Carotenodermia

Carotenodermia is a benign and reversible medical condition where the skin turns yellow-orange due to excessive consumption of carotene-rich foods. This condition is primarily cosmetic and does not cause harm to the body. Carotenodermia is often mistaken for jaundice, a more serious condition that indicates liver dysfunction or other health issues. However, unlike jaundice, carotenodermia does not result in yellowing of the sclera (the white part of the eyes).

Causes

Carotenodermia is caused by the accumulation of carotene, a type of Vitamin A precursor found in various fruits and vegetables. Foods particularly high in carotene include carrots, sweet potatoes, pumpkins, and mangoes. The condition can also occur from the excessive intake of carotene supplements. The body converts carotene to Vitamin A, an essential nutrient, but when consumed in large amounts, excess carotene is deposited in the skin’s outermost layer, leading to the characteristic yellow-orange hue.

Symptoms

The primary symptom of carotenodermia is the yellow-orange discoloration of the skin, particularly noticeable on the palms, soles, knees, and nasolabial folds. The condition is not associated with any physical discomfort or harm. It is important to differentiate carotenodermia from jaundice by checking the coloration of the sclera; in carotenodermia, the sclera remains white.

Diagnosis

Diagnosis of carotenodermia is primarily clinical, based on the patient's history of dietary intake and the physical examination findings. Blood tests may be conducted to measure carotene levels and to rule out jaundice by checking liver function tests.

Treatment

The treatment for carotenodermia involves reducing the intake of carotene-rich foods and supplements. Once the consumption of carotene is decreased, the skin color gradually returns to normal, usually within a few weeks to months, depending on the extent of carotene accumulation.

Prevention

Preventing carotenodermia is straightforward and involves moderating the intake of carotene-rich foods and supplements. A balanced diet that includes a variety of fruits and vegetables without excessive consumption of any single source of carotene is advisable.
