Nail and Cuticle Disorders

Nail and Cuticle Disorders encompass a wide range of structural, infectious, inflammatory, and systemic conditions that manifest in the nail unit. Though often overlooked in routine dermatologic evaluation, changes in the nail plate, matrix, bed, or surrounding cuticle can reveal early signs of systemic disease, nutritional imbalance, autoimmune activity, or localized infection. This topic holds increasing importance at every international Dermatology Conference, where advancements in diagnostic precision and minimally invasive management are expanding treatment possibilities. Closely related to nail unit pathology, this session emphasizes the nail as both a cosmetic structure and a valuable clinical indicator of overall health.

The session explores nail anatomy in detail, highlighting the matrix as the growth center responsible for plate formation. Disruptions in matrix activity can lead to ridging, pitting, leukonychia, or dystrophy. Cuticle inflammation, paronychia, and periungual infections are discussed as common yet potentially chronic concerns that require targeted therapy.

Fungal infections remain one of the most prevalent nail disorders worldwide. Accurate diagnosis through microscopy, culture, or molecular testing ensures appropriate antifungal selection and reduces recurrence. Inflammatory nail changes associated with psoriasis, lichen planus, and alopecia areata are reviewed, with emphasis on differentiating autoimmune pathology from infectious causes.

Systemic disease markers such as clubbing, splinter hemorrhages, and Beau’s lines are discussed to reinforce the importance of comprehensive nail examination. Cosmetic nail practices and trauma-related damage are also addressed, as repeated mechanical stress can compromise nail integrity.

Therapeutic strategies include topical and systemic antifungal therapy, intralesional corticosteroids for inflammatory conditions, and protective measures to maintain cuticle barrier function. Advances in laser therapy for onychomycosis and regenerative approaches for nail dystrophy illustrate emerging innovation.

By recognizing the nail unit as an integral component of dermatologic evaluation, clinicians can diagnose broader health concerns while delivering targeted treatment for localized disorders. This session enhances awareness, diagnostic skill, and therapeutic precision in nail and cuticle management.
