What does psoriasis look like? What are psoriasis symptoms and signs? (Continued)
Sometimes pulling off one of these small dry white flakes of skin causes a tiny blood spot on the skin. This is medically referred to as a special diagnostic sign in psoriasis called the Auspitz sign.
Genital lesions, especially on the head of the penis, are common. Psoriasis in moist areas like the navel or the area between the buttocks (intergluteal folds) may look like flat red patches. These atypical appearances may be confused with other skin conditions like fungal infections, yeast infections, skin irritation, or bacterial infections.
Finger and toenails often exhibit small pits (pinpoint depressions) and/or larger yellowish-brown separations of the nail bed called "oil spots." Nail psoriasis may be confused with and incorrectly diagnosed as a fungal nail infection.
Scalp psoriasis may look like severe dandruff with dry flakes and red areas of skin. It may be difficult to differentiate between scalp psoriasis and seborrhea dermatitis when only the scalp is involved. However, the treatment is often very similar for both conditions.
