BEAUTY TIPS

The skin is subject to various problems - blemishes, infections and growth due to internal or external causes. Some of the skin disorders are

It occurs equally among men and women

Lesion - Change in tissue formation.

Lesion: Pronounced "lee-sion" with the emphasis on the "lee," a lesion can be almost any abnormality involving any tissue or organ due to any disease or any injury.

There are, not surprisingly, many types of lesions. There are also a number of different ways of classifying and naming lesions. Lesions can, for instance, be categorized according to whether or not they are caused by cancer. A benign lesion is non-cancerous whereas a malignant lesion is cancerous. For example, a biopsy of a skin lesion may prove it to be benign or malignant, or evolving into a malignant lesion (called a premalignant lesion).

Lesions can be defined according to the patterns they form. For example, a bull's-eye or target lesion is one that looks like the bull's eye on a target. (In an X-ray of the duodenum, a bull's-eye lesion can represent a tumor with an ulcer (crater) in the center.) A coin lesion is a round shadow resembling a coin on a chest X-ray. It, too, is usually due to a tumor.

Lesions can be named for persons who first described them. For instance, a Ghon lesion (or Ghon focus) is the scar-like "signature" in the lungs of adults left by tuberculosis in childhood.

Lesions can also be categorized by their size. A gross lesion is one that can be seen with the naked eye. A microscopic or histologic lesion requires the magnification of a microscope to be seen. The basis of sickle cell disease is a molecular lesion, one that is not even visible with a microscope but is only detectable on the molecular (protein or DNA) level.

Location is another basis for naming lesions. In neurology, a central lesion involves the brain or spinal cord, i.e., the central nervous system. A peripheral lesion involves the nerves away from the spinal cord and does not involve the central nervous system.

There is a virtually endless assortment of lesions in medicine: primary lesions, secondary lesions, impaction lesions, indiscriminate lesions, irritative lesions, etc. Many are named for people including the Armanni-Ebstein lesion, a Bankart lesion, a Blumenthal lesion, and so on.

The word "lesion" comes from the Latin noun "laesio" meaning "an attack or injury" which is related in Latin to the verb "laedere" = "to hurt, strike or wound."

Papule - A firm raised lesion

Pustule - Similar to papule but contains puss.

Seborrhea - Excessive secretion of disturbed quantity of sebum is collected upon the skin in the form of oily coating. This is known as seborrhea. Some times a burning sensation is felt

White heads - These are caused by pores getting clogged with hardened oil. Here the pores are not open. They therefore show up as tiny white pearly lumps beneath the surface of the skin. They usually form on oily skin.

Black heads - In this case the pores are open and clogged sebum is exposed to the air. Oxidation takes place turning it black in colour.

Acne - This is one of the most common skin disorders which primarily affects the adolescents as it can be caused by increase of sex hormones which takes place during puberty. This imbalance of sex hormones causes the sebaceous glands to secrete more sebum (Sebum is a semi-fluid oily substance which lubricates the skin). The pores of the skin enlarge and get blocked with hardened sebum. This result in black heads and pimples. Some of these develop into pustule which rupture and spread infection. Both men and women are affected by acne, but young men are more likely to have more severe, longer lasting forms of acne.

Acne should never be neglected as it causes extensive scarring. Clinical and professional treatment is necessary.
