BACKGROUND: The emerging chikungunya virus (CHIKV), is an arbovirus causing intense outbreaks in North America. The situation in Mexico is alarming, and CHIKV threatens to spread further throughout North America. Clinical and biological features of CHIKF outbreaks in Mexico have not been well described; thus, we conducted a cross sectional study of a CHIKV outbreak in Chiapas, Southern Mexico to further characterize these features. METHODOLOGY/PRINCIPAL FINDINGS: We collected blood samples from patients suspected of having chikungunya fever (CHIKF) who presented to Clinical Hospital ISSSTE Dr...

Enteroviruses are the leading cause of exanthems in children, especially during summer and autumn. Enterovirus infections may occur in epidemics or small outbreaks. A 30-year-old woman presented with a three-day history of an erythematous maculopapular skin rash with petechiae localized exclusively under the nipple of the right breast. The skin eruption was associated with an erythematous-petechial enanthem. The patient complained of low-grade fever, headache, asthenia, sore throat and arthromyalgias. IgM (1:128) and IgG (1:640) antibodies against Coxsackievirus A4 were detected by the virus neutralization test...

REVIEW
M Mockenhaupt
Among severe drug reactions in children, besides Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), a specific form of hypersensitivity syndrome which is nowadays known as "drug reaction with eosinophilia and systemic symptoms" (DRESS) has to be mentioned. Whereas SJS/TEN is considered one reaction entity of different severity, DRESS has to be distinguished from SJS/TEN but also from other severe exanthems due to multiorgan involvement. Although SJS/TEN is generally referred to as a drug reaction, only about 75% of all cases are actually caused by medications and in children it is only about 50%...

BACKGROUND: Viral infections and drug reactions are commonest causes of exanthem in clinical practice. Clinically, it may pose a diagnostic challenge due to overlapping features. Hematological, in vitro and drug provocation tests are either not reliable or practical. METHODS: This was a descriptive, prospective study to assess and compare histopathological features of maculopapular viral and drug exanthem. Subjects fulfilling case definition of exanthems were included...

BACKGROUND: Primary Human herpesvirus-7 (HHV-7) infection usually occurs during childhood and causes several clinical manifestations: mainly exanthem subitum (roseola infantum), followed by a lifelong latent state with possible reactivation in case of immunodeficiency. Nevertheless, some considerably different approaches exist regarding the natural history of HHV-7 and the possible consequences of HHV-7 infection in immunocompetent adults. In particular, little is known about its pathogenic role in central nervous system (CNS) disease in nonimmunosuppressed adults...

REVIEW
Abraham M Korman, Ali Alikhan, Benjamin H Kaffenberger
Although classic viral exanthems of childhood are well described, they are rarely differentiated in adults. Laboratory techniques for viral identification have advanced without substantial literature to suggest how a dermatologist ought to conduct a cost-effective and diagnostic viral panel. Certain clinical features such as petechiae, vesicles, and dusky macular or morbilliform exanthems point strongly toward a viral exanthem. Differentiation of drug and viral causes of morbilliform eruptions has proven difficult...

Fever is a symptom that often accompanies skin eruptions, especially in children. It can be a sign of an infectious condition presenting with exanthems or it may precede an exanthematous eruption. Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe reactions affecting skin and mucosa with blisters and erosions. High fever occurs in these conditions, frequently before the skin and/or mucosa is affected.

Pityriasis rosea (PR) is an acute self-limited exanthem characterized by oval erythematous patches with scale and may be difficult to differentiate from secondary syphilis. A rapid plasma reagin (RPR) test can be used to rule in secondary syphilis with high sensitivity and specificity. A retrospective study was performed on patients at Weill Cornell Medicine, who were diagnosed with PR from 2000 to 2016 and also received RPR testing at the time of diagnosis. The objective was to assess the frequency of secondary syphilis when the initial clinical impression was PR...

Multiple drug hypersensitivity (MDH) is a syndrome that develops as a consequence of massive T-cell stimulations and is characterized by long-lasting drug hypersensitivity reactions (DHR) to different drugs. The initial symptoms are mostly severe exanthems or drug rash with eosinophilia and systemic symptoms (DRESS). Subsequent symptoms due to another drug often appear in the following weeks, overlapping with the first DHR, or months to years later after resolution of the initial presentation. The second DHR includes exanthema, erythroderma, DRESS, Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), hepatitis, and agranulocytosis...

REVIEW
R Fölster-Holst, V Zawar, A Chuh
Paraviral exanthems are distinct skin diseases due to infections with different viruses. Although no virus has been identified so far in some exanthems, the main age of manifestation, the clinical course of the exanthem, and the extracutaneous symptoms are suggestive for a viral genesis. While many viral infections are a direct result of the infection, paraviral exanthems reflect the response of the immune system to the infectious pathogens. Viruses cannot be identified in the skin. Typical paraviral exanthems include Gianotti-Crosti syndrome, pityriasis rosea, pityriasis lichenoides, papular-purpuric gloves and sock syndrome, and asymmetrical periflexural exanthema...

REVIEW
Mark R Wick
Some cutaneous inflammatory disorders are typified by a predominant or exclusive localization in the dermis. They can be further subdivided by the principal cell types into lymphocytic, neutrophilic, and eosinophilic infiltrates, and mixtures of them are also seen in a proportion of cases. This review considers such conditions. Included among the lymphoid lesions are viral exanthems, pigmented purpuras, gyrate erythemas, polymorphous light eruption, lupus tumidus, and cutaneous lymphoid hyperplasia. Neutrophilic infiltrates are represented by infections, Sweet syndrome, pyoderma gangrenosum, and hidradenitis suppurativa, as well as a group of so-called "autoinflammatory" dermatitides comprising polymorphonuclear leukocytes...

We report the diagnostic and therapeutic challenges in an unusually fulminant presentation of measles, presenting as severe necrotizing bronchiolitis with secondary hemophagocytic lymphohistiocytosis (HLH) in the absence of classical clinical features in an immunocompromised host on maintenance chemotherapy. Our patient had presented with features of a viral pneumonitis without the classical exanthem, in combination with HLH. Although rhinovirus-induced HLH was highly unusual, the positive rhinovirus swab result had distracted us from the eventual diagnosis...
