7. A Dark, Velvety Neck Rash
A dark, velvety rash along the folds of your neck may be a condition called acanthosis nigricans. In addition to the folds of the neck, this rash may also appear in your armpits or groin area. Risk factors for this rash include obesity and a family history of acanthosis nigricans. The Mayo Clinic lists diabetes, ovarian cysts, and thyroid disorders as possible causes of this rash. Additionally, certain drugs such as niacin, hormone medications, and corticosteroids can cause this condition. Furthermore, cancers such as lymphoma or certain tumors may cause acanthosis nigricans.
6. Dimpled or Pitted Skin
Skin that appears dimpled or pitted may indicate an underlying medical condition. In some cases, the skin may take on an appearance similar to the texture of an orange peel. Such pitting of breast tissue may indicate inflammatory breast cancer, according to the National Cancer Institute. A skin infection, such as cellulitis, is another possible reason for skin pitting to occur. Furthermore, pitting or dimpling of the skin due to swelling may be a symptom of diabetes. Contact your physician if you notice unexplained furrows or dimples in your skin.
5. Unexplained Bruising
Bumps and bruises are usually linked to memorable, clumsy mishaps. However, excessive or unexplained bruising may be a sign of something more serious. Leukemia is a condition in which the body produces excessive amounts of immature white blood cells. Then, in turn, the body is unable to produce enough healthy red blood cells. According to the American Cancer Society, shortages of red blood cells can cause weakness, fatigue, frequent infections, bleeding, and bruising. Other symptoms of acute lymphocytic leukemia may include weight loss, fever, night sweating, and a decreased appetite.
