A Red Rash on Your Torso, Extremities, or Face

If you haven’t seen the sun in months, but your arms, legs, and torso still look burned, it could be a sign of scarlet fever.

Keeping yourself safe from skin cancer starts with the ABCDEs. If you have an asymmetrical mole, one with an irregular border, one that’s a variety of colors, one that’s got a diameter larger than a pencil eraser, or one that’s evolving from its original state, you may have melanoma. Make sure you check in with your doctor at least once a year for a full-body scan.

Itchiness

Everything from wool sweaters to winter weather can make your skin itchy, but sometimes, there’s a more serious underlying cause to that uncomfortable itch.

14
Pitted Skin

If you’ve noticed that the skin around your breasts has developed a pitted appearance, it’s time to get to the doctor. Sudden dimpling of the skin on or around the breasts, also known as peau d’orange, can be a sign of breast cancer.

Yellow skin

15
Yellowing of Skin

That yellowish tint to your skin may be more than just a spray tan gone wrong. In many cases, when your skin has adopted a yellow hue, it’s a symptom of jaundice, or an excess of bilirubin, a waste product created by the breakdown of hemoglobin, in your bloodstream.

Scaly patch psoriasis

16
Patchy Discoloration

Patchy discoloration on your skin definitely merits a mention to your doctor. This is often a sign of psoriasis, which, while generally more annoying than dangerous, can lead to arthritic joint pain, skin infections, and in the case of complications or erythrodermic psoriasis, even death.

Hives on arm

Hives
