Acanthosis nigricans

Adrenal insufficiency

The adrenal gland's outer layer produces hormones such as cortisol and aldosterone, which control many important functions of the body such as blood sugar and blood pressure regulation, and urine production. In adrenal insufficiency, not enough of these hormones are produced, leading to symptoms such as fatigue and weakness, appetite and weight loss, nausea, and vomiting.

Rarity: Ultra rare

Top Symptoms: depressed mood, anxiety, abdominal pain (stomach ache), loss of appetite, nausea or vomiting

Folate (vitamin) deficiency

Folate is also called folic acid or vitamin B9. It is needed to create red blood cells, which carry oxygen throughout the body. A shortage of folate leads to a shortage of healthy red blood cells, which is also called anemia.

Folate deficiency can be caused by poor diet; alcohol use; some medications; diseases of the large intestine; and pregnancy, since the growing baby requires folate in larger amounts.

Symptoms include severe fatigue; loss of appetite; diarrhea; paleness; sore tongue; and irritability. The same symptoms can appear in other conditions, especially blood disorders.

Folate deficiency is also a cause of abnormal brain and spine development in a fetus. For these reasons, it is very important to see a medical provider if these symptoms occur.

Diagnosis is made through patient history, physical examination, blood tests, and sometimes digestive tract studies.

Treatment involves immediate supplementation of folate with injections, followed by folate and other vitamin and mineral tablets; improvement in diet; and treating any underlying digestive or blood disorder.

Rarity: Rare

Top Symptoms: fatigue, depressed mood, irritability, nausea or vomiting, diarrhea

Symptoms that never occur with folate (vitamin) deficiency: abdominal swelling

Urgency: Phone call or in-person visit

Skin tag

A cutaneous skin tag is a common skin growth. It is small and benign and can occur anywhere on the body, but especially in places where the body folds (armpits, neck, groin, etc).

Rarity: Common

Top Symptoms: rash, skin-colored rash, lump darker than surrounding skin, skin bump that looks like it has a stalk

Urgency: Wait and watch

Benign skin growth

Benign skin growths are very common and virtually everyone has some form of them. "Benign" means the growth is not cancerous and not harmful. Some of these growths have genetic origins, and for some the cause is not clear.

Common types are:

  • Birthmarks – may appear as flat "stains" in the skin or as raised clusters formed of tiny blood vessels.
  • Moles – small irregularities that originate in the pigment-producing cells in the skin. They can be almost any shape or color but are normally no larger than one-quarter of an inch across.
  • Skin tags – little irregular flaps of skin, like a flattened mole attached on only one side.
  • Keloids – a dark, fibrous form of scar tissue that forms after a skin wound, either from trauma or from surgery.

As a person ages, more changes may appear in the skin. Most are benign, but any unusual or suspicious skin growth should be checked by a medical provider. The growth can be removed if it is unsightly, interferes with clothing, or proves to be malignant (cancerous.)

Rarity: Common

Top Symptoms: constant skin changes, itchy rash, rash with well-defined border, abdominal skin changes, neck skin changes

Symptoms that always occur with benign skin growth: constant skin changes

Symptoms that never occur with benign skin growth: cherry red lower leg bump

Urgency: Wait and watch
