Primary and secondary carotenoderma can coexist in the same patient. This condition is called argyria. The primary serum carotenoids are beta-carotene, lycopene, and lutein. Diagnosis Diagnosing jaundice. Carotenoderma is deliberately caused by beta-carotenoid treatment of certain photo-sensitive dermatitis diseases such as erythropoietic protoporphyria, where beta carotene is prescribed in quantities which discolor the skin. Yellow feet are not usually a cause for concern. Diabetes, hypothyroidism, and liver and kidney disease may alter carotene levels in the body and lead to physical symptoms. Canthaxanthin and astaxanthin are naturally occurring carotenoids that are used in the British and US food industry to add color to foods such as sausage and fish. Processing and homogenizing causes carotene to become more available for absorption.

Carotenemia is most commonly seen in infants fed too much mashed carrots and adults consuming high quantities of carrots, carrot juice, or beta carotene in supplement form. Carotenosis is a benign and reversible medical condition where an excess of dietary carotenoids results in orange discoloration of the outermost skin layer. Hypothyroidism, diabetes mellitus, hepatic and renal diseases may be associated with carotenemia… Carotenemia is usually caused by an excess of carotene, a natural food pigment, which occurs in orange foods such as carrots, pumpkins, sweet potato (yams) This change takes approximately 4 to 7 weeks to be recognized clinically. The discoloration is most easily observed in light-skinned people and may be mistaken for jaundice. Carotenemia may mimic jaundice and should be differentiated through scleral examination for icterus and bilirubin levels. As to underlying disorders in secondary carotinemia and carotenoderma, treatment depends wholly on the cause. This is of particular interest because jaundice and carotenoderma can coexist in the same patient. These include hepatitis, urticaria, aplastic anemia, and a retinopathy characterized by yellow deposits and subsequent visual field defects.[11]. The primary factor differentiating carotenoderma from jaundice is the characteristic sparing of the sclerae in carotenoderma, which would be involved in jaundice if the bilirubin is at a level to cause skin findings. Carotenodermia (also carotenaemia, carotenemia or hypercarotenemia) is a yellowish discoloration of the skin, most often occurring in the palms of the hands and soles of the feet as a result of high levels of carotene in the body.This symptom, also known as xanthosis cutis, is reversible and harmless. Excessive consumption of lycopene, a plant pigment similar to carotene and present in tomatoes, can cause a deep orange discoloration of the skin. Carotenemia is a usually harmless condition where a child or adult gets orange-colored skin. Carotenemia is a benign condition; vitamin A poisoning does not occur despite massive doses of carotene because the conversion of carotene to vitamin A is slow. In contrast to jaundice, carotenoderma is reported to be better observed under artificial light. Beta-carotene is found in carotene-rich foods like carrots, squash and sweet potatoes. [10] A true association between Alzheimer's disease and carotenoderma is unclear at this time.

Jaundice is a term used to describe the yellowing of the skin and the whites of the eyes. This includes the palms, soles, knees, and nasolabial folds, although the discoloration can be generalized. Primary carotenoderma is from increased oral ingestion of carotenoids, whereas secondary carotenoderma is caused from underlying disease states that increase serum carotenoids with normal oral intake of these compounds. ... More ». Historically, carotenemia is relatively an old condition that was mentioned in a few old medical case reports. Disease states associated with carotenoderma include hypothyroidism, diabetes mellitus, anorexia nervosa, nephrotic syndrome, and liver disease. One instance of carotenosis being featured in popular culture is The Magic School Bus episode "Goes Cellular", where Arnold has his skin dyed orange as a result of excessive consumption of carotene-rich "Seaweedies" the night he is to receive a geology-related award. From there they are transported in the plasma into the peripheral tissues. The terms xanthoderma (yellow skin) and carotenosis are also used. Canthaxanthin has been used in over-the-counter “tanning pills” in the United States and Europe, but is not currently Food and Drug Administration (FDA)-approved for this purpose in the United States because of its adverse effects. [citation needed] Carotenoids contribute to normal-appearing human skin color, and are a significant component of physiologic ultraviolet photoprotection.[4]. Carotenemia is a clinical condition characterized by yellow pigmentation of the skin (xanthoderma) and increased beta-carotene levels in the blood. It is of note that kidney dysfunction in general is associated with hypercarotenemia as a result of decreased excretion of carotenoids. [5] Carotenemia is more easily appreciated in light-complexioned people, and it may present chiefly as an orange discolouration of the palms and the soles in more darkly pigmented persons. Carotenemia is a benign and completely harmless condition, which arises as a result of excess levels of carotene in the body. It's caused by a build-up of a substance called bilirubin. Carotenemia most commonly occurs in vegetarians and young children with light skin. Foods associated with high levels of carotenoids[8] include: Carotenoids are deposited in the intercellular lipids of the stratum corneum, and the color change is most prominent in regions of increased sweating and thickness of this layer.

Carotenemia is a clinical condition characterized by yellow pigmentation of the skin (xanthoderma) often on the feet and palms of adults, and increased beta-carotene levels in the blood. Argyria and chrysiasis, however, are irreversible, unlike carotenosis. Copyright © 2018 RevMax Media Pty Ltd.

The sclerae always are spared, which readily distinguishes carotenemia from jaundice. Carotenemia is not associated with Vitamin A poisoning, even though carotene is converted to Vitamin A during the digestive process, because the conversion is slow. It occurs in the absence of yellow discoloration of the sclera. Carotene levels can be tested but generally are unnecessary. Carotenemia is a benign condition; hence, further diagnostic testing is unnecessary. Carotenemia is the term used for increased beta-carotene levels in the blood and yellow pigmentation of the skin. In a recent meta analysis of these treatments, however, the effectiveness of the treatment has been called into question.[7]. Finally, in certain disease states, the metabolism and conversion of carotenoids to retinol is slowed, which can lead to decreased clearance and increased plasma levels. Excessive consumption of fruits and vegetables high in carotene content is often the culprit. These high doses of beta carotene have been found to be harmless in studies, though cosmetically displeasing to some. In these cases of carotenemia, serum levels of vitamin A may be normal or elevated, although never high enough to cause hypervitaminosis A.

[6] Carotenemia does not cause selective orange discoloration of the conjunctival membranes over the sclerae (whites of the eyes), and thus is usually easy to distinguish from the yellowing of the skin and conjunctiva caused by bile pigments in states of jaundice.

Carotenemia and carotenoderma is in itself harmless, and does not require treatment. Carotenemia is almost always associated with diet, but it can occasionally be a sign of a more serious condition. A small 2.5 ounce jar of baby food sweet potatoes or carrots contains about 400-500% of an infant's recommended daily value of carotene.

Although carotenemia occurs mostly in infants when they are fed too much pureed carrot baby food, it can occur in adults as well. Average adult intake in the U.S. around 2.3 mg/day. In hypothyroidism and diabetes mellitus, the underlying mechanism of hypercarotenemia is thought to be both impaired conversion of beta-carotene into retinol and the associated increased serum lipids. Increased serum lipids also cause hypercarotenemia because there are increased circulating lipoproteins that contain bound carotenoids. The primary serum carotenoids are beta-carotene, lycopene, and lutein. A recent clinical observation differentiated these entities.The patient was a 28-year-old woman who was referred for evaluation of a yellow color to her skin. Carotenemia is a condition that arises with high levels of carotene in the body. The terms xanthoderma (yellow skin) and carotenosis are also used.
