Aurantiasis cutis

Aurantiasis cutis is a rare medical condition characterized by the deposition of carotenoids in the skin, resulting in a yellow-orange discoloration. The condition is often associated with excessive consumption of carotenoid-rich foods, such as carrots, pumpkins, and oranges, but can also be a symptom of certain diseases, such as hypothyroidism and diabetes mellitus.

Causes

The primary cause of aurantiasis cutis is the excessive consumption of carotenoid-rich foods. Carotenoids are a type of pigment found in many fruits and vegetables, and are responsible for their vibrant colors. When consumed in large amounts, these pigments can accumulate in the skin, leading to the characteristic yellow-orange discoloration of aurantiasis cutis.

In addition to dietary factors, certain diseases can also cause aurantiasis cutis. These include hypothyroidism, a condition in which the thyroid gland does not produce enough hormones, and diabetes mellitus, a metabolic disorder characterized by high blood sugar levels. Both of these conditions can affect the body's ability to metabolize carotenoids, leading to their accumulation in the skin.

Symptoms

The main symptom of aurantiasis cutis is a yellow-orange discoloration of the skin. This discoloration is most noticeable on the palms of the hands and the soles of the feet, but can also affect other areas of the body. Other symptoms can include fatigue, weight loss, and a decreased appetite.

Diagnosis

Aurantiasis cutis is typically diagnosed based on the characteristic skin discoloration and a history of excessive consumption of carotenoid-rich foods or the presence of a disease that can cause the condition. Blood tests may also be performed to measure the levels of carotenoids in the body.

Treatment

The treatment for aurantiasis cutis primarily involves reducing the intake of carotenoid-rich foods. In cases where the condition is caused by a disease, treating the underlying disease can also help to reduce the skin discoloration. In some cases, the skin discoloration may fade over time once the intake of carotenoids is reduced or the underlying disease is treated.
