Beau's Lines

Beau's lines are horizontal depressions in the fingernail or toenail that run from side to side. They are named after Joseph Honoré Simon Beau, a French physician who first described them in 1846. Beau's lines can be caused by a variety of medical conditions, including systemic diseases, local nail trauma, and certain medications.

Causes of Beau's Lines

Beau's lines can be caused by a variety of medical conditions, including:

• Systemic diseases, such as diabetes, peripheral vascular disease, and malnutrition
• Local nail trauma, such as a nail injury or infection
• Certain medications, such as chemotherapy drugs and antiretroviral drugs

Diagnosis of Beau's Lines

Beau's lines are usually diagnosed during a physical examination. Your doctor may also order tests to determine the underlying cause of the lines. These tests may include blood tests, X-rays, and other imaging tests.

Outlook

Beau's lines usually grow out with the nail and do not require treatment. However, if the lines are caused by an underlying medical condition, it is important to treat the condition to prevent further complications.

What Are the Symptoms of Beau's Lines?

The most common symptom of Beau's lines is the presence of horizontal depressions in the fingernail or toenail. These lines may be deep or shallow, and they may be single or multiple. They may also be accompanied by other symptoms, such as discoloration of the nail, brittle nails, and ridges in the nail.

What Causes Beau's Lines?

Beau's lines can be caused by a variety of medical conditions, including trauma, infection, and systemic diseases. Trauma to the nail can cause Beau's lines, as can certain infections, such as syphilis, mumps, and measles. Systemic diseases, such as diabetes, can also cause Beau's lines. In some cases, the cause of Beau's lines is unknown.

How Are Beau's Lines Diagnosed?

Beau's lines are usually diagnosed by a physical examination of the nails. Your doctor may also order tests to rule out any underlying medical conditions that may be causing the lines. These tests may include blood tests, X-rays, and other imaging tests.

How Are Beau's Lines Treated?

The treatment for Beau's lines depends on the underlying cause. If the lines are caused by trauma, they may resolve on their own. If the lines are caused by an infection, your doctor may prescribe antibiotics. If the lines are caused by a systemic disease, your doctor may recommend treatment for the underlying condition.

Injury or Trauma

Injury or trauma to the nail bed can cause Beau's lines. This can include a direct injury to the nail, such as dropping something heavy on the nail, or an indirect injury, such as a severe jamming of the finger or toe. In some cases, the injury may be so severe that the nail plate is completely destroyed.

Systemic Illness

Systemic illnesses, such as diabetes, can cause Beau's lines. This is because the body's ability to produce new nail cells is impaired, leading to a disruption in the growth of the nail plate. Other illnesses that can cause Beau's lines include kidney disease, malnutrition, and certain types of infections.

Medications

Certain medications can also cause Beau's lines. These include chemotherapy drugs, antimalarial drugs, and some antibiotics. In some cases, the lines may appear after the medication has been stopped.

Age

As people age, their nails may become more brittle and prone to Beau's lines. This is because the body's ability to produce new nail cells decreases with age.

Exposure to Chemicals

Exposure to certain chemicals, such as nail polish remover, can cause Beau's lines. This is because the chemicals can damage the nail plate, leading to a disruption in the growth of the nail.

What Causes Beau's Lines?

Beau's lines can be caused by a variety of medical conditions, including trauma, infection, and systemic diseases. Trauma to the nail bed can cause Beau's lines, such as when the nail is hit with a hammer or other object. Infections, such as bacterial or fungal infections, can also cause Beau's lines. Systemic diseases, such as diabetes, can also cause Beau's lines.

How Are Beau's Lines Diagnosed?
