Article Synopsis
- Atopic dermatitis (AD) is a long-lasting skin condition that can start in childhood and continue into adulthood, or emerge for the first time in adults.
- A study was conducted to compare the clinical characteristics of adults with either pediatric-onset or adult-onset AD using medical records from a large academic center.
- Results showed that adults with adult-onset AD had different signs and symptoms compared to those with pediatric-onset AD, suggesting that current diagnostic criteria may not fully recognize adult-onset AD, potentially leading to underdiagnosis.

Higher Expression of Lympho-epithelial Kazal-type-Related Inhibitor-1 Fragments and Decreased Desquamation in the Lesional Skin of Nummular Eczema.
Acta Derm Venereol
March 2024
Department of Dermatology, Seoul National University College of Medicine, Seoul, Republic of Korea; Institute of Human-Environment Interface Biology, Medical Research Center, Seoul National University, Seoul, Republic of Korea; Laboratory of Cutaneous Aging Research, Biomedical Research Institute, Seoul National University Hospital, Seoul, Republic of Korea; Institute on Aging, Seoul National University, Seoul, Republic of Korea.
Article Synopsis
- Nummular eczema, a chronic skin condition marked by coin-shaped lesions, has unclear underlying mechanisms despite being recognized since 1857.
- A study analyzing skin samples from affected and healthy individuals revealed that the desquamation process, which is essential for skin renewal, is impaired in nummular eczema due to disorganization and increased expression of certain skin proteins.
- The research also indicated that higher levels of an inhibitor (Kazal-type-related inhibitor-1) in affected skin might prevent the normal breakdown of structures that facilitate skin shedding, contributing to delayed desquamation and symptom persistence.

The neglected twin: Nummular eczema is a variant of atopic dermatitis with codominant T2/T17 immune response.
J Allergy Clin Immunol
August 2023
Department of Medicine, Division of Dermatology and Venerology, Karolinska Institute, Stockholm, Sweden; Department of Dermatology and Venerology, Medical Center, University of Freiburg, Freiburg, Germany.
Background: Nummular eczema (NE) is a common chronic inflammatory skin disease characterized by multiple, pruritic, discoid-shaped lesions. Since the underlying immune mechanisms are not fully understood, it is unclear whether NE should be regarded as variant of atopic dermatitis (AD) or a distinct disease.
Objective: We compared the clinical, histopathologic, and molecular signatures of NE with that of type 2 and type 3 skin diseases.
Association of Adult Atopic Dermatitis Severity With Bacterial, Viral, and Fungal Skin Infections.
Dermatitis
March 2023
†Department of Dermatology, The George Washington University School of Medicine and Health Sciences, Washington, District of Columbia, USA.
Article Synopsis
- The study aimed to investigate the connection between the severity and characteristics of atopic dermatitis (AD) and the occurrence of skin infections in adults, involving 559 participants.
- Results showed that patients with moderate to severe AD were significantly more likely to have skin infections, particularly bacterial ones, compared to those with mild AD.
- The findings suggest that while skin infections relate to AD severity, they do not correlate with specific AD phenotypes, indicating that better management of AD could potentially reduce the risk of skin infections.

Characterization of Classical Flexural and Nummular Forms of Atopic Dermatitis in Childhood with Regard to Anamnestic, Clinical and Epidermal Barrier Aspects.
Acta Derm Venereol
March 2022
Department of Dermatology, Venereology and Allergology, University Hospital Schleswig-Holstein, Campus Kiel, Arnold-Heller Str. 3, DE-24105 Kiel, Germany.
Article Synopsis
- Nummular and classical atopic dermatitis have different appearances but share some underlying characteristics; this study aimed to explore their differences and similarities in children.
- Researchers examined 10 children with nummular atopic dermatitis, 14 with classical atopic dermatitis, and 10 healthy controls, finding that nummular dermatitis occurred more in boys and less often in infants compared to classical dermatitis.
- Both types showed issues like lower skin hydration and higher moisture loss, but nummular dermatitis showed more variation in eczema patterns and more severe keratosis pilaris, suggesting that they should be treated as separate conditions with distinct therapeutic strategies.
