Aim: This paper aims to report a case of minor Erythema Multiforme (EM) triggered by oral amoxicillin, treated with low-level laser applications in the region affected by the disease. Case report: A 12-year-old patient, treated at the Metropolitan Hospital Odilon Behrens, presenting ulcers in the buccal mucosa, lips, tongue, dysphagia, dyslalia, and fever, received a clinical diagnosis of EM and treatment with low-intensity red laser applications, emitted at 660 nm, with a power of 100 mW, with a dose of 33 J/cm² being applied, in points with an approximate distance of 1 cm between them. The lesions resolved within 7 days after treatment were instituted. Conclusion: This present paper shows a successful therapeutic, non-pharmacological alternative for the management of EM, showing the bio stimulating properties of laser in ulcerated lesions of the oral mucosa.

Recurring oral erythema multiforme-like lesions elicited by COVID-19 infection: a case report / Lesões semelhantes a eritema multiforme oral recorrente induzidas por infecção por COVID-19: relato de caso

Oral mucosa could be the first site infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ­the causative agent of coronavirus disease 2019 (COVID-19). Indeed, different oral and paraoral lesions, conditions and symptoms have been reported in patients with COVID-19. Experts thought that such oral lesions could be secondary to the COVID-19-associated deterioration of systemic health or due to treatments of COVID-19. We present here a case of a 24-year-old male presented with painful multiple ulcers involving the labial and buccal mucosae bilaterally after a while of feeling very mild symptoms that laboratory-confirmed by reverse-transcription polymerase chain reaction to be COVID-19. Involvement of eyes was also reported. The above clinical presentation was consistent with minor erythema multiform. Many topical preparations were prescribed but with limited improvement. Hence, oral prednisolone was prescribed with a 40-mg loading dose that was tapered by 10 mg every 3 days. Complete healing of oral mucosa was observed on the 10 day. Strikingly, the patient got affected with the second episode of similar oral lesions 5 months later without any apparent triggering factors, suggestive a long term effects of COVID-19 in a subset of patients. The present case report provides dentists with useful information and increases their awareness regarding possible involvement of oral cavity with multiple ulcerative lesions associated with COVID-19 (AU)

A mucosa oral pode ser o primeiro local infectado com a síndrome respiratória aguda grave coronavírus 2 (SARS- CoV-2) ­ o agente causador da doença por coronavírus 2019 (COVID-19). De fato, diferentes lesões, condições e sintomas orais e paraorais foram relatados em pacientes com COVID-19. Os especialistas pensavam que essas lesões orais poderiam ser secundárias à deterioração da saúde sistêmica associada ao COVID-19 ou devido a tratamentos do COVID-19. Apresentamos aqui um caso de um homem de 24 anos que apresentou múltiplas úlceras dolorosas envolvendo bilateralmente as mucosas labial e bucal após um tempo sentindo sintomas muito leves que foram confirmados laboratorialmente pela reação em cadeia da polimerase de transcrição reversa como COVID-19. O envolvimento dos olhos também foi relatado. A apresentação clínica acima foi compatível com eritema multiforme menor. Muitas preparações tópicas foram prescritas, mas com melhora limitada. Assim, foi prescrito prednisolona oral com uma dose inicial de 40 mg que foi reduzida em 10 mg a cada 3 dias. A cicatrização completa da mucosa oral foi observada no 10º dia. Surpreendentemente, o paciente foi afetado com o segundo episódio de lesões orais semelhantes 5 meses depois, sem nenhum fator desencadeante aparente, sugerindo efeitos de longo prazo do COVID-19 em um subconjunto de pacientes. O presente relato de caso fornece aos dentistas informações úteis e aumenta sua conscientização sobre o possível envolvimento da cavidade oral com múltiplas lesões ulcerativas associadas ao COVID-19 (AU)

Lupus eritematoso asociado a eritema multiforme: Síndrome de Rowell. Reporte del primer caso en Chile

Rowell's syndrome is characterized by an association of lupus erythematosus and erythema multiforme, with distinctive laboratory findings. Its treatment is similar to lupus. We report a 16-year-old female presenting with skin lesions, laboratory and histology consistent with this entity. Because of the spread of cutaneous involvement and development of epidermal detachment, she required therapy with intravenous corticosteroids and gamma globulin.

Unexpected patch test complication: onset of erythema multiforme-like lesions / Complicação inesperada após teste de contato: aparecimento de lesões eritema multiforme-símile

Erythema multiforme is generally associated with infections and drugs. Although less common, there are also reported cases of this disorder after patch testing. We described a 22 year-old female patient who, 24 hours after patch testing, progressed to erythematous iris-shaped plaques and papules with central crust, symmetrically distributed over her hands, arms, and back, with severe itch. The erythema multiforme-like lesions presented in the case were interpreted as a manifestation of systemic allergic contact dermatitis secondary to the exam. Allergic contact dermatitis may be manifested as an erythema multiforme in a hypersensitive person. Few cases of systemic allergic contact dermatitis after patch testing have been reported, for example, due to diethyl thiourea, some textile disperse dyes, and povidoneiodine. The development of erythema multiforme is not noted in most literature references as a complication after patch testing. Although unusual, this disorder needs to be considered as a potential adverse effect of this exam.

O eritema multiforme está associado comumente a infecções e medicamentos. Embora menos comum, também há casos relatados dessa doença após aplicação do teste de contato. Descrevemos uma paciente de 22 anos que evoluiu, em 24 horas após o teste, com placas e pápulas eritematosas, em formato de íris e crosta central, distribuídas simetricamente nas mãos, braços e costas, além de prurido intenso. As lesões eritema multiformesímile presentes no caso foram interpretadas como uma manifestação alérgica secundária ao exame. Dermatite de contato alérgica pode se manifestar como um eritema multiforme em pessoas hipersensíveis. Poucos casos de dermatite alérgica de contato sistêmica foram relatados após este exame, por exemplo, devido às seguintes substâncias: dietil tioureia, corantes dispersos têxteis e iodopovidona. O desenvolvimento do eritema multiforme não é usualmente apontado como uma complicação do teste de contato alérgico, na maioria das referências literárias. Embora incomum, o surgimento dessa desordem após este exame necessita ser considerado como um efeito adverso.

Eritema multiforme limitado à cavidade oral em um cão: relato de caso / Multiforme erythema limited to the oral cavity in a dog: case report

O eritema multiforme é uma doença incomum em cães, que afeta pele e mucosas, cuja etiologia ainda não foi completamente elucidada. Contudo, o envolvimento exclusivo da cavidade oral é considerado raro, tendo sido descrito poucas vezes até o presente momento. O objetivo deste trabalho é descrever um caso de eritema multiforme limitado à cavidade oral em um canino. Um cão, fêmea, Akita, com sete anos de idade, apresentou histórico de ulcerações na cavidade oral e nas laterais da língua, sem alterações cutâneas ou sistêmicas. O diagnóstico definitivo foi realizado por meio do exame histopatológico da mucosa oral, e a terapia imunossupressora empregada mostrou-se eficaz. Embora o eritema multiforme seja considerado incomum na espécie canina, este relato de caso apresenta a forma mais rara da doença, com poucos casos descritos em medicina veterinária.(AU)

Multiforme erythema is an uncommon disease in dogs that affects the skin and mucous membranes, the etiology of which has not yet been fully elucidated. However, the exclusive involvement of the oral cavity is considered rare, having been described few times until the present moment. The aim of this work is to describe a case of multiforme erythema limited to the oral cavity in a canine. A seven-year-old female dog, akita, presented a history of ulcerations in the oral cavity and on the sides of the tongue, with no cutaneous or systemic changes. The definitive diagnosis was made through the histopathological examination of the oral mucosa and the immunosuppressive therapy used proved to be effective. Although multiforme erythema is considered uncommon in the canine species, this case report presents the rarest form of the disease, with few cases described in veterinary medicine.(AU)

El Eritema Multiforme (EM) es una reacción poco común, aguda, de piel y mucosa. Es una reacción de hipersensibilidad, caracterizada por erupciones en piel en forma de diana, constituidas por zonas concéntricas de diferente coloración, y lesiones ulcerosas o vesículo-ampollares en mucosa. La enfermedad puede ser desencadenada por infecciones, principalmente por virus del herpes simple (HSV) y Mycoplasma pneumoniae y por ingestión de drogas, siendo las más frecuentes las sulfonamidas y las penicilinas. Se presentan tres casos relacionados a la infección por el virus del herpes simple.

Erythema multiforme (EM) is a condition acute, mucocutaneous, caused by hypersensitivity reaction, characterized by skin eruption (target lesions with concentric zones) and mucous membrane lesions (ulcerous, bullous-vesicular lesions). The disorder can be induced by infections, particularly herpes simplex(VSH) and Mycoplasma pneumoniae, or by drug intake (AINE, sulfonamides, penicillin’s) Three cases related to VHS infection, are presented.

Síndrome de Stevens-Johnson associada à alopurinol e nimesulida: relato de caso / Stevens-Johnson Syndrome associated with allopurinol and nimesulide: case report

A síndrome de Stevens-Johnson (SSJ) é uma variante do eritema multiforme pela conformação e distribuição das lesões cutâneas e maior gravidade do envolvimento mucoso. É caracterizada pela ação de anticorpos IgG ou IgM específicos para drogas. Apresenta importante papel na Odontologia pois que muitas vezes as primeiras manifestações desta doença ocorrem na mucosa bucal. O objetivo deste trabalho é apresentar um relato de um paciente portador da SSJ, sexo masculino, 53 anos, com queixa inicial de dor e ardência bucal. Ao exame clínico verificou-se lesões e crostas hemorrágicas evidentes no vermelhão dos lábios e mucosa bucal. Relatou que foi atendido anteriormente em um serviço oftalmológico e diagnosticado com conjuntivite e que estava sob uso das seguintes medicações: alopurinol, nimesulida, sinvastatina, omeprazol e frontal. O quadro do paciente evoluiu rapidamente para as lesões em pele e por esta razão internado e submetido a protocolo do setor de queimados de um hospital particular. Atualmente o paciente apresenta as seguintes sequelas: cegueira do olho esquerdo, simbléfaro e pterígio nasal. O conhecimento dessa síndrome, pelo cirurgião-dentista é de fundamental importância, vez que, o estabelecimento do diagnóstico precoce pode minimizar as sequelas e até mesmo evitar casos extremos de óbito. Por fim, esclarecer e conscientizar os profissionais quanto ao uso indiscriminado de medicamentos, causa hoje reconhecida para esta síndrome... (AU)

The Stevens-Johnson syndrome (SJS) is a variant of erythema multiforme by the conformation and distribution of skin lesions and more severe mucosal involvement. It is characterized by the action of specific drugs for IgG or IgM antibodies. Plays an important role in dentistry since often the first manifestations of this disease occur in the oral mucosa. The objective of this paper is to present a report of a patient with SJS, male, 53 years, with an initial complaint of pain and burning mouth. On clinical examination there was injury and hemorrhagic crusts evident in the vermilion of the lips and buccal mucosa. Reported that previously serviced on an eye care center and diagnosed with conjunctivitis and was under use of the following medications: allopurinol,nimesulide, simvastatin, omeprazole and front. The patient's condition progressed rapidly to skin lesions and for this hospital and subjected to the burning of a private hospital sector protocol reason. Currently the patient has the following consequences: blindness of the left eye, nasal pterygium and symblepharon. Knowledge of this syndrome, the dentist is crucial, since the establishment of early diagnosis can minimize sequelae and even prevent extreme cases death. Finally, clarify and educate professionals about the indiscriminate use of medicines, now recognized to cause this syndrome... (AU)

An atypical presentation of erythema elevatum diutinum

Erythema elevatum diutinum is a rare chronic leukocytoclastic vasculitis of unknown etiology. Lesions are usually asymptomatic, although burning and itchiness can occur. The typical clinical presentation is characterized by persistent, symmetrical,papules and nodules that may coalesce to form larger nodules or plaques. It may be associated with various pathologies and the diagnosis is based on clinical and histopathological findings. Treatment is based on the use of dapsone and sulfonamides, first-line therapies, and other options such as niacinamide, tetracycline,colchicine, chloroquine and corticosteroids. We describe the case of a 65-year-oldmale patient that presented a single lesion on the dorsum of the hand, an unusual clinical presentation.

Erythema multiforme in leprosy

The clinical course of leprosy is often interrupted by reactions, which are acute inflammatory episodes that can be classified as type I or type II. Type II reactions can present as cutaneous lesions that resemble erythema multiforme (EM). EM is classically associated with drug allergies or pre-existing viral infections. However, the differential diagnostic criteria of the diverse causative agents remain controversial. The aim of this study was to determine both the clinical relevance and the morphological and immunohistochemical characteristics of the EM-like lesions during the course of type II leprosy reactions. Twenty-seven skin biopsies were taken from typical EM-like lesions of multibacillary patients and reviewed; their histological features were correlated to their clinical aspects. Then, a computer-assisted morphometric analysis was performed to measure the extent of angiogenesis during these acute episodes. The histopathological and immunohistochemical analysis of the EM lesions revealed that they shared the same features that have been previously described for ENL, including immunopositivity in the identical cell-mediated immune markers. Our results point to leprosy as the cause of the EM-like lesions in our patients. Therefore, leprosy should be considered in the differential diagnosis of EM.

Síndrome de Stevens-Johnson: presentación de un caso / Stevens-Johnson syndrome: a case presentation

El síndrome de Stevens-Johnson, también llamado eritema multiforme mayor, se caracteriza por una serie de lesiones cutáneas de diversa morfología, es una grave lesión en la cual están afectadas al menos dos membranas mucosas y la piel. La patogenia de esta enfermedad es desconocida aunque generalmente se considera que es provocada por una reacción de hipersensibilidad a drogas, infecciones y exposición a sustancias tóxicas. Caso clínico: esta afección fue diagnosticada en un niño africano de nueve años de edad. El niño desarrolló una severa y florida forma de ulceración mucocutánea, manifestaciones orales y oculares serias, marcados trastornos sistémicos y deshidratación. Se realizó una amplia revisión bibliográfica sobre el tema donde fueron verificadas las manifestaciones clínicas, evolución y el tratamiento de esta enfermedad.

Stevens-Johnson syndrome also called erythema multiforme major, it is characterized by a series of cutaneous lesions with different morphology, and it is a serious lesion in which two mucous membranes and skin are affected at least. The pathogeny of this disease is ignored although it is generally considered that it is caused by a drug hypersensitivity reaction, infections and exposure to toxic substances. Clinical case: this affection was diagnosed in a nine year-old African boy. The boy developed a severe and florid form of mucocutaneous ulceration, serious oral and ocular manifestations, marked systemic disorders and dehydration. A wide bibliographical review on the topic was carried out where clinical manifestations, evolution and treatment of this disease were verified.

A importância das provas epicutâneas de contacto no diagnóstico diferencial de reações a medicamentos / The importance of patch tests in the differential diagnosis of adverse drug reactions

O eritema exsudativo multiforme é uma erupção aguda, autolimitada, frequentemente associada a infecções (geralmente virais), doenças sistêmicas e fármacos. Apresenta-se o caso de uma mulher de 39 anos, com o diagnóstico de lúpus eritematoso sistêmico, que recorreu à Urgência com quadro de eritema exsudativo multiforme, com início 10 dias após tomar amoxicilina e ácido clavulânico por amigdalite e, quase simultaneamente, receber a vacina antipneumocócica. Colocou-se também a hipótese de síndrome de Rowell. Efetuaram-se testes epicutâneos de contacto com bateria básica (portuguesa) e princípios ativos dos fármacos suspeitos (Chemotechnique®). Encontrou-se hipersensibilidade à amoxicilina 10 por cento vas (++), à ampicilina 10 por cento vas (++) e à penicilina G potássica 10 por cento vas (+), atribuindo-se à amoxicilina a causa mais provável do eritema exsudativo multiforme.

Exudative erythema multiforme is an acute self-limited skin disease often associated with infections (usually viral), and also with systemic diseases and drugs. We report the case of a 39-year-old woman diagnosed with systemic lupus erythematosus, who presented at the emergency clinic with exudative erythema multiforme which started 10 days after taking amoxicillin and clavulanic acid for tonsillitis together (almost simultaneously) with the pneumococcal vaccine. Rowell's syndrome was also considered to be a possibility. Skin patch tests were carried with the standard battery of patches (GPEDC) and the active ingredients of the suspected drugs (Chemotechnique ®), with readings at D2 and D3. The tests were positive for amoxicillin 10 percent pet (++), ampicillin 10 percent pet (+ +) and penicillin G potassium 10 percent pet (+). We accepted the diagnosis of erythema multiforme due to amoxicillin, confirmed by patch testing.

Complications of post-operative seizure prophylaxis in patients submitted to cranial irradiation

The clinical status of patients with malignant intracranial tumors, such as high-grade gliomas, is often aggravated by seizure activity. Phenytoin is typically employed as prophylactic anticonvulsant in this setting. In such patients, severe systemic drug reactions such as erythema multiforme (EM) may occur. However, in a subgroup of patients with brain radiation therapy, EM-like lesions appear to develop in an increased ratio. The acronym ‘EMPACT’ (E: erythema; M: multiform; associated with P: phenytoin; A: and; C: cranial, radiation; T: therapy) has been suggested to best describes this syndrome. In this article, the authors present a case report of a patient treated with phenytoin for seizure prophylaxis, during the post-operative period following resection of a malignant glioma, and who presented a severe cutaneous rash, evolving with serious consequences due to abrupt change of seizure medications. Because of these predictable complications we abandoned our routine institutional protocol which employed phenytoin for seizure prophylaxis for patients in the post-operative period following malignant tumor resection and which expect to be irradiated in the near future. Once both carbamazepine and barbiturates show cross-sensitivity with phenytoin and may interfere with serum levels of chemotherapy drugs, we now advocate, as other worldwide renown neuro-oncological centers, the use of valproate gabapentin, or alternatively, as recent literature guidelines suggests levetiracetam (keppra), for seizure prophylaxis in this select subset of patients.

El estado clínico de los pacientes con tumores malignos intracraneales, como los gliomas de alto grado, es a menudo agravado por la actividad convulsiva. La fenitoína es normalmente empleadaa como anticonvulsivante profiláctico en esto contexto. En estos pacientes, graves reacciones sistémicas, como eritema multiforme (EM) puedem ocurrir. Sin embargo, en un subgrupo de pacientes con terapia de radiación en el cerebro, lesiones de EM, parece que se desarrollan en una proporción mayor. ‘EMPACT’ La sigla (E: eritema, M: multiforme; asociados con P: fenitoína; A: y C: la radiación craneal, T: La terapia) Se ha sugerido que mejor describe este síndrome. En esto artículo, los autores presentan un caso clínico de un paciente tratado con fenitoína para la profilaxia de convulsiones, durante el período post-operatorio después de la resección de un glioma maligno, y que presenta una erupción cutánea grave, que evoluciona con consecuencias graves debido al cambio brusco de medicamentos anticonvulsivos. Debido a estas complicaciones predecibles, que abandonamos nuestro protocolo institucional de rutina que la fenitoína empleadas para la profilaxia de convulsiones en los pacientes en el período post-operatorio después de la resección del tumor maligno y que esperan ser irradiado en un futuro próximo. Una vez que ambos carbamazepina y los barbitúricos mostran sensibilidad cruzada con fenitoína y puede interferir con los niveles séricos de drogas de la quimioterapia, ahora defendemos, como otros centros de renombre mundial neuro-oncológico, el uso de gabapentina valproato, o bien, como orientación la literatura reciente sugiere levetiracetam (keppra), para la profilaxia de las convulsiones en este subgrupo seleccionado de pacientes.

Reacciones cutáneas adversas a anticonvulsivantes y estabilizadores del ánimo / Adverse cutaneous reactions to anticonvulsants and mood stabilizers

Anticonvulsivantes y estabilizadores del ánimo principalmente el ácido valproico, lamotrigina y carbamazepina, poseen una alta incidencia de reacciones adversas a medicamentos (RAM) severas, como eritema multiforme, Síndrome Stevens- Johnson y necrolisis epidérmica tóxica, asociadas. Existen signos de alarma para su sospecha diagnóstica precoz, que permiten indicar la temprana suspensión del fármaco sospechoso e iniciar la terapia de soporte únicas medidas que han demostrado una clara disminución en la mortalidad. La inmunoglobulina G intravenosa se recomienda por su seguridad, sin embargo, su rol en disminuir la mortalidad es contradictorio. Los corticoides no han demostrado cambios en la mortalidad comparados con la terapia de soporte exclusiva. Se ha intentado mantener el tratamiento con lamotrigina, por sus cualidades terapéuticas, pese a la aparición de RAM cutáneas. De hecho, en estudios recientes en pacientes que han desarrollado RAM leves a este producto se ha demostrado un éxito de reexposición de 85 por ciento-87 por ciento mediante una lenta titulación de la dosis.

Anticonvulsants and mood stabilizers mainly valproic acid, lamotrigine and carbamazepine are medications that have a high incidence of severe adverse drug reactions (ADRs), such erythema multiforme, Stevens- Johnson syndrome and toxic epidermal necrolysis. Early diagnosis based in systemic and cutaneous alarm signs have been described, allowing premature discontinuation of suspected drugs and start supportive therapy; these are the only measures that have that have shown clear reduction in mortality. The use of intravenous immunoglobulin G is recommended for their safety, but studies regarding their role in reducing mortality are conflicting. Corticosteroids have not proved changes in mortality compared with exclusive supportive care. Due to therapeutic quality Lamotrigine is used despite the incidence of ADRs. In fact in recent studies patients with mild ADRs to this drug have shown between 85 percent-87 percent of success, when patients are re-exposed through a slow increasing in dosage.
