Types of Eczema Keratosis

Put simply keratosis is a thickening of the skin. There are four basic
types of keratosis:

Actinic keratosis- which appears as rough, red or brown scaly patches
on the skin, is known as a precancerous condition because it sometimes
develops into squamous cell cancer. Like skin cancer, it usually appears
on sun-exposed areas but can be found elsewhere.

Seborrheic keratosis- is a thickening of the skin condition usually from
age, these areas can show a skin discoloration and may be mistaken
for malanoma.

Solar keratosis-are wart-like lumps from sun exposure. These also will
show a skin discoloration.

Keratosis pilaris-is a very common genetic follicular disease manifested
by the appearance of rough bumps on the skin. Primarily, it appears on
the back and outer sides of the upper arms, but can also occur on thighs
and buttocks or any body part except palms or soles. There are several
different types of keratosis pilaris, including keratosis pilaris rubra (red,
inflamed bumps), alba (rough, bumpy skin with no irritation), rubra faceii
(reddish rash on the cheeks) and related disorders.
