NEW YORK –
Skin diseases pose a greater risk of both hyper- and hypopigmentation in patients with darker skin types, but the fear and concern that this raises for permanent disfigurement is not limited to Blacks, Dr. Heath, assistant professor of pediatric dermatology at Temple University, Philadelphia, said at the Skin of Color Update 2023.
“Culturally, pigmentation changes can be huge. For people of Indian descent, for example, pigmentary changes like light spots on the skin might be an obstacle to marriage, so it can really be life changing,” she added.
In patients with darker skin tones presenting with an inflammatory skin disease, such as AD or psoriasis, Dr. Heath advised asking specifically about change in skin tone even if it is not readily apparent. In pediatric patients, it is also appropriate to include parents in this conversation.
Consider the parent’s perspective
“When you are taking care of a child or adolescent, the patient is likely to be concerned about changes in pigmentation, but it is important to remember that the adult in the room might have had their own journey with brown skin and has dealt with the burden of pigment changes,” Dr. Heath said.
For the parent, the pigmentation changes, rather than the inflammation, might be the governing issue and the reason that he or she brought the child to the clinician. Dr. Heath suggested that it is important for caregivers to explicitly recognize their concern, explain that addressing the pigmentary changes is part of the treatment plan, and to create realistic expectations about how long pigmentary changes will take to resolve.
As an example, Dr. Heath recounted a difficult case of a Black infant with disseminated hyperpigmentation and features that did not preclude pathology other than AD. Dr. Heath created a multifaceted treatment plan to address the inflammation in distinct areas of the body that included low-strength topical steroids for the face, stronger steroids for the body, and advice on scalp and skin care.
“I thought this was a great treatment plan out of the gate – I was covering all of the things on my differential list – I thought that the mom would be thinking, this doctor is amazing,” Dr. Heath said.
Pigmentary changes are a priority
However, that was not what the patient’s mother was thinking. Having failed to explicitly recognize her concern about the pigmentation changes and how the treatment would address this issue, the mother was disappointed.
“She had one question: Will my baby ever be one color? That was her main concern,” said Dr. Heath, indicating that other clinicians seeing inflammatory diseases in children with darker skin types can learn from her experience.
“Really, you have to acknowledge that the condition you are treating is causing the pigmentation change, and we do see that and that we have a treatment plan in place,” she said.
Because of differences in how inflammatory skin diseases present in darker skin types, there is plenty of room for a delayed diagnosis for clinicians who do not see many of these patients, according to Dr. Heath. Follicular eczema, which is common in skin of color, often presents with pruritus but differences in the appearance of the underlying disease can threaten a delay in diagnosis.
In cases of follicular eczema with itch in darker skin, the bumps look and feel like goose bumps, which “means that the eczema is really active and inflamed,” Dr. Heath said. When the skin becomes smooth and the itch dissipates, “you know that they are under great control.”
Psoriasis is often missed in children with darker skin types based on the misperception that it is rare. Although it is true that it is less common in Blacks than Whites, it is not rare, according to Dr. Heath. In inspecting the telltale erythematous plaque–like lesions, clinicians might start to consider alternative diagnoses when they do not detect the same erythematous appearance, but the reddish tone is often concealed in darker skin.
She said that predominant involvement in the head and neck and diaper area is often more common in children of color and that nail or scalp involvement, when present, is often a clue that psoriasis is the diagnosis.
Again, because many clinicians do not think immediately of psoriasis in darker skin children with lesions in the scalp, Dr. Heath advised this is another reason to include psoriasis in the differential diagnosis.
“If you have a child that has failed multiple courses of treatment for tinea capitis and they have well-demarcated plaques, it’s time to really start to think about pediatric psoriasis,” she said.
