuentes en la infancia y la juventud, es importante tenerlas en cuenta dentro del diagnóstico diferencial, junto con otras enfermedades inflamatorias o infecciosas de mayor prevalencia, para lograr un diagnóstico temprano y así indicar el tratamiento preciso y oportuno. El pénfigo foliáceo es una enfermedad ampollar poco común, salvo en la zona endémica de Brasil. Se presenta un caso de pénfigo foliáceo con eritrodermia como cuadro clínico con mala evolución (AU)

Although autoimmune bullous diseases are infrequent in childhood and youth, it is important to take them into account within the differential diagnosis, along with other more prevalent inflammatory or infectious diseases, to achieve an early diagnosis and thus indicate precise and timely treatment. Pemphigus foliaceus is a rare autoimmune bullous diseases, except in the endemic area of Brazil. This case report presents a patient with the unusual erythrodermic presentation of pemphigus with poor evolution (AU)

Estigmas, pesquisas e embates: uma história do pênfigo brasileiro, séculos XIX e XX / Stigmas, studies, and strife: a history of Brazilian pemphigus, nineteenth and twentieth centuries

Resumo O artigo apresenta uma narrativa histórica sobre a incidência do pênfigo foliáceo no Brasil ao longo dos séculos XIX e XX. Doença bolhosa autoimune da pele que acomete com mais frequência crianças, adolescentes e adultos jovens que vivem nas áreas rurais de regiões endêmicas. Foi descrita pela primeira vez no país em 1903, pelo médico Caramuru Paes Leme. Os principais focos se situam no Distrito Federal e nos estados de Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná e São Paulo. Temática de pesquisa amplamente visitada pela ciência médica, em especial a dermatologia, não tem merecido a atenção peculiar por parte dos historiadores da saúde e da doença.

Abstract This paper presents a historical narrative about the incidence of pemphigus foliaceus in Brazil in the nineteenth and twentieth centuries. This autoimmune blistering skin disease is more common in children, adolescents, and young adults who live in rural areas of endemic regions. It was first described in Brazil in 1903 by the physician Caramuru Paes Leme. The main foci of the disease are in the Federal District and the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, and São Paulo. This research topic, which has attracted widespread attention from medical practice, especially dermatology, has not received similar attention from historians of health and disease.

Present tense: A peculiar case of Pemphigus Vulgaris presenting with tense blisters during the COVID-19 pandemic

@#Pemphigus vulgaris is an autoimmune bullous dermatosis presenting with flaccid blisters and erosions. The morphology of pemphigus reflects the more superficial intraepidermal level of split seen histologically in contrast with pemphigoid, where the level of split is deep below the epidermis. This is a case of a 58-year-old male clinically presenting with arcuate tense bullae, which are more characteristic of the pemphigoid group of disorders, which revealed an intraepidermal split and tombstoning pattern of the basal epidermis on histopathology. Direct immunofluorescence revealed intercellular IgG and C3 distribution. Although this patient presented clinically with tense bullae, the histopathology and direct immunofluorescence results were consistent with pemphigus vulgaris.

Rituximab as First-line Therapy for Severe Pemphigus: A Case Series and Review of Current Literature

Summary@#Pemphigus refers to a group of life-threatening, autoimmune blistering disease that presents as blisters and erosions involving the skin and mucosa. Systemic corticosteroids and rituximab have been recommended as mainstay therapy for pemphigus vulgaris and pemphigus foliaceus. Herein, we report three cases of pemphigus vulgaris and a case of pemphigus foliaceus treated with rituximab as first-line therapy.

Childhood pemphigus vulgaris is a challenging diagnosis

Pemphigus Vulgaris (PV) is an uncommon autoimmune and blistering mucocutaneous disease. Childhood Pemphigus Vulgaris (CPV) is a pediatric variant of PV, which affects children below 12 years, being very rare among children under 10 years of age. CPV has similar clinical, histological, and immunological features as seen in PV in adults. The mucocutaneous clinical presentation is the most common in both age groups. Vesicles and erosions arising from the disease usually cause pain. A few CPV cases have been reported in the literature. This study reports a case of an 8-year-old male patient with oral lesions since the age of 3 years, and the diagnosis of pemphigus was achieved only 2 years after the appearance of the initial lesions. CPV remains a rare disease, making the diagnosis of this clinical case a challenge due to its age of onset and clinical features presented by the patient. Therefore, dentists and physicians should know how to differentiate CPV from other bullous autoimmune diseases more common in childhood.

Experience in the diagnosis and treatment of a drug-induced pemphigus / 华西口腔医学杂志

Drug-induced pemphigus (DIP) is a special type of pemphigus, and its pathogenesis, characteristics of treatment, and prognosis are closely related to the inducing drugs. This article reports the diagnosis and treatment of DIP (pemphigus vulgaris) caused by the administration of rifampin to a patient with tuberculosis. Combined with the literature, we discussed the types, pathogenesis, differential diagnosis, and treatment principles of DIP. We propose that in the oral clinical practice for patients with pemphigus vulgaris, the importance of investigating suspected drugs that induce DIP should be emphasized.

Clinical Analysis of Eight Cases of Pemphigus with High Titers of Anti-desmoglein Antibodies in Remission / 中国医学科学院学报

Objective To investigate the clinical manifestations,diagnosis,treatment,and laboratory examination characteristics of 8 pemphigus patients with high titers of anti-desmoglein antibodies in remission. Methods A retrospective study was conducted for the pemphigus patients diagnosed and treated in the department of dermatology from January 2013 to September 2020.The patients should have the serum anti-desmoglein antibodies ≥150 U/ml in remission or the antibody levels dropped less than 20%(calculated based on the maximum detection limit of 150 U/ml)of their initial ones detected before treatment,and the clinical and laboratory data of patients eligible for the inclusion criteria were collected. Results Among the 134 pemphigus patients with available follow-up data during this period,a total of 8 patients met the criteria,with the follow-up period of 21-85 months and the remission duration of 18-70 months.They all received less than or equal to 10 mg/d prednisone and had high titers of anti-desmoglein antibodies.At their first visit,the number of patients with positive anti-desmoglein 1/desmoglein 3 antibodies was 7.Two patients still had high titers of anti-desmoglein 1 antibodies 19 months and 21 months after they achieved remission,and 5 patients had high titers of anti-desmoglein 3 antibodies in 18-70 months.There was one patient showing high titers of both antibodies,especially for anti-desmoglein 1 antibodies.This patient relapsed after 19 months' remission while other patients were still in clinical remission. Conclusions Some pemphigus patients showed persistent high titers of anti-desmoglein antibodies in remission.Anti-desmoglein 3 antibodies were more common to keep positive,while high titer of anti-desmoglein 1 antibodies was less observed.The high titer of anti-desmoglein 1 antibodies had a correlation with recurrence.For the pemphigus patients with long-term clinical remission but high antibody titer,the dosages of corticosteroids should be adjusted carefully according to their actual clinical manifestations and the positive antibody type.For the patients with high titer of anti-desmoglein 1 antibodies,the dosage reduction of corticosteroids should be appropriately slower.
