Acute generalized exanthematous pustulosis complicated by cutaneous small vessel vasculitis: A case report and literature review

Acute generalized exanthematous pustulosis (AGEP) is a rare skin eruption characterized by widespread erythematous lesions covered with numerous pustules. Leukocytoclastic vasculitis is now considered an uncommon but possible histopathological feature within the clinical and pathological spectrum of AGEP. Our report describes a rare case of AGEP overlapping with cutaneous small vessel vasculitis, a condition that has only been reported once in the literature.

Evidence of Mpox Virus Infection Among Persons Without Characteristic Lesions or Rash Presenting for First Dose of JYNNEOS Vaccine-District of Columbia, August 2022

We assessed mpox virus prevalence in blood, pharyngeal, and rectal specimens among persons without characteristic rash presenting for JYNNEOS vaccine. Our data indicate that the utility of risk-based screening for mpox in persons without skin lesions or rash via pharyngeal swabs, rectal swabs, and/or blood is likely limited.

Blistering rash in a child

A 5-year-old child was brought to the dermatology department with a blistering rash on the lower limbs. Indirect and direct immunofluorescence, in conjunction with haematoxylin and eosin showed a rare blistering disorder.

Generalized maculopapular rash and fever

Was this a case of the "great masquerader"? Or was it something else?

Recurrent reactive infectious mucocutaneous eruption in a male adult patient associated with Mycoplasma pneumoniae, SARS-CoV-2 and rhinovirus

We present a case of a man in his early 30s who developed four episodes of reactive infectious mucocutaneous eruption (RIME), in association with different infectious pathogens.RIME is a recently implemented term to describe mucocutaneous eruptions associated with respiratory pathogens. These eruptions are characterised by predominant mucosal involvement of two or more mucous membranes and limited cutaneous involvement. The disease course and prognosis are mostly favourable, especially in recurrent episodes of RIME in the same patient. In recurrent episodes of RIME, Mycoplasma pneumoniae is often identified as the infectious trigger in the first episode.

Ocular involvement in Mycoplasma induced rash and mucositis: A systematic review of the literature

Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a relatively newly identified clinical entity which is characterized by mucocutaneous manifestations in the setting of Mycoplasma infection. Though a clinically distinct disease, MIRM exists on a diagnostic continuum with entities including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and the recently described reactive infectious mucocutaneous eruption (RIME). In this systematic review, we discuss published findings on the epidemiology, clinical manifestations, diagnosis, and management of MIRM, with an emphasis on ocular disease. Lastly, we discuss some of the most recent developments and challenges in characterizing MIRM with respect to the related diagnosis of RIME.

How to differentiate skin rash in covid, mononucleosis, chickenpox, sixth disease and measles

PURPOSE OF REVIEW

Skin rashes seen during COVID-19 usually feature maculopapular or vesicular morphology, thus mimicking cutaneous eruptions occurring in other common infectious dermatoses, such as mononucleosis, chickenpox, sixth disease and measles, with possible diagnostic mistakes. In this review article, we sought to provide a practical overview about clinical appearance of skin rashes related to SARS-CoV-2 infection.

RECENT FINDINGS

The study summarizes literature evidence on clinical patterns of COVID-19-associated maculopapular or vesicular rash, with a particular emphasis on the principal points of differentiation with possible mimickers.

SUMMARY

Several differences do exist between rashes due to SARS-CoV-2 infection and other viral eruptions, mainly including lesions morphology, spreading pattern, symptoms and mucosal involvement. The increase of awareness of such features among clinicians may help promptly recognize COVID-19-related exanthemas in order to take proper action to manage the infection.
