SIMILAR TERMS--------------------------------------
Acne
Is a common inflammatory disease of the facial skin seen most frequently between the ages of 10 and 25 years and characterized by blackheads, whiteheads and blemishes composed of papules and pustules. Acne is an inflammatory disease of the sebaceous glands, the glands that produce sebum. Acne usually affects the face, back, and chest. In severe cases it can develop into cysts and nodules that can result in scarring. While its cause is unknown, it is most often associated with hormonal activity within teenagers. In severe cases a person should consult with a dermatologist for a specific acne treatment.

Acne mechanica

Acne rosacea
This term is actually a misnomer! The appropriate term is simply rosacea which is a chronic skin disease that affects the middle third of the face with persistent redness over the areas of the face and nose that normally blush: mainly the forehead, the chin and the lower half of the nose. The tiny blood vessels in these areas enlarge (dilate) and become more visible through the skin, appearing like tiny red lines (called telangiectasias). Pimples can occur that look like teenage acne. Unlike acne, rosacea is not primarily a plague of teenagers. It occurs most often in adults (ages 30 to 50), especially those with fair skin, and affects both sexes but tends to be more common in women but worse in men. Unlike acne, there are no blackheads or whiteheads in rosacea. When rosacea first develops, it may appear, then disappear, and then reappear. However, in time the skin fails to return to its normal color and the enlarged blood vessels and pimples arrive. Rosacea rarely reverses itself. It lasts for years and, untreated, it worsens. Untreated rosacea can cause a condition called rhinophyma (ryno-fee-ma), literally growth of the nose, characterized by a bulbous, enlarged red nose and puffy cheeks (like the old comedian W.C. Fields). There may also be thick bumps on the lower half of the nose and the nearby cheek areas. Rhinophyma occurs mainly in men.
