Primary anetoderma is a rare skin condition that is not curable. However, there are medications that can help to reduce the symptoms. These include topical corticosteroids, topical calcineurin inhibitors, and oral retinoids. In some cases, surgery may be recommended to remove the affected skin.

The exact cause of primary anetoderma is unknown, but some risk factors may include:

• Age: Primary anetoderma is more common in adults between the ages of 20 and 40.

• Gender: Women are more likely to develop primary anetoderma than men.

• Family history: Primary anetoderma may be more common in people with a family history of the condition.

• Certain medications: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antibiotics, may increase the risk of developing primary anetoderma.

• Sun exposure: Prolonged sun exposure may increase the risk of developing primary anetoderma.

The treatments for primary anetoderma include topical corticosteroids, intralesional corticosteroids, topical calcineurin inhibitors, phototherapy, and systemic retinoids.

The exact cause of primary anetoderma is unknown. However, it is believed to be related to a defect in the elastic fibers of the skin. It is thought to be an autoimmune disorder, meaning that the body's immune system mistakenly attacks its own tissues. Other possible causes include genetic factors, certain medications, and infections.

The primary symptoms of primary anetoderma are smooth, round or oval patches of skin that are slightly raised and have a wrinkled or dimpled appearance. These patches may be red, white, or a combination of both. They can range in size from a few millimeters to several centimeters in diameter. Other symptoms may include itching, burning, or tenderness in the affected area.

Primary anetoderma is a rare skin condition characterized by the formation of multiple, round, atrophic patches on the skin. These patches are usually found on the trunk, arms, and legs, and can range in size from a few millimeters to several centimeters. The patches are usually smooth and hairless, and may be slightly depressed or raised. Primary anetoderma is not associated with any other medical conditions, and is not contagious.
