Abstract
The word trachyonychia means rough nails. Trachyonychia can present in opaque and shiny variants. This is referred to as opaque trachyonychia and shiny trachyonychia. The diagnosis of trachyonychia is clinical and a nail unit biopsy is not required Trachyonychia is a benign disease that may regress spontaneously. The most common causes of trachyonychia are alopecia areata, lichen planus, and psoriasis. A variety of treatment options exist, and the treatment should be conservative since this is a non-scarring condition.
