What kind of doctor treats Fox-Fordyce Disease?
A dermatologist, a doctor who treats skin conditions, is the specialist usually recommended for Fox-Fordyce Disease. A dermatopathologist, a doctor who studies skin samples under a microscope, may read a skin biopsy. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Fox-Fordyce disease?
Fox-Fordyce disease is a rare skin disorder that mainly affects women. It causes intense itching, especially in the underarm area, the pubic area, and around the nipples.
The disease involves the apocrine glands, a type of sweat gland. Most apocrine glands are in the armpits or the groin. In Fox-Fordyce disease, problems with these glands cause inflammation, enlargement of the glands, and itching. It is also called apocrine miliaria.
Symptoms
Symptoms may appear suddenly, often after heat, humidity, or friction. Signs include:
- Many small, raised bumps (papules) on the skin near the apocrine glands, most often in the armpits.
- Bumps that are usually skin-colored, dome-shaped, and smooth, but may be yellowish or reddish.
- Itching that can be mild or strong enough to disturb sleep.
- Sweating in the affected area may be absent.
- Hair loss in the affected area.
- Skin near the area that may become darker and dry.
Causes and who gets it
The exact cause of Fox-Fordyce disease is unknown. Some researchers think blocked apocrine gland ducts, the tiny tubes that carry sweat out, are needed for the disease. Studies have not been able to confirm this theory. Hormones or genes may also play a role, but research has not given a clear answer.
The disease occurs mainly in women between 13 and 35 years old. In rare cases, it can affect men, children, and women after menopause. Heat, humidity, stress, and exercise can make it worse. It may be more severe during menstruation and tends to disappear during pregnancy.
How doctors diagnose it
Doctors diagnose it from its typical signs, your health history, and an exam. A biopsy, where a small piece of skin is removed and checked under a microscope, may help. Biopsy results can vary and are not specific, so the diagnosis mostly relies on the exam.
Other skin problems can have similar symptoms. Two examples are heat rash and hidradenitis suppurativa, a long-term skin disease with boil-like lumps. Doctors compare them to be sure.
Treatment
Treatment is aimed at the symptoms each person has, and seeing a dermatologist is recommended. Doctors have used estrogen hormones, oral retinoids (pills related to vitamin A), and steroid creams. They have also used topical antibiotics, which are put on the skin.
Estrogen, usually given in estrogen-based birth control pills, has been the most effective for women. Retinoids, steroid creams, and topical antibiotics have helped some people and not others. Some of these treatments can irritate the skin, which can limit long-term use. No therapy works for everyone. Doctors have also tried lasers. Ask your doctor about the risks of each medicine.
Some women see a major improvement or clearing of the disease during pregnancy.
When to see a doctor
See a doctor if you have itchy bumps that do not go away. Common spots are the armpits, groin, and nipples. Also see a doctor if itching keeps you up at night. A doctor can check for other skin problems that can look similar.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can do a first evaluation, follow your progress, and refer you to a dermatologist.
