RESUMO
Eczema herpeticum (EH) is a severe and potentially life-threatening viral infection occurring in individuals with preexisting eczema or atopic dermatitis. It is primarily caused by the herpes simplex virus, presenting as painful vesicular eruptions on the skin. On the other hand, acute localized exanthematous pustulosis (ALEP) is a rare variant of acute generalized exanthematous pustulosis (AGEP), characterized by the sudden onset of localized, nonfollicular pustules on an erythematous base. It is often triggered by recent medication administration, and its clinical presentation mimics AGEP, although ALEP exhibits a confined distribution of pustules. Prompt diagnosis and identification of the offending agent are crucial for effective management. Both are distinct cutaneous manifestations that rarely occur concurrently, presenting unique diagnostic and therapeutic challenges. We present the first documented case of coexisting ALEP and EH in a 32-year-old male with a history of atopic dermatitis. The patient was admitted with features suggestive of EH, including vesicular lesions over the face, along with a positive Methicillin-resistant Staphylococcus aureus (MRSA) swab. Treatment with ceftaroline initially initiated resulted in the development of localized pustules, indicative of ALEP. Transition to linezolid led to the complete resolution of both conditions, marking a compelling recovery. The distinctive interplay between EH, ALEP, and AGEP presents a novel challenge, emphasizing the need for nuanced clinical assessment and tailored therapeutic strategies. This case offers crucial insights into the intricate relationship between medication-induced dermatological conditions and underlying cutaneous vulnerabilities. This unprecedented case highlights the rarity and complex management nuances associated with the simultaneous occurrence of ALEP and EH. The successful resolution following medication adjustments underscores the need for flexibility and comprehensive evaluation in addressing such intricate dermatological scenarios, providing valuable insights into potential synergies between distinct cutaneous conditions.
RESUMO
BACKGROUND: Eczema herpeticum is a rapidly progressing skin complication related to the herpes simplex virus, particularly in individuals with compromised immune systems or atopic dermatitis. Eczema herpeticum is characterized by cutaneous pain, scaling, and the presence of vesicular lesions, often accompanied by secondary infection. Dissemination of the infection can lead to severe morbidity and mortality in patients without appropriate antiviral and antibiotic therapy. CASE REPORT: We presented a case of ankylosing spondylitis in a relatively young patient who did not receive immunosuppressive therapy and had no history of Human Immunodeficiency Virus, herpes zoster infection or atopic dermatitis. The patient's symptoms improved following a course of antiviral and antibiotic treatments. INTRODUCTION: The incidence of eczema herpeticum has been on the rise in recent decades, primarily due to an increased number of individuals with compromised immune systems. This increase can be attributed to various factors, including the higher prevalence of Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome, the more extensive use of immunosuppressive therapy, and what seems to be a growing incidence of atopic dermatitis.[1] This disease can be initially mistaken for Stevens-Johnson syndrome because of the rapid advancement of skin lesions, however, the atypical target lesions, flaccid bullae and prominent mucosal involvement found in Stevens-Johnson syndrome are absent in cases of eczema herpeticum. Other differential diagnoses include impetigo, disseminated herpes zoster, acute generalized exanthematous pustulosis, dermatitis herpetiformis.

Atopic dermatitis (AD) characterized by pruritus and eczematous lesions makes individuals susceptible to various viral and bacterial infections. Eczema herpeticum (EH), also known as Kaposi's varicelliform eruption, is a severe herpes simplex virus infection that can be observed in individuals with AD. EH manifests with monomorphic vesicles and "punched-out" erosions accompanied by hemorrhagic crusts, primarily affecting eczematous areas. Misdiagnosis, often as impetigo, can lead to severe complications and even death. Timely diagnosis and treatment with acyclovir are crucial to avert these outcomes. Here we present a case of a 19-year-old male with AD who presented with a monomorphic vesicular rash.
RESUMO
Introduction: Kaposi's varicelliform eruption (KVE), also known as eczema herpeticum or eczema vaccinatum, is an acute dermatosis that affects patients with chronic dermatopathies. The diagnosis is primarily clinical and is characterised by the presence of a vesicular exanthema on physical examination. The exanthema subsequently evolves into crusted lesions with typical circular ulcerations in 'punched-out' areas on the skin affected by the underlying dermatopathy. Case description: We present the case of a 6-year-old patient who presented to the Paediatric Emergency department with skin lesions consistent with eczema herpeticum. The patient's management was initially outpatient; however, due to the slow progression of the condition, hospitalisation and intravenous antiviral treatment were initiated. Discussion: KVE affects patients with chronic dermatoses, especially atopic dermatitis. It is important to know the clinical presentation for an early suspicion. KVE is a medical emergency that requires prompt diagnosis and treatment. It can progress to secondary viraemia, which can be fatal in up to 10% of immunocompetent individuals and up to 50% of immunocompromised individuals. It is important to be aware of this condition and to start early treatment with antivirals, especially given the high prevalence of atopic dermatitis in our population. This condition is one of the most serious complications that can occur in these patients. LEARNING POINTS: To facilitate early suspicion and diagnosis, disseminate information about eczema vaccinatum.Emphasise the importance of initiating antiviral treatment early to prevent potential complications of eczema herpeticum.If left untreated, Kaposi's varicelliform eruption can result in up to a 10% mortality rate in immunocompetent individuals and a 50% mortality rate in those who are immunocompromised.
RESUMO
This chapter will describe infectious complications of atopic dermatitis, including bacterial, viral, and fungal infections and the evolving understanding of the relationship between atopic dermatitis and infectious disease. The underlying immunological dysregulation and poor skin barrier function associated with atopic dermatitis not only increase the likelihood of infectious complications but also lend atopic dermatitis skin vulnerable to flares induced by environmental triggers. Thus, this chapter will also highlight the impact of common external environmental agents on precipitating flares of disease. Lastly, this chapter will discuss complications that can arise from treatments and the association of atopic dermatitis with more serious conditions such as lymphoma.

Eczema herpeticum (EH) is a cutaneous manifestation of disseminated herpes simplex virus, commonly observed in patients with active eczema. The condition often presents with systemic symptoms, including fever and fatigue, alongside vesiculopustular skin lesions. This case report describes a 19-year-old male with active eczema who was misdiagnosed with facial cellulitis in the emergency and inpatient setting in a community tertiary hospital. With worsening rash and development of ocular symptoms, the diagnosis was reconsidered to be more consistent with EH with herpetic keratitis, which improved with antiviral treatment. This report shows the significance of maintaining a high index of suspicion for EH in patients with eczema and the potential consequences of misdiagnosis and delay in treatment. It aims to enhance clinician awareness of EH and promote a broader differential for unusual presentations of common dermatological and ophthalmologic conditions, especially when caring for patients with limited access to specialist evaluation.
RESUMO
Atopic dermatitis (AD) has become a global health concern due to an increase in its frequency over the past few decades. This illness not only reduces the quality of life but also imposes a considerable financial burden due to the increased risk of skin infections. This case report explores the presentation of a four-month-old male infant with a personal history of atopic dermatitis that developed yellow scaly lesions on the scalp, which were assumed to be cradle cap. However, there was a clinical worsening of the cutaneous lesions, with the appearance of vesicles, so he was referred to the Pediatric Emergency Room after an urgent dermatology appointment. A blood test was performed, which revealed severe eosinophilia and a slightly increased total IgE. Considering the patient's past medical record of atopic dermatitis and the observable characteristics of the skin rash, there was a strong suspicion of eczema herpeticum (EH). Consequently, intravenous acyclovir treatment was initiated, along with an antibiotic, as there were concerns about a potential secondary infection. He was followed up with a pediatric and dermatology appointment, with a resolution of skin lesions after six weeks. EH is a rare clinical entity, usually caused by herpes simplex virus (HSV) types 1 and 2. It is a clinical entity that, while being uncommon, is one of the few dermatological emergencies responsible for a high morbidity rate, associated with the systemic spread of the viral infection.
RESUMO
BACKGROUND: Kaposi Varicelliform Eruptions (KVE), also known as eczema herpeticum, is a rare and potentially life-threatening dermatological condition primarily attributed to herpes simplex virus (HSV) infection, with less frequent involvement of Coxsackie A16, vaccinia, Varicella Zoster, and smallpox viruses. Typically associated with pre-existing skin diseases, especially atopic dermatitis, KVE predominantly affects children but can manifest in healthy adults. Characterized by painful clusters of vesicles and sores on the skin and mucous membranes, it often masquerades as other dermatological disorders. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used for pain relief and inflammation, though their potential role as KVE triggers remains uncertain. CASE REPORT: Here, we present a case of an 18-year-old female with KVE attributed to Varicella Zoster virus (VZV) and successfully treated with oral acyclovir within a week, underscoring the significance of early recognition and intervention. KVE can manifest with systemic symptoms like fever, fatigue, and lymphadenopathy and may involve multiple organ systems, necessitating possible antibiotic use for complications. CONCLUSION: This case underscores the importance of prompt KVE identification and consideration of antiviral therapy to enhance patient outcomes. Further research is warranted to elucidate predisposing factors for this rare condition.

La erupción variceliforme de Kaposi es una infección cutánea diseminada, causada en la mayor parte de los casos por el virus Herpes simple tipo 1. Se suele presentar en pacientes con alteraciones preexistentes de la barrera cutánea, especialmente en niños con dermatitis atópica. Se comunica el caso de un paciente de 84 años, quien negaba enfermedades cutáneas previas, que consultó por lesiones dolorosas y pruriginosas, en la piel del tórax y el abdomen, de 3 semanas de evolución. Con sospecha de una enfermedad infecciosa viral, bacteriana, ampollar o neutrofílica, se realizó inmunofluorescencia directa para herpes, cultivo y biopsia de piel para estudio histológico. La inmunofluorescencia fue positiva para Herpes simple tipo 1 y el estudio histopatológico mostró cambios compatibles con infección herpética y enfermedad de Darier. La enfermedad de Darier es una genodermatosis infrecuente que se suele manifestar en la adolescencia. Si bien su diagnóstico en la ancianidad es excepcional, este caso ilustra que se debe considerar en todos los pacientes que presenten erupción variceliforme. (AU)
Kaposi's varicelliform rash is a disseminated cutaneous infection, caused by Herpes virus 1. It usually presents in patients with pre-existing skin barrier disorders, especially in children with atopic dermatitis. We report the case of an 84-year-old patient, who reported having no previous skin diseases, who consulted for painful, itchy, 3-week-old skin lesions. As we suspected viral, bacterial, bullous or neutrophilic disease, direct immunofluorescence, culture, and skin biopsy for histological study were performed. Immunofluorescence was positive for Herpes simplex type 1 and the histopathological study showed changes compatible with herpetic infection and Darier's disease. Darier's disease is a rare genodermatosis that usually manifests in adolescence. Although its diagnosis in old age is anecdotal, it should be considered in patients with a varicelliform rash. (AU)

Eczema herpeticum is an extensive vesicular eruption caused by cutaneous dissemination of herpes simplex virus in patients who have underlying skin conditions or epidermal barrier disruption. Herpes simplex virus type 1 (HSV 1) is the most common etiology. This is the first report in Chile of a case of eczema herpeticum caused by HSV 2 in a patient with Darier' s disease, We review the literature and emphasize the use of sensitive and specific assays as real time polimerase chain reaction, that allow to initiate timely the correct treatment.
El eccema herpético es una erupción vesicular extensa causada por la diseminación cutánea del virus herpes simplex, en pacientes con trastornos cutáneos previos o daño de la barrera epidérmica. La etiología más frecuente es virus herpes simplex tipo 1 (VHS 1), aunque se han reportado casos de virus herpes simplex tipo 2 (VHS 2). Presentamos el primer reporte en Chile de eccema herpético por VHS 2 en un paciente con enfermedad de Darier. Realizamos una revisión de la literatura médica y destacamos la importancia del uso de técnicas sensibles y específicas como la reacción de polimerasa en cadena (RPC) en tiempo real, que posibilitan el inicio precoz de la terapéutica correcta.

O objetivo deste relato de caso foi apresentar uma paciente com dermatite atópica (DA) e que no primeiro ano de vida desenvolveu quadro infeccioso grave com eczema difuso em face pescoço e tórax, acompanhado de celulite periorbitária bilateral, febre alta, gemência, hipoatividade e acentuado comprometimento do estado geral. Pele xerótica com lesões vesículares, umbilicadas e com secreção purulenta. O isolamento de Staphy/occus aureus em hemocultura confirmou a suspeita de septicemia e o tratamento antimicrobiano efetivo (Ceftriaxona e Oxacilina) permitiu o seu controle e evidenciou a presença de Eczema herpeticum em face. O tratamento com Aciclovir intra-venoso e cuidados locais possibilitaram o seu controle. A infecção viral funcionou como porta de entrada para o S.aureus causando a septicemia, pouco comum em DA não complicada.
The aim of this report is to relate a one year-old female patient with atopic dermatitis (AD) that developed a severe infectious clinical picture associated with diffuse eczema in face, neck and thorax, bilateral per orbital cellulite, elevated fever, groaning, underactivity, and accentuated commitment of general condition. Pustule umbilicated vesicles over a xerotic skin were observed. Hemoculture reveals Growing of Staphy/occus aureus in hemoculture confirmed septicemia diagnose and specific antibiotic therapy (Ceftriaxona e Oxacilina) allowed its control and put in evidencethe presence of facial Herpeticum eczema. The intravenous treatment with Acyclovir associated with local care enable its control. Virus infection was the S. aureus entrance door causing septicemia, uncommon in no complicated DA patients.
