Pediatric molluscum: an update
1Departments of Dermatology and Pediatrics, Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Abstract:
Molluscum contagiosum virus (MCV) is a poxvirus that causes infection in humans that is limited to the cutis and subcutaneous levels of the skin. The virus is transmitted from close associates in settings such as pools, day care, and bathtubs. Pediatric molluscum is common in school-aged children and resolves spontaneously in healthy children. Widespread lesions, complicated by comorbid dermatitis, are expected in children with atopic dermatitis (AD); however, even children without AD can develop dermatitis or signs of inflammation or pruritus. Molluscum is the great mimicker in pediatric dermatology; the morphology of the lesions and overlying rash can make molluscum look polymorphous and similar to other skin illnesses. This article addresses the issue of transmission, course of disease, comorbidities, and therapeutic options, including the gold standard-nonintervention. The decision to intervene is a joint decision among children, parents/guardians, and the practitioner. The first priority should be reduction of symptoms, followed by reduction of spread and then disease remission.
Insights
Molluscum contagiosum virus (MCV) causes common skin infections in children. While often self-resolving, it can mimic other conditions and cause complications, especially in those with atopic dermatitis.
Area of Science:
- Dermatology
- Virology
- Pediatrics
Background:
- Molluscum contagiosum virus (MCV) is a poxvirus infecting the skin's cutis and subcutaneous levels.
- Transmission occurs through close contact in shared environments like pools and daycares.
- Pediatric molluscum is common, typically resolving spontaneously in healthy children but can be widespread and complicated by dermatitis in those with atopic dermatitis (AD).
Purpose of the Study:
- To review the transmission, disease course, and comorbidities of molluscum contagiosum.
- To discuss therapeutic options for molluscum contagiosum, emphasizing non-intervention as the gold standard.
- To highlight the importance of shared decision-making in managing molluscum contagiosum.
Main Methods:
- Literature review on molluscum contagiosum transmission, clinical presentation, and management.
- Analysis of clinical characteristics and diagnostic challenges, particularly its mimicry of other pediatric skin conditions.
- Evaluation of current therapeutic strategies and the rationale for non-intervention.
Main Results:
- MCV infection presents with polymorphous lesions that can mimic various dermatoses.
- Children with atopic dermatitis are prone to widespread lesions and secondary inflammation or pruritus.
- Non-intervention is the primary management strategy, with intervention decisions made jointly by clinicians and families.
Conclusions:
- Molluscum contagiosum requires careful diagnosis due to its varied presentation.
- Management priorities include symptom reduction, limiting spread, and achieving disease remission.
- Shared decision-making is crucial for effective molluscum contagiosum management in children.
