Abstract:
Trachyonychia may be idiopathic, familial, or occur in association with other dermatologic conditions. It manifests in two distinct forms: opaque (more severe) and shiny trachyonychia, or as a combination of both. The condition typically affects children, with peak prevalence between ages 3 and 12, but it may occur at any age and in both sexes. It can be inherited in an autosomal dominant pattern and has been documented in monozygotic twins. While frequently idiopathic, trachyonychia may be associated with alopecia areata, eczema, lichen planus, psoriasis, or vitiligo. Diagnosis can be challenging when no other clinical features are present. A thorough dermatologic eval uation is essential to identify treatable underlying conditions. There is no universally accepted treatment, and the disease is often self-limiting, with reassurance being a critical part of management.
