Dermatology Concerns In Skin of Color Patients

By | Skin of Color Update Agenda | No Comments

During the 16th Annual ODAC Dermatology, Aesthetics and Surgical Conference, I had the pleasure of taking part in the Resident Career Development Mentorship Program (a program supported by an educational grant from Sun Pharmaceutical Industries, Inc.). and was paired with Dr. Andrew Alexis, Chair of Dermatology at Mount Sinai St. Luke’s and Mount Sinai West in New York City.

During a 45-minute working group session, Dr. Alexis covered three main themes: common dermatologic disorders with unique manifestations in skin of color, disorders that disproportionately affect patients of color and therapeutic nuances and unique treatment concerns in skin of color. Here are the main takeaways and pearls from this session.

Common Disorders With Unique Manifestations

Acne

Post-inflammatory hyperpigmentation is a major concern in patients of color and many times more bothersome than acne itself.  It is important to use agents that will treat both acne and PIH. Retinoids can be very effective –tretinoin, tazarotene and adapalene have been shown effect for PIH. Azelaic acid can be a good add on for patients with PIH.

Dr. Alexis doesn’t use much hydroquinone for these patients – the macules left behind by acne are usually too small to avoid creating halos around the lesion.  Chemical peels have been demonstrated to improve PIH in small studies.  The risks are higher in skin of color, so it advisable to stick to superficial peeling agents. Avoiding irritation is essential since it can lead to more dyspigmentation.

Maximize tolerability – adapalene and low concentration tretinoin or tazarotene are a good starting point.  Eliminate any irritating scrubs and other skincare products.  Use noncomedogenic moisturizers concurrently.

Disorders That Disproportionately Affect Patients of Color

Pseudofolliculitis barbae

Findings consist of papules and prominent hyperpigmentation.  This process can also trigger keloid formation. While more common in men, women with hirsutism may also develop PFB. It results from a foreign body reaction to hair reentering the dermis.

A very effective strategy is to discontinue shaving.  You may have to write letters to some patients’ employers in order to excuse them from shaving (Dr. Alexis keeps a form letter on file in his practice).

Chemical depilatory agents are a decent option.  Barium sulfide powder and calcium thioglycolate cream can be used every 2-4 days.  However, they can cause irritant dermatitis. Some patients may also find success by modifying their shaving practices.  Don’t assume your patients know how to shave – educate them.  Electric clippers are a good option – have patients leave 0.5-1 mm stubble. Traditionally single blade manual razors have been recommended.

One study sought to quantify the impact of blade number on PFB – 90 African American men were assigned to shave with a different number of blades.  There was no difference between any of the groups and everyone got better.

A small study showed decreased severity of PFB with daily shaving vs twice weekly shaving.

Dr. Alexis has a handout for patients with shaving instructions: before shaving use a mild cleanser and use a wash cloth in a circular motion to free hairs.  Use clean and sharp razor, shaving in the direction of hair growth.  Use topicals after such as clindamycin lotion or topical dapsone.  Apply a topical retinoid nightly. Avoid pulling or plucking embedded hairs, shaving against the grain.

Updates on the Prevention and Management of Keloids

By | Skin of Color Update Agenda | No Comments

This article features a recap of Dr. Hilary Baldwin’s talk on the etiology, risk factors, and treatment of keloids at the 2018 Skin of Color Seminar Series, now known as the Skin of Color Update. Dr. Bridget Kaufman, onsite correspondent for the meeting, shares highlights directly from the talk. Dr. Baldwin focused on earlobe keloids in particular, which may present with several different morphologies: anterior button, posterior button, wraparound, dumbbell, and lobular. *Clinical pearls* from this session are bolded, underlined and marked with asterisks.

Dr. Baldwin started by discussing why some patients develop keloids and others do not. Based on a study of 220 patients at Kings County Hospital, there appears to be no difference in rate of cartilage piercing, metal sensitivity, types of earrings worn, piercing method, hormonal influences, or age at piercing between keloid formers and non-keloid formers.  In the keloid former group, 12.8% of patients developed keloids at the first piercing, and the risk of keloid formation dramatically increased at each piercing thereafter (70.2% risk for 2nd piercing).

Important Points:

*Ear pierces on babies have a 0% risk of keloids*

*Piercings done pre-menarche have a significantly lower risk of keloids than those performed post-menarche*

*First pierces rarely keloid*

*The chances of subsequent pierce keloiding in a keloid former is at least 20% or higher*

Successful Treatment of Keloid With Fractionated Carbon Dioxide (CO2) Laser and Laser-Assisted Drug Delivery of Triamcinolone Acetonide Ointment in an African-American Man

Keloids are fibrous growths that occur as a result of abnormal response to dermal injury. Keloids are cosmetically disfiguring and may impair function, often resulting in decreased patient quality-of-life. Treatment of keloids remains challenging, and rate of recurrence is high. We present a case of a 39-year-old African-American man (Fitzpatrick VI) with a 10-year history of keloid, who was successfully treated with eight sessions of fractionated carbon dioxide (CO2) laser immediately followed by laser-assisted drug delivery (LADD) of topical triamcinolone acetonide (TAC) ointment and review the medical literature on fractionated CO2 laser treatment of keloids. To the best of our knowledge, this is the first report of successful treatment of a keloid using combination therapy of fractionated CO2 laser and LADD with topical TAC ointment in an African-American man (Fitzpatrick VI) with excellent cosmetic results sustained at 22 months post-treatment. We believe that this combination treatment modality may be safe and efficacious for keloids in skin of color (Fitzpatrick IV-VI) and other patients. This case highlights the ability of laser surgeons to safely use fractionated CO2 lasers in patients of all skin colors.
