Colour of lumps may vary from pinkish white to brownish black.Size of lumps may vary from 1-2 mm on the eyelids to 1-2 cm on the trunk.Formation of tiny to large elevated lumps on the skin, usually with a pointed tip.They are usually manifested through the following symptoms.
Skin tags are basically benign tumors made up of fibrous connective tissues.
Abnormally high levels of cholesterol (LDL cholesterol). Overactivation of the mast cells and tumor necrosis factor. Abnormalities in carbohydrate and lipid metabolism. Reduced glucose tolerance and insulin resistance. Existing tumors of the gastrointestinal tract and kidneys which cause the release of skin factors that lead to skin outgrowths and skin tags. 
Autosomal dominant disorders such as Birt-Hugg-Dube syndrome, that are manifested as benign tumor outgrowths of hair follicles such as in fibrofolliculoma or trichodiscoma conditions.
Epidermal growth factor and alpha tissue growth factor. Hormonal fluctuations especially elevated estrogen and progesterone level during pregnancy or increased growth hormone (somatotropin) in few medical conditions such as Acromegaly. Irritation and frequent friction in few parts of the skin (such as underarms, thighs, breasts and in some cases the genitals). Degeneration of skin cells due to aging. Research findings have revealed that the following factors may increase possibilities of skin tags in aged people or even in young adults. What causes skin tags?Ī skin tag may or may not arise due to specific etiological factors. In some instances, skin tags have also been observed in young people. Skin tags are not indicators of diseases or associated complications. In numerous cases, the skin tag detaches and falls off from the skin surface due to lack of blood supply (due to irritation caused by rough clothing, jewelry etc). Recent studies have revealed that skin tag forms on those parts of the body that are subjected to frequent friction such as armpits, the inner portion of thighs, eyelids, breasts etc. But in a few cases, it might be larger in size. A skin tag typically varies from 1 to 5 mm in length. They appear to be loosely attached to the skin surface by a narrow stalk. These are essentially normal outgrowths of the skin and may be pigmented or non-pigmented. Extensive research has revealed that these tags are closely linked to Diabetes, Insulin resistance, senility or obesity or few metabolic syndromes. They are usually manifested as soft, pedunculated (comprising of an elongated stalk of tissue), brownish or flesh-colored skin tumor (benign) that hang from the eyelids, neck or the armpit. Skin tags medically termed as “acrochordons” are benign outgrowths of the skin that are found in elderly people and are often mistaken for moles or other skin outgrowths. 
But the effectiveness of such techniques has not been verified in several cases. Numerous techniques for removal of skin tags are recommended by dermatologists. But in most cases, they have been found to be completely benign and do not interfere with healthy living. At present, there is a lot of controversy regarding whether skin tags are indicators of skin cancer or not. These tags are normally formed as portions of the existing skin and do not cause any harmful effects. Skin tags are a very common occurrence in aged people and are more prevalent in elderly men, especially the ones above 65. The most common among these are warts, moles, freckles and skin tags. Aging is associated with several skin ailments which are in many cases benign.
