Chromonychia
Chromonychia (pronounced: kroh-moh-NIK-ee-uh) is a medical condition characterized by discoloration of the nails. The term is derived from the Greek words "chroma" meaning color and "onyx" meaning nail.
Definition
Chromonychia is a condition where the color, thickness, or texture of the nail changes. It can affect one or more nails and can occur on the hands or feet. The discoloration can range from white, yellow, green, blue, or black.
Causes
Chromonychia can be caused by a variety of factors including infections, injuries, systemic diseases, drugs, and poisons. It can also be a sign of underlying health conditions such as lung disease, heart disease, kidney disease, or diabetes.
Symptoms
The primary symptom of chromonychia is a change in the color of the nails. Other symptoms may include changes in the thickness or texture of the nails, pain, or separation of the nail from the nail bed.
Treatment
Treatment for chromonychia depends on the underlying cause. If the discoloration is due to an infection, antifungal or antibacterial medications may be prescribed. If it is due to a systemic disease, treatment of the underlying condition is necessary.
