Pityriasis rosea-like rash after COVID-19 vaccination with Oxford-AstraZeneca: a possible trigger?

Scholars around the world have dedicated themselves to developing an effective vaccine against SARS-CoV-2. However, vaccines have produced adverse effects in some patients. We report the case of a 44-year-old man who developed a pruritic papulosquamous rash on the trunk with a characteristic pattern known as Christmas tree after receiving the first dose of the Oxford-AstraZeneca COVID-19 vaccine, similar to pityriasis rosea (PR). He had no previous symptoms of viral infection and tested negative for neutralizing antibodies (enzyme immunoassay) against COVID-19. There are few reports in the literature about the relationship between the onset of cutaneous adverse reactions and the Oxford-AstraZeneca vaccine, therefore, the dissemination of this case is of paramount importance.

Pitiriasis rosada en el embarazo: reporte de caso / Pityriasis rosea in pregnancy: case report

RESUMEN A pesar de que la Pitiriasis Rosada se considera una condición cutánea benigna, en el marco del embarazo, hay estudios que relacionan la aparición de esta patología con complicaciones asociadas en el feto. Metodología: Se realiza un reporte de caso, prospectivo, a una mujer de 36 años chilena que presentó esta patología durante la semana 12 de gestación. El objetivo fue describir, la evolución y control y contrastar su evolución con la evidencia científica actual sobre esta temática. Resultados: Paciente presenta placas eritematodescamativas concordantes con diagnóstico de pitiriasis rosada (superficie afectada menos al 50% de su cuerpo), sin presentar enantema, ni síntomas sistémicos. Tuvo un recién nacido sano a las 38 semanas de gestación, sin presentar ningún efecto adverso de los que relaciona la literatura analizada. Conclusiones: Distintos estudios han estudiado los posibles efectos adversos en el feto en madres que han presentado Pitiriasis Rosada en el embarazo, sin embargo, en este reporte de caso no se presentaron complicaciones asociadas. Faltan estudios realizados en mayor cantidad de pacientes.

ABSTRACT Although Pityriasis Rosea is considered a benign cutaneous condition, in the context of pregnancy, there are studies that relate the appearance of this pathology with associated complications in the fetus. Methodology: A prospective case report was made to a 36-year-old Chilean woman who presented this pathology during the twelve weeks of pregnancy. The objective was to describe, the evolution and control and to contrast its evolution with the current scientific evidence on this subject. Results: Patient presents concordant erythematous-desquamative plaques with diagnosis of Pityriasis Rosea (surface affected less than 50% of his body), without presenting enanthem, nor systemic symptoms. Had a healthy newborn at 38 weeks of gestation, without presenting any adverse effect related to the analyzed literature. Conclusions: Different studies have studied the possible adverse effects on the fetus in mothers who have presented pityriasis rosea in pregnancy, however in this case report there were no associated complications. Missing studies in a greater number of patients.

Clinical study of a typical Pityriasis rosea in patients attending the department of dermatology and venereology at Rizgary Teaching Hospital in Erbil city

The aim of this study was to measure the rate of a typical cases of pityriasis rosea among dermatological visit and to outline the various clinical presentations of a typical pityriasis rosea disease. This descriptive study was conducted for a period extended from October 2007 through June 2008. 88 patients who diagnosed to have pityriasis rosea were enrolled in this study. The diagnosis was based on history and clinical examination; questionnaire was designed to provide relative data and all patients' data were recorded at time of diagnosis. Investigations in certain cases were done to aid in the diagnosis. A typical pityriasis rosea was found in 38.5% patients. Absence of herald patch in 17% of patients, papular rosea in 8%, inverse pityriasis rosea in 6.8%, localized pityriasis rosea in 4.5%, unilateral/inverse in 1.1% and urticarial in 1.1% of patients A typical pityriasis rosea is not uncommon and different forms of a typical pityriasis rosea exist. Investigations are sometimes needed to confirm the diagnosis

Pitiríase rósea: estudo clínico-terapêutico e apresentação de aspectos clínicos atípicos / Pityriasis rosea: clinical-therapeutic study and atypical clinical aspects presentation

A pitiríase rósea (PR) é uma dermatose inflamatória aguda, autolimitada, caracterizada por lesões eritematodescamativas. É uma doença relativamente comum, apesar da sua etiologia ainda não ter sido identificada. Tem distribuição mundial, acometendo todas as raças e qualquer faixa etária, particularmente adultos jovens. O diagnóstico dos casos típicos é simples e essencialmente baseado nos aspectos clínicos. No entanto, formas atípicas de PR podem representar um desafio ao diagnóstico

Pityriasis rosea--an update.

Recent controversies on the etiology, diagnosis and treatment have led to increased interest in pityriasis rosea (PR). We review these aspects of the disease. PR is universal. The incidence is around 0.68 per 100 dermatological patients, or 172.2 per 100,000 person-years. The prevalence in people aged between 10 and 29 years is 0.6%. The male to female ratio is around 1:1.43. Evidence on seasonal variation is conflicting, but there is no evidence that the incidence is dependent on mean air temperature, mean total rainfall, or mean relative humidity. Spatial-temporal and temporal clustering of cases of PR has been reported. The association of PR with human herpesvirus-7 infection is still controversial. Owing to the extreme high sensitivities of sequence-based detection methods such as polymerase chain reaction, novel criteria should be applied to evaluate the evidence. There is no evidence that PR is associated with other viral or bacterial infections. The role of autoimmunity in PR warrants further investigations. Many patients with PR have one or more atypical features. Application of validated diagnostic criteria may be helpful for atypical cases. The efficacy of macrolides, including erythromycin, in PR is still under evaluation. There is no evidence that antiviral agents are effective. The efficacies of ultraviolet radiotherapy and systemic corticosteroids are not well established. In managing a patient with PR, we should concentrate more on how the eruption is affecting the quality of life, i.e. the illness, rather than the extent and severity of the eruption, i.e. the disease.

Pityriasis rosea-like eruptions due to mustard oil application.

A young man employed in a construction company, presented with cutaneous lesions clinically simulating pityriasis rosea. Satisfactory and complete response to corticosteroids and antihistamines was followed by recurrence. Multiple recurrences within a short span of time arose a suspicion of alternative diagnosis. Site visit helped us to rule out occupational contact dermatitis. Further history taking revealed that he was recently using mustard oil for body massage. Subsequent patch testing confirmed contact hypersensitivity to mustard oil. Avoidance of the contact with mustard oil arrested appearance of further skin lesions. We stress the importance of taking a good history in clinical practice in disclosing a possible contactant.
