A dysplastic nevus is an atypical mole; a mole whose appearance is different from that of common moles. About one out of every ten people has at least one unusual (or atypical) mole that looks different from an ordinary mole. Doctors believe that dysplastic nevi are more likely than ordinary moles to develop into a type of skin cancer called melanoma.

Rosacea is a skin conditon that most often appears in the middle of your face - typically cheeks, nose, and chin - and makes your face look red or flushed. You may sometimes get bumps or pimples in the same area. The redness, flushing, and bumps often come and go. As many as 14 million Americans have rosacea.

Eczema is a group of conditions that causes skin to become red, irritated, itchy, and sometimes develop small, fluid-filled bumps that become moist and ooze. There are many forms of eczema, but atopic eczema is one of the most common. Doctors don't know exactly what causes atopic eczema, also called atopic dermatitis (pronounced: der-muh-tie-tis), but they think it could be a difference in the way a person's immune system reacts to things. Skin allergies may be involved in some forms of eczema. Eczema isn't contagious and most people with eczema have family members with the condition.

It is a chronic skin condition that usually is characterized by lesions or patches of raised red skin covered by flaky, silvery-white buildup called "scales" or "plaques." The red-wine or salmon-colored patches are often rough to touch. There are several different types of psoriasis. It is usually mild with a few scales, but it can be much more severe.
