Pigmentation Disorders

The Diagnosis: Carotenemia

Laboratory parameters including thyroid function testing as well as total protein and bilirubin levels were within reference range. Testing revealed multiple food allergies to almonds, oranges, cashews, garlic, peanuts, and cantaloupe. The patient was treated with a dietary expansion based on his allergy testing.

ß-Carotene converts to vitamin A in the intestine and acts as a lipochrome. Lack of conversion can be noted as an inborn error of metabolism.¹ Many green, yellow, and orange fruits and vegetables contain ß-carotene, including carrots, sweet potatoes, squash, green beans, papayas, and pumpkins.^1-3 ß-Carotene also is used as a vitamin supplement⁴ or therapeutic agent in photosensitive disorders such as genetic porphyrias.⁵

ß-Carotene can accumulate in the stratum corneum and impart a yellow color to the skin when the circulating levels are high; this coloration is termed carotenemia.^1,4 Carotenemia is common in infants and young children who have diets rich in green and orange vegetable purees.⁶ Carotenemia limited to thick areas of the skin, such as the palms and soles, can be seen in adults who eat large amounts of carrots; generalized carotenemia is rare.^1,4

Carotenemia is a benign condition of excess cutaneous buildup of ß-carotene through excessive intake of carotene-rich foods^1-4 or nutritional supplements⁷ or through association with anorexia, liver disease, renal disease, hypothyroidism, or diabetes mellitus.^1,4,8,9 Carotene deposits usually are most notable in areas with thick stratum corneum, such as the nasolabial folds, palms, and soles, as opposed to areas such as the conjunctivae and mucosa.^1,4

Carotenemia may mimic jaundice and should be differentiated through scleral examination for icterus and bilirubin levels. Carotene levels can be tested but generally are unnecessary. Carotenemia can be seen in liver or renal disease and can exacerbate the yellow coloration seen in jaundiced individuals.^1,4,9

Because it is a benign condition, the pathology usually is limited to skin discoloration, as seen in our patient. Although this condition can be reversed with a modified diet, our patient had multiple food allergies that further restricted his vegetarian diet, thereby limiting the modifications that he was willing to make to his diet.

Dyschromias are one of the most common skin concerns among women and persons of color. In the April issue of Journal of Drugs in Dermatology, Dr. S.J. Kang and associates conducted an excellent study to determine whether racial or ethnic groups are treated differently for dyschromia.

The investigators searched the National Ambulatory Medical Care Survey (NAMCS) database for visits including the diagnosis of dyschromia (ICD-9 codes 709.00 or 709.09) during an 18-year period (1993-2010). They found 24.7 million visits for dyschromia and 5,531,000 patients with a sole diagnosis of dyschromia. Of those with a sole diagnosis of dyschromia, 76% were seen by a dermatologist, and more than half were female. Seventy-five percent were white, 11% African American, 7% Asian/Pacific Islander, and 9% Hispanic, although Asians demonstrated the highest number of visits per 100,000 persons.

In this review, hydroquinone monotherapy was the most commonly prescribed medication by dermatologists. Combination therapy with hydroquinone plus a retinoid and corticosteroid was utilized for women 10 times more than for men. African American patients were less likely to be prescribed combination therapy or receive procedures (such as cryotherapy, chemical peels or lasers). Additionally, sunscreens were recommended less often to black and Asian patients, compared with white patients.

While the underlying reason for dyschromia plays a role in the type of treatment given, overall combination therapies are often more effective than therapy with hydroquinone alone. This study demonstrates that combination therapy may be under-utilized in patients of color.

In my practice, I find that unless the patient’s skin is completely hydroquinone-naive, combination therapy with hydroquinone, retinoid, and corticosteroid is often a first-line treatment that may achieve faster results. Sun protection is a vital component in the treatment of dyschromia, and it is recommended for every patient, regardless of race or ethnicity. Nonhydroquinone topical agents containing ingredients such as kojic acid, arbutin, licorice, niacinamide, resveratrol, and superficial chemical peels are also used in all ethnic groups. In my Asian, Hispanic, and African American or darker-skinned patients, I do use caution with deeper peels and lasers and often perform a test spot first if this type of therapy is considered.

DENVER – Vitiligo has been known for thousands of years, but only in the past six decades have researchers begun to better understand it and uncover genes associated with the disorder.

Dr. Richard A. Spritz, one of the leaders in vitiligo research, says that scientists are very close to understanding the condition’s pathogenesis. He is embarking on another analysis of data from a large genetic study, which could double the number of known vitiligo genes, putting the disorder on par with other autoimmune diseases such as type 1 diabetes and rheumatoid arthritis.

At the Society of Pediatric Dermatology’s annual meeting, held immediately before the annual meeting of the American Academy of Dermatology, Dr. Spritz spoke about what is known so far about vitiligo and what the future holds. Dr. Spritz is professor and director of the Human Medical Genetics and Genomics Program at the University of Colorado, Aurora.

Many dermatologists continue to battle an overwashing epidemic. From bar soaps to antibacterial washes, dermatologists continue to educate patients that the extensive lather, the alkaline pH, and the antibacterial components of our washing rituals can strip the natural oils from the skin and leave it dry, cracked, and damaged.

This phenomenon is well reported in the literature, and industry has taken notice by developing more "no-soap" soaps than ever before.

But does the same philosophy apply to hair care practices? Hair washing is more complicated, particularly in skin of color patients.

Overwashing the hair often leads to dry hair, split ends, and the need for compensatory conditioners to replace lost moisture. In African American hair, especially that of patients who use chemical or heat treatments, the lost oil and sebum from overwashing can cause even more damage.

Many skin of color patients wash their hair infrequently to protect it from breakage, and they may use topical oils to smooth and protect the fragile hair shaft.

However, can underwashing the scalp and hair cause problems? Yes, in some cases.

You might see African American patients in your practice who are suffering from scalp folliculitis, itchy scalp, seborrheic dermatitis, or alopecia that can be traced to infrequent hair washing. The infrequency of washing and the application of oils to the hair does help the hair shaft, but the buildup of oils and sebum on the scalp itself can lead to scalp inflammation, follicular plugging, extensive seborrhea, acneiform eruptions, and folliculitis.

Depending on its level and degree, the inflammation can cause pruritus and burning of the scalp and can even lead to temporary or permanent hair loss. Although topical and oral antibiotics, topical steroids, and medicated shampoos do help, proper washing also plays an important preventative role.

For skin of color patients with some of the chronic scalp problems mentioned above, decreasing heat and chemical treatments, along with increasing hair washing to two or three times a week can help prevent scalp dermatitides without compromising the hair integrity. In addition, the use of sulfate-free shampoos, use of shampoo on the scalp only (without lathering the ends of the hair), or use of a dry shampoo between washes can help control the oil and product buildup on the scalp itself.

Ultimately, it may take some trial and error to find the right hair washing regimen for skin of color patients. Determining how often to wash the scalp depends on many patient-specific factors including ethnicity, hair type, frequency of chemical and heat treatments, cost, and level of scalp inflammation. Experimenting with new hair care products and possibly a new hairstyle also may be part of a successful treatment plan.

Dry skin occurs throughout the year, but for many people it’s most prevalent and problematic in winter. Cold temperatures, low humidity, and strong, harsh winds deplete the skin of its natural lipid layer, which would normally help keep the skin from drying out. Skin of color in particular, can become very flaky, dry, and "ashy" in the winter. Differences in the stratum corneum barrier in skin of color may contribute to the propensity toward ashiness.

The barrier function of the skin depends on the structure of the corneocytes, lipid content, and transepidermal water loss. Compared with skin in white people, black skin has more corneocyte layers and a more compact stratum corneum with greater intercellular cohesiveness. The epidermal barrier in darker skin has been shown to be stronger when exposed to mechanical or chemical challenge. Although the size of the individual corneocytes is the same in black and white skin, the desquamation rate in certain locations is higher in black skin. This is likely due to increased desquamatory enzyme levels such as cathepsin L2 in the lamellar granules of darker pigmented individuals leading to an ashy manifestation of the skin.

Black skin also has the highest sebum content of all ethnicities, but has the lowest ceramide level, and is thus the most susceptible to transepidermal water loss and xerosis of any ethnic group. Of note, one study has shown that the use of a certain type of fatty acid body wash or a synthetic "syndet" bar reduced ashiness.

Although no large, multiethnic group studies have been performed to examine the skin barrier physiologic properties and their relation to clinical signs of disease, these small studies do shed light on some of the ethnic variation in skin barrier function.

In clinical practice, these small variations should play a role in personalized treatment regimens for common conditions such as acne and atopic dermatitis. In my practice, black patients with acne often have high sebum content, but they cannot tolerate drying medications such as benzoyl peroxide because of their skin sensitivity and intolerance to skin drying. These patients often also present with ashy, dry skin in certain areas, and oily, acne-prone skin in other areas, leading to more complex skin care regimens. Understanding these basic concepts can help better tailor our basic skin treatments and education for skin of color patients in the winter and throughout the year.

These patients often also present with ashy, dry skin in certain areas, and oily, acne-prone skin in other areas, leading to more complex skin care regimens. Understanding these basic concepts can help better tailor our basic skin treatments and education for skin of color patients in the winter and throughout the year.

Dry skin occurs throughout the year, but for many people it’s most prevalent and problematic in winter. Cold temperatures, low humidity, and strong, harsh winds deplete the skin of its natural lipid layer, which would normally help keep the skin from drying out. Skin of color in particular, can become very flaky, dry, and "ashy" in the winter. Differences in the stratum corneum barrier in skin of color may contribute to the propensity toward ashiness.

The barrier function of the skin depends on the structure of the corneocytes, lipid content, and transepidermal water loss. Compared with skin in white people, black skin has more corneocyte layers and a more compact stratum corneum with greater intercellular cohesiveness. The epidermal barrier in darker skin has been shown to be stronger when exposed to mechanical or chemical challenge. Although the size of the individual corneocytes is the same in black and white skin, the desquamation rate in certain locations is higher in black skin. This is likely due to increased desquamatory enzyme levels such as cathepsin L2 in the lamellar granules of darker pigmented individuals leading to an ashy manifestation of the skin.

Black skin also has the highest sebum content of all ethnicities, but has the lowest ceramide level, and is thus the most susceptible to transepidermal water loss and xerosis of any ethnic group. Of note, one study has shown that the use of a certain type of fatty acid body wash or a synthetic "syndet" bar reduced ashiness.

Although no large, multiethnic group studies have been performed to examine the skin barrier physiologic properties and their relation to clinical signs of disease, these small studies do shed light on some of the ethnic variation in skin barrier function.

In clinical practice, these small variations should play a role in personalized treatment regimens for common conditions such as acne and atopic dermatitis. In my practice, black patients with acne often have high sebum content, but they cannot tolerate drying medications such as benzoyl peroxide because of their skin sensitivity and intolerance to skin drying. These patients often also present with ashy, dry skin in certain areas, and oily, acne-prone skin in other areas, leading to more complex skin care regimens.
