Benign skin lesions basically refer to skin disorders characterised by pouches or closed pockets of tissue which are filled with water or some other fluids. They tend to feel like pea shaped structures which can roll under the skin and feel smooth when pressure is applied on them.
These lesions can develop due to any kind of microbial infection or any other kind of obstruction in the sebaceous glands and generally manifest themselves as warts or moles in the body.
The causes of these kinds of lesions depend on the age group of the individual along with the ethnicity and the degree of exposure to the sun.
There are basically two kinds of skin lesions. One group is referred to as discrete lesions while the other form of the anomalies is referred to as rashes. The lesions can be further subdivided into three categories depending on whether they appear above or below the outer layer of the skin. If the lesions appear below the skin they are called sub-epidermal lesions or papular lesions, while the lesions which appear to be raised or flat are called macular lesions or plaque.
Benign skin lesions can also be distinguished from others in terms of their color or pigmentation. There are usually three kinds of lesions which can be differentiated, based on their color. They are near-flesh colored lesions, red vascular-appearing lesions or pigmented lesions.
The treatment procedure for lesions usually involves carrying out a surgical procedure in order to remove the lesion. Initially, a biopsy is done to find out whether the lesion is benign or malignant. In case of a benign lesion a minor surgery in order to remove the lesion is enough. Several other techniques like cryosurgery may also be performed for treatment of benign skin lesions.
