Dirt-like spots on your neck
A neck rash resembling dirt could be acanthosis nigricans rash. It may be a sign that a patient has diabetes or insulin resistance, according to Dr. Lipner. This rash might be thanks to an underlying endocrine problem such as thyroid disease, polycystic ovarian syndrome, or an adrenal problem, Dr. Lipner adds. Plus, in rare cases, it could be a presenting sign of underlying cancer in the stomach, colon, or liver. “It is also more common in obese people and may run in families,” Dr. Lipner says. “It is important to see a board-certified dermatologist who can make the diagnosis and work up the patient for underlying disorders.” Still, this rash might be because of medications like birth control or niacin, but it’s still a good idea to check with your doctor.
