Nevi - when to refer.

Curr Opin Pediatr

August 2024

Article Synopsis
  • The chapter focuses on helping pediatricians differentiate between benign and high-risk congenital melanocytic nevi (CMN) and acquired nevi in children, emphasizing the importance of appropriate referrals and management.
  • Recent findings indicate variability in CMN presentations and stress the need for a team-based approach to improve patient outcomes.
  • The management of CMN requires personalized monitoring and intervention, with pediatricians promoting sun safety and timely referrals to ensure better health for young patients with nevi.

Capillary malformations (CMs) are the most common vascular anomalies, composed of enlarged capillaries and venules with thickened perivascular cell coverage in skin and mucous membranes. These congenital anomalies represent an error in vascular development during embryogenesis. Most of the CMs occur without any syndromic findings; the association between CMs systemic anomalies in some patients, however, makes the recognition of additional syndrome features critical.

A pediatric dermatology expert working group performed a narrative review to describe care related to congenital melanocytic nevi (CMN) in neonates and infants. There are no published guidelines for most aspects of care, including routine skin care and visit intervals. Few guidelines exist for surgical management; newer recommendations favor conservative practice.

We present a case of alopecia associated with sleep-related rhythmic movement disorder (RMD) in an otherwise healthy 2-year-old boy. The alopecic patch he presented with on his scalp coincided with the location of repeated head banging in a video taken by the patient's mother. Alopecia secondary to RMD is an under recognized entity and should be included in the differential diagnosis of pediatric alopecia.

Arc welding is an occupation with exposure to intense bursts of UV radiation (UVR). Although industrial settings may be aware of UV light exposure during welding, physicians may be unaware of this source. We report 3 welders with skin diseases that may have been caused or exacerbated by occupational UV light exposure: refractory subacute cutaneous lupus erythematosus, diffuse actinic damage spared by the area protected by safety goggles, and squamous cell carcinoma developed outside of the area protected by a face shield.

Article Synopsis
  • Harlequin ichthyosis (HI) is a serious condition linked to high mortality rates.
  • Early treatment with systemic retinoids is common but its effectiveness is still debated.
  • Two newborns with severe mutations associated with HI survived and were discharged without using systemic retinoids, thanks to intensive care.

Introduction: Epidermolysis bullosa (EB) is a spectrum of mechanobullous disorders characterized by blistering following minor trauma or traction to the skin. Hearing loss in this population is poorly described in the otolaryngology literature, and its treatment oftentimes results in external auditory canal skin irritation.

Case Presentation: We present the case of a 26-year-old female with EB and mixed hearing loss unable to wear conventional hearing aids due to sequelae of the external auditory canals.

Importance: The notion that systemic isotretinoin taken within 6 to 12 months of cutaneous surgery contributes to abnormal scarring or delayed wound healing is widely taught and practiced; however, it is based on 3 small case series from the mid-1980s.

Objective: To evaluate the body of literature to provide evidence-based recommendations regarding the safety of procedural interventions performed either concurrently with, or immediately following the cessation of systemic isotretinoin therapy.

Evidence Review: A panel of national experts in pediatric dermatology, procedural/cosmetic dermatology, plastic surgery, scars, wound healing, acne, and isotretinoin was convened.

Vascular Lesions.

Pediatr Ann

August 2016

Vascular lesions in childhood are comprised of vascular tumors and vascular malformations. Vascular tumors encompass neoplasms of the vascular system, of which infantile hemangiomas (IHs) are the most common. Vascular malformations, on the other hand, consist of lesions due to anomalous development of the vascular system, including the capillary, venous, arterial, and lymphatic systems.

Congenital ichthyosiform erythroderma is an autosomal recessive ichthyosis characterized by severe scaling and erythroderma. We report a family of three siblings who were all born with a collodion membrane and presented with diffuse scaling and pruritus. All three children subsequently developed chronic cutaneous dermatophyte infections requiring oral antifungals.

Colonization with Staphylococcal aureus is markedly more frequent in individuals with atopic dermatitis (AD) than in unaffected individuals. Chronic scratching leads to worsening of an existing defect in the epidermal barrier, which can allow S. aureus invasion into the bloodstream and subsequent systemic infections.
