Lichenification is a rough, thickened, hardened area of epidermis resulting from chronic irritation such as scratching or rubbing. An example of lichenification is chronic dermatitis. A fissure is a linear crack with sharp edges, extending into the dermis. Examples include cracks at the corners of the mouth or in the hands, or those seen with athlete's foot. A keloid is an elevated, irregular, darkened area of excess scar tissue caused by excessive collagen formation during healing. It extends beyond the site of the original injury. An example of a keloid is scar tissue from ear piercing. Scales are shedding flakes of greasy, keratinized skin tissue. Examples of scales include dry skin, dandruff, psoriasis, and eczema.

Decreased oxygenation might cause nail thickening. Hemoglobin measures red blood cell oxygen-carrying capacity. If the patient has a hemoglobin problem, the nails would be spoon-shaped. A white blood cell count is used to check for an infection. The nails would appear to be inflamed or separating from the nail bed.
