Many clinical and laboratory-based studies have been reported for skin rashes which may be due to viral infections, namely pityriasis rosea (PR), Gianotti-Crosti syndrome (GCS), asymmetric periflexural exanthem/unilateral laterothoracic exanthem (APE/ULE), papular-purpuric gloves and socks syndrome (PPGSS), and eruptive pseudo-angiomatosis (EP). Eruptive hypomelanosis (EH) is a newly discovered paraviral rash. Novel tools are now available to investigate the epidemiology of these rashes. Read More

We report the case of a 4-year-old boy who presented with a transient extensive eczematous eruption on the left side of his trunk and extremities, with clear demarcation in the midline. The eruption started to resolve without any sequelae in 4 weeks. The history and clinical findings suggest that this transient eruption could have been either a case of unilateral blaschkitis in childhood or asymmetric periflexural exanthem. Read More

Asymmetric periflexural exanthema of childhood is a benign, self-limiting disease of unknown origin. Patients generally present a few weeks after a viral-like prodrome with erythematous macules and papules within flexural spaces followed by centrifugal spread. Treatment focuses on alleviating symptoms of pruritus. Read More

Asymmetric periflexural exanthem (APE) is a distinctive exanthem, probably viral in origin. It is largely a disease of childhood and is uncommon in adults. We report an adult man presenting with the typical clinical findings of APE. Read More

Viral exanthems are a common problem in tropical regions, particularly affecting children. Most exanthems are transient and harmless, but some are potentially very dangerous. Pregnant women and malnourished or immunocompromised infants carry the greatest risk of adverse outcome. Read More

Our objective was to study possible etiologic factors of asymmetric periflexural exanthem of childhood (APEC) among a large panel of microbiologic agents not yet investigated. To do so, we designed a prospective case-control study using throat, stool, blood, and skin samples, and enlisted 37 children with APEC and 37 age-matched controls without eruption seen consecutively from February 1995 to April 1996 from a mixed referral center and community-based population. No interventions were done. Read More

Asymmetric peri-flexural exanthem of childhood is a "new" disease, which has never been reported by Danish authors. It is characterized by an asymmetric maculopapular exanthem in early childhood. The exanthem is initially unilateral and localised close to the axilla, but it spreads centrifugally during the first week, becomes more widespread and resolves spontaneously within four to six weeks.

Objective: To assess the clinical, pathologic, and epidemiologic features of asymmetric periflexural exanthem of childhood (APEC), a clinically distinctive eruption, especially its link with pityriasis rosea and pattern of transmission.

Design: A prospective case series, including an analysis of epidemiologic triggering factors and mode of transmission. Pathologic study, including immunohistochemistry of the inflammatory infiltrate. Read More

Childhood exanthems are a common cause of skin disease in children. Several new aspects of exanthems are reviewed. Two conditions, unilateral laterothoracic exanthem and asymmetric periflexural exanthem, may be variations of the same disease and could potentially represent a cutaneous reaction to several infectious agents.

We report on an asymmetric maculopapular exanthem of early childhood. One hundred eighty seven patients (111 girls, 76 boys) were examined over a four-year period, mainly in winter and spring. The first skin lesions appeared on the trunk or in the large flexures of the limbs. Read More

A newly described exanthem of infancy consists of an eczematous or scarlatiniform eruption that starts initially from one axillary fold and spreads unilaterally and centrifugally on the trunk and the proximal part of the upper limb. Minor lesions are infrequently present on the contralateral side. The rash may be slightly pruritic and sometimes associated with a moderate regional lymphadenopathy. Read More
