Most Common Benign Skin Growths of Adulthood

Our skin develops various growths and changes that are normal as we mature. Many of these skin changes are benign and represent normal aging, sometimes due to intrinsic factors (i.e., genetics & natural age progression changes) and/or extrinsic factors (i.e., sun exposure). The purpose of this article is to provide you with basic background information for better understanding. It is important to have a qualified skin expert (Board-certified Dermatologists) confirm these growths are benign (non-cancerous) and not malignant (cancerous).

Benign skin growths do not require removal or treatment. Many people desire to have them removed, and there are various techniques often yielding excellent cosmetic outcomes. The procedures are almost always a non-covered benefit of medical insurance.

 

 

SOLAR LENTIGO (also known as SUN SPOT, LIVER SPOT)
A solar lentigo (lentigines, plural) is a tan, brown or dark brown flat discoloration of the skin usually 2 mm to 2 cm in size, most commonly appearing on sun-exposed areas of the body, including the face, neck, chest, shoulders, arms, hands, and legs. They represent excess pigmentation in the skin caused by ultraviolet light exposure over time.

They do not require treatment; however, intense pulsed light and/or fractional resurfacing lasers with some topical therapies yield excellent results.

SEBORRHEIC KERATOSIS (also known as Warty Keratosis, Stucco Keratosis, Barnacles)
Seborrheic keratoses are benign skin growths of the outer layer of skin (epidermis), often described as “waxy”, “stuck-on”, “warty”, or “barnacles.” They may be few or numerous in number. The color is often brown, but can be skin-colored or black. They can appear on almost any part of the body including the face, scalp, torso, extremities, and genitals. Seborrheic keratoses may exhibit more than one color and grow quickly, prompting patients to visit the Dermatologist.

Seborrheic keratoses can be successfully removed using a variety of techniques, including cryotherapy, electrodessication, surgery, and/or laser.

FIBROUS PAPULE (also known as ANGIOFIBROMA)
Benign growth composed of collagen fibrous tissue and blood vessels. They range from white-skin colored to red, often with a smooth surface appearance. They occurs most commonly on the face, particularly on the tip or side of the nose;

Cosmetic shave contouring, electrocautery (electric heated needle tip) and/or laser treatments can successfully remove these growths.

HEMANGIOMA (also known as CHERRY ANGIOMA)
Adult onset hemangiomas are benign clusters of dilated blood vessels. They range from bright red to purple, often with a smooth surface appearance. They occurs most commonly on the torso; however, a hemangioma can develop anywhere on the body. Individuals may develop a few to hundreds of them.

Electrocautery (electric heated needle tip) or laser treatments can successfully remove these spots.

SKIN TAGS (ACROCORDONS)
Skin tags are soft benign skin growths that hang off the skin surface. They are often skin-colored but can appear pink, tan, or brown. They most commonly form in areas of friction, such as the neck, armpits, and groin. They are relatively frequent around the eyelids as well.

Skin tags can be successfully treated using snip removal, electrodessication, and/or cryosurgery.

SEBACEOUS HYPERPLASIA
Sebaceous hyperplasia growths are smooth or waxy, small white or yellow bumps on the face commonly mistaken for whitehead pimples. They are frequently unsuccessfully extracted during facials. These benign growths are enlarged clusters of normal oil glands in the skin, most commonly appearing in the 3rd or 4th decade of life and can increase in number and size over time.

Sebaceous hyperplasia can be successfully removed using electrodessication and/or laser.

DERMATOFIBROMA
Dermatofibromas are often solitary growths that appear over a few weeks. The color can range from pink-red, to brown often shaped in a dome and firm to the touch. They can sometimes exhibit a feature called the “dimple sign” where the growth dimples into the skin when pinched. They occur most commonly on the legs of women, but also on the arms & shoulders of both men and women. Dermatofibromas represent a scar-like reactive process that may be induced by a trauma, such as an insect bite. They often grow to a certain size and stay.

They can be removed surgically.

EPIDERMAL INCLUSION CYST (also known as SEBACEOUS CYST, FOLLICULAR HAIR CYST)
An epidermal inclusion cyst is a benign growth composed of an incomplete hair follicle-oil gland lining, filled with keratin. The produced keratin becomes compact into a cheese-like material. They sometimes have a small opening from which the malodorous keratin can be expressed or no surface opening, which appears as a smooth bump underneath the skin surface. They often grow to a certain size then stay. If the cyst lining ruptures, a boil or abscess can form.

Surgery is the preferred technique for removing cysts.

MILIA
Milia can be thought of as miniature epidermoid cysts. They frequently occur around the eyelids of young women, but can appear  on other parts of the face and body on  men or women.

Milia can be effectively removed using extraction, electrodessication, and/or laser.

LIPOMA
A lipoma is a benign fatty tumor that lies deep in the skin and appears as a soft lump. Occasionally, lipomas are tender to the touch but usually do not cause other symptoms. Lipomas may be small or quite large and develop in adults as single or multiple lesions, sometimes hereditary.

Surgery or liposuction yield excellent results.
