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)

Moxifloxacin-induced oral erythema multiforme: An unusual adverse effect hitherto unreported.

Moxifloxacin is a fluoroquinolone with excellent activity in community-acquired respiratory tract infections. Common adverse effects are gastrointestinal symptoms, headache, dizziness, etc., Some serious adverse effects include tendon rupture, rhabdomyolysis, peripheral neuropathy, and interstitial nephritis. Cutaneous adverse effects include allergic reactions, angioedema, Steven-Johnson syndrome, and toxic epidermal necrosis. Erythema multiforme (EM), an acute self-limiting disease, most commonly occurs due to infection and rarely due to drugs or systemic disease. EM is classified into EM major and minor, both having skin lesions. A third category of EM has also been described with only oral involvement and without any skin lesions. Oral EM itself is an uncommon entity which has been reported due to nonsteroidal anti-inflammatory drugs. Here, we are reporting a case of moxifloxacin-induced oral EM. After extensive search in PubMed-Medline database, we could not find any such co-occurrence of moxifloxacin-induced oral EM. To the best of our knowledge, this is the first reported case.

Ulcerated Lesions of the Oral Mucosa: Clinical and Histologic Review.

Ulcerated lesions of the oral cavity have many underlying etiologic factors, most commonly infection, immune related, traumatic, or neoplastic. A detailed patient history is critical in assessing ulcerative oral lesions and should include a complete medical and medication history; whether an inciting or triggering trauma, condition, or medication can be identified; the length of time the lesion has been present; the frequency of episodes in recurrent cases; the presence or absence of pain; and the growth of the lesion over time. For multiple or recurrent lesions the presence or history of ulcers on the skin, genital areas, or eyes should be evaluated along with any accompanying systemic symptoms such as fever, arthritis, or other signs of underlying systemic disease. Biopsy may be indicated in many ulcerative lesions of the oral cavity although some are more suitable for clinical diagnosis. Neoplastic ulcerated lesions are notorious in the oral cavity for their ability to mimic benign ulcerative lesions, highlighting the essential nature of biopsy to establish a diagnosis in cases that are not clinically identifiable or do not respond as expected to treatment. Adjunctive tests may be required for final diagnosis of some ulcerated lesions especially autoimmune lesions. Laboratory tests or evaluation to rule out systemic disease may be also required for recurrent or severe ulcerations especially when accompanied by other symptoms. This discussion will describe the clinical and histopathologic characteristics of a variety of ulcerated lesions found in the oral cavity.

Oral blistering - report of two cases of erythema multiforme & literature review.

Erythema multiforme and related disorders comprise a group of mucocutaneous disorders that often compromise the quality of life. The clinical classification of these disorders is variable, thus making definitive diagnosis difficult. Early recognition and prompt management will benefit the patients. This article highlights two such cases of erythema multiforme with detailed literature review on etiopathogenesis, clinical features, and treatment.

Drug induced oral erythema multiforme: A rare and less recognized variant of erythema multiforme.

Oral erythema multiforme (EM) is considered as a third category of EM other than EM minor and major. Patients present with oral and lip ulcerations typical of EM but without any skin target lesions. It has been reported that primary attacks of oral EM is confined to the oral mucosa but the subsequent attacks can produce more severe forms of EM involving the skin. Hence, it is important to identify and distinguish them from other ulcerative disorders involving oral cavity for early management. This article reports two cases of oral EM that presented with oral and lip ulcerations typical of EM without any skin lesions and highlights the importance of early diagnosis and proper management.
