Trachonychia
Trachonychia
Trachonychia (pronounced truh-KOH-nee-uh), also known as Twenty-Nail Dystrophy, is a condition characterized by roughness or ridging on the nails. The term "trachonychia" is derived from the Greek words "trachy," meaning rough, and "onyx," meaning nail.
Definition
Trachonychia is a medical condition that affects the nails on both the hands and feet. It is characterized by longitudinal ridging and roughness on the nails, which can appear dull, sandpaper-like, and can be whitish or cloudy in color.
Symptoms
The primary symptom of trachonychia is the change in the appearance of the nails. The nails may become rough, ridged, and may lose their shine. In some cases, the nails may also become thin and brittle, and there may be associated pain or tenderness.
Causes
Trachonychia is often associated with other skin conditions such as lichen planus, psoriasis, atopic dermatitis, or alopecia areata. It can also occur as an isolated condition without any associated skin disorders. The exact cause of trachonychia is not known, but it is thought to be due to an abnormality in the nail matrix, the part of the nail bed that produces the nail.
Treatment
Treatment for trachonychia primarily involves managing any underlying skin conditions. This may involve the use of topical steroids, emollients, or other medications. In some cases, no treatment is necessary as the condition can resolve on its own.
