Seborrheic dermatitis is one of the most common skin conditions associated with HIV infection, affecting more than 80% of people with advanced stages of the disease. However, it is not uncommon for people with mild immunosuppression to develop this type of rash when the CD4 count is below 500 .
Seborrheic dermatitis is an inflammatory skin disorder that usually affects the scalp, face, and trunk. It often appears in oilier areas of the skin and presents with mild redness, yellow peeling, and scaly skin lesions.
In more severe cases, it can cause scaly pimples around the face and behind the ears, as well as on the nose, eyebrows, chest, upper back, armpits, and inside of the ear. The causes of the rash are not fully understood, although a decrease in immune function is undoubtedly a key factor.
In more severe cases, topical corticosteroids can help. People with HIV who are not yet on treatment should receive antiretroviral therapy immediately to help maintain or restore immune function.
