pityriasis rosea

The coronavirus disease 2019 (COVID-19) infection has led to accelerated development and utilization of vaccines to prevent its implications on health. One of these vaccines is a vector-based, Oxford-AstraZeneca Vaccine (AZD1222). Frequently reported side effects are related to host-immune response. While dermatologic manifestation is peculiar in nature and denotes a serious eruption that might defer future vaccination. Herein, we present a case of a medically free 37-year-old female who developed clinical and histological evidence of pityriasis rosea (PR) after administration of a second-dose vaccination of AZD1222...

Pityriasis rosea (PR) is a common inflammatory, erythematous and scaly skin condition that usually affects individuals aged from 20 to 40 years old. The disease often exhibits a self-limiting course up to 6-8 weeks. We report a 25-year-old female patient with a six-month history of red scaly rashes on the trunk and proximal limbs, accompanied by severe pruritus that has been remained ineffective conventional treatments. She was diagnosed as persistent pityriasis rosea. As abrocitinib has been proved to be effective for many inflammatory diseases, therefore in this case, we tried abrocitinib for the patient, and a good result had been achieved...

In the wake of a global COVID-19 pandemic, where innovations in vaccination technology and the speed of development and distribution have been unprecedented, a wide variety of post-vaccination cutaneous reactions have surfaced. However, there has not been a systematic review that investigates pityriasis eruptions and the associated variants following COVID-19 inoculations. A PubMed search using Preferred Reporting Items for Systematic Reviews and Meta-Analyses was performed to find case reports from the earliest record through November 2022...

INTRODUCTION: Psoriasis is an autoimmune papulosquamous disorder characterized by erythematous plaques. There are various subtypes, of which follicular psoriasis (FP) is an underreported entity, presenting as scaly follicular papules. Only a few cases have been reported, with limited dermoscopy findings having been described. This report aims to review the literature and emphasize the role of dermoscopy in the diagnosis of this rare variant. CASE REPORT: A 31-year-old diabetic and obese male presented with symmetrical, itchy, scaly follicular lesions on his axillae, elbows, and knees for 6 months...

INTRODUCTION: Secondary syphilis is well-known for its protean cutaneous manifestations and therefore very easy to be misdiagnosed. AIM: The current study was to observe the frequency of histopathological features characterizing secondary syphilis, and summarize the diseases most likely to be misdiagnosed. MATERIAL AND METHODS: In this study a total of 129 pathological specimens from 114 patients with biopsy-proven secondary syphilis were retrospectively analysed and categorized according to clinicopathologic characteristics...

BACKGROUND: Currently, four vaccines for COVID-19 have been licensed by the European Medi-cines Agency: viral vector-based vaccines (AstraZeneca; AZD1222 and Johnson & Johnson; Ad26.COV2. and 2 mRNA-based vaccines (Pfizer/BioNTech; BNT162b2 and Moderna; mRNA-1273). Since their approval, several cutaneous reactions related to vaccination have been reported in the literature. Among these, viral reactivations are one of the most frequent. OBJECTIVES: The aim of this manuscript was to investigate current literature regarding viral reactivations following COVID-19 vaccination, focusing the attention on Pityriasis Rosea, Herpes Zoster and Herpes Simplex...

BACKGROUND: Plaque psoriasis is relatively straightforward to identify. When diagnostic concerns arise in atypical cases, a biopsy is needed. It is widely accepted that the Munro microabscess and the spongiform pustule of Kogoj are diagnostic pathological features. However, the diagnostic dilemma is likely to arise in cases without these specific pathological changes and typical clinical features. This study aimed to investigate clinical and pathological clues in distinguishing atypical plaque psoriasis from its mimics...

Pityriasis rosea (PR), a benign and self-limiting skin disorder, typically manifests as a single initial lesion known as the herald patch. The herald patch is commonly followed by the development of secondary erythematous papules and plaques, aligning with Langer's lines to form a specific distribution pattern, resembling a Christmas tree on the back and a V-shaped pattern on the upper chest. Therefore, diagnosing PR may not be difficult based on its typical clinical presentation. In contrast, cases of atypical PR presentation have been reported, encompassing several differential diagnoses...

Skin diseases in Trinidad and Tobago, demonstating differences in Hospital vs Primary Care Dermatology Clinics, paediatric age groups and use of laboratory services. This figure illustrates, (a) combined percentage in range of skin diseases from all sites, n  = 1309. Other diseases included CTD (connective tissue disease), papular urticaria, prurigo, rosacea and pityriasis rosea. (b) Paediatric dermatology conditions seen in one PCHF (primary care health facility) versus hospital clinics. (c) Comparison of waiting times, source of referrals and use of pathology in all PCHF versus hospital clinics...

INTRODUCTION: Mucocutaneous complications or adverse events due to SARS-CoV-2 infection or vaccination have been well delineated in the literature, respectively. Most eruptions are considered mild and self-limiting; however, for the atypical cases with a tentative clinical diagnosis, performing a biopsy and histopathological assessment is pivotal to confirm the diagnosis and subsequently prescribe a more tailored treatment. Despite the diverse reporting of such incidents globally, most studies restrict the rate of biopsied cases to less than 15%...

BACKGROUND: Preliminary data support the possible use of ultraviolet-induced fluorescence (UVF) dermoscopy in general dermatology, yet no accuracy analysis has been performed so far. OBJECTIVE: To evaluate diagnostic accuracy of UVF dermoscopy in clinically similar non-neoplastic conditions as compared to polarized light-based dermoscopy. METHODS: Patients with dermatoses potentially showing UV-induced findings were considered; cases were grouped according to clinical patterns and controls were also included...

Subacute cutaneous lupus erythematosus (SCLE) is a condition that might pose a diagnostic challenge. The aim of this study was to assess the usefulness of videodermoscopy in the differentiation of SCLE from other erythematous-desquamative dermatoses. Consecutive patients with SCLE ( n = 27), psoriasis ( n = 36), nummular eczema ( n = 30), mycosis fungoides ( n = 26), and pityriasis rosea ( n = 20) referred to our Department of Dermatology were recruited for this study. A representative lesion was visualized using a Canfield D200EVO Videodermatoscope (Canfield Scientific GmbH, Bielefeld, Germany) and evaluated for the following parameters: vessels (morphology and distribution), scales (color and distribution), follicular findings, colors and morphologies, and presence of specific clues...

To mitigate the impact of the COVID-19 pandemic, several vaccines have been developed and administered to the public since 2021. A spectrum of cutaneous reactions has been reported among some of the vaccinated individuals. In this case series, we describe three cases of pityriasis rosea and pityriasis rosea-like eruption that manifested after COVID-19 vaccinations, which might suggest the vaccines as a possible trigger.

COVID-19 pandemic completely changed every aspect of human life. Several measures were adopted to limit the spreading of the infection. Among these, vaccination was the main one. Globally, vaccination campaign was a success, showing to be efficient in controlling and preventing the SARS-Cov2 infection, reducing the risk of disease progression, hospitalization, and mortality. However, with the increasing number of vaccines administered, several cutaneous reactions were described, making dermatologists key players in their recognition and treatment...

PURPOSE: The study aimed to describe the dermoscopic features of pityriasis rosea among patients attending the skin clinic at Mbarara Regional Referral Hospital. PATIENTS AND METHODS: A hospital-based cross-sectional descriptive study conducted for a 6-month period in the skin clinic of MRRH in Southwestern Uganda. Data were collected from consecutively recruited patients using structured questionnaires. Patients with a clinical diagnosis of pityriasis rosea were examined using a dermoscope and subsequently sent for KOH and TPHA tests to rule out fungal skin infection and secondary syphilis, respectively, and then received routine care at the skin clinic...
