Lichen Planus and Lichenoid Skin Eruptions in Children
Arti Nanda, Kuwait
Lichenoid skin eruptions represent a heterogeneous group of inflammatory disorders characterized by a shared clinical and histopathological pattern of interface dermatitis. Although relatively uncommon in childhood, these conditions pose significant diagnostic and therapeutic challenges because of their diverse etiologies, variable clinical presentations, and overlap with other papulosquamous dermatoses.
This lecture will provide a practical, evidence-based overview of lichen planus and selected lichenoid dermatoses encountered in pediatric practice. The session will begin with a brief overview of the clinical and histopathological features of the lichenoid tissue reaction pattern, followed by discussion of childhood lichen planus, based on personal experience combines with evidence based literature, and current management strategies.
The lecture will also focus on two important acquired lichenoid disorders: lichenoid drug eruptions and lichenoid graft-versus-host disease (GVHD). Early recognition of these entities has become increasingly important for optimizing patient outcomes.
To complete the spectrum of pediatric lichenoid disorders, the session will provide a brief overview of other lichenoid disorders including lichen nitidus, lichen striatus, and others in a tabloid form and key distinguishing points from lichen planus.
Throughout the lecture, practical clinical pearls, illustrative cases, and clinicopathological correlations will be used to facilitate an accurate and systematic approach to diagnosis and management.
By integrating current evidence with real-world clinical experience, this session aims to equip pediatric dermatologists and clinicians caring for children with a practical framework for evaluating and managing lichenoid skin eruptions in everyday practice.
Learning objectives:
- Recognize the clinical spectrum, clinicopathological features, and differential diagnosis of lichen planus and other lichenoid skin eruptions in children.
- Differentiate childhood lichen planus from other lichenoid disorders using key clinical, dermoscopic, and histopathological clues.
- Apply recent evidence-based approach to the investigation and management of pediatric lichenoid disorder.

Vascular anomalies in newborns
Andrea Diociaiuti, Italy
Congenital vascular lesions require a structured diagnostic approach grounded in current international classifications and evidence-based recommendations. According to the International Society for the Study of Vascular Anomalies (ISSVA) classification, vascular anomalies are broadly categorized into vascular tumors and vascular malformations.
Vascular tumors, such as infantile hemangiomas, are characterized by endothelial proliferation, whereas vascular malformations are structural vascular defects present at birth that grow proportionally with the patient. Vascular malformations are further classified into slow-flow lesions (capillary, venous, and lymphatic malformations) and fast-flow lesions (arteriovenous malformations). Accurate classification is essential for guiding appropriate diagnostic work-up and treatment strategies.
Clinical evaluation should include age at presentation, lesion location, growth pattern, and the presence of functional symptoms, such as airway compromise or dysphagia, as well as cosmetic and neurological concerns. Particular attention should be given to syndromic associations, including PHACE syndrome, Klippel–Trénaunay syndrome, and other overgrowth disorders. Doppler ultrasonography represents the first-line imaging modality for superficial lesions and for the assessment of flow characteristics, enabling differentiation between slow-flow and fast-flow anomalies.
When ultrasonographic findings suggest a vascular malformation or when lesions are deep-seated or anatomically complex, further investigation with magnetic resonance imaging (MRI) and/or computed tomography (CT) is indicated.
Digital subtraction angiography (DSA) is reserved for fast-flow malformations, especially arteriovenous malformations, serving both diagnostic and therapeutic planning purposes, particularly before embolization procedures.
Imaging should systematically evaluate lesion extent, involvement of critical structures such as the airway, orbit, and central nervous system, and the presence of multifocal disease. In diagnostically challenging cases, or when clinical and radiological findings are inconclusive, histopathological examination remains the gold standard for definitive diagnosis and therapeutic planning.
Key Learning Objectives:
- Differentiate vascular tumors from vascular malformations according to the ISSVA classification.
- Apply an evidence-based diagnostic approach to congenital vascular lesions, integrating clinical assessment, imaging and digital subtraction angiography when appropriate.
- Identify indications for histopathological evaluation and multidisciplinary management.
