Trachyonychia Associated with Alopecia Areata and Secondary Onychomycosis

The document reported a case of an 8-year-old girl with trachyonychia, characterized by twenty dystrophic nails associated with alopecia areata and secondary onychomycosis caused by trichophyton rubrum. Trachyonychia, an idiopathic nail inflammatory disorder, often occurs in children and can be linked to various conditions like alopecia areata, psoriasis, and atopic dermatitis. Diagnosis typically requires a biopsy, though it is not always necessary. Management focuses on the underlying disease, as trachyonychia often improves spontaneously without specific therapy. Onychomycosis is challenging to treat, and fungal eradication does not always restore nail structure, especially if dystrophy existed prior to infection.
