Skin Lesions And Cysts

OVERVIEW

A skin lesion is a superficial growth or patch of the skin that does not resemble the area surrounding it. Skin lesions may be present at birth (like moles or birthmarks) or may be acquired during a person’s lifetime due to environmental agents like sunburn or extreme weather. Also, over time our skin changes and may develop skin marks such as freckles and moles, which may multiply or darken over time.

THE SOLUTION

Cysts and skin lesions can be removed under local anesthesia at any of our centers with the minimum of discomfort. The treatment varies depending on the growth:

Dermatofibromas

Small, firm, red or brown bumps caused by an accumulation of fibroblasts (soft tissue cells under the skin). They often occur on the legs and may itch. Dermato-fibromas can be surgically removed if they become painful or itchy.

Dermoid cyst

A benign tumor which is made up of hair, sweat glands and sebaceous glands. Some internal dermoid tumors may even contain cartilage, bone fragments and teeth. This type of cyst may be removed surgically for cosmetic reasons.

Keloids

Smooth, firm, raised, fibrous growths on the skin that form in wound sites. Keloids are more common on darker skins. Keloids respond poorly to most treatment approaches. Injections of corticosteroid drugs may help to flatten the keloids. Other treatment approaches may include surgery or silicone patches to further flatten the keloids.

Keratoacanthomas

A round, flesh-colored growth that has a crater which contains a pasty material. These growths tend to appear on the face, forearm or back of the hand. They usually disappear after a couple of months but may leave scars. Treatment usually includes a skin biopsy to rule out skin cancer and may include surgical removal and/or injections of corticosteroids or fluorouracil.

Lipomas

Round or oval lumps under the skin caused by fatty deposits. Lipomas are more common in women and tend to appear on the forearms, torso, and back of the neck. Lipomas are generally harmless, but if they change shape, the physician may perform a biopsy. Treatment may include removal by surgery.

Moles (nevi)*

Small skin marks caused by pigment-producing cells in the skin. Moles can be flat or raised, smooth or rough, and some may contain hair. Most moles are dark brown or black, but some are skin-colored or yellowish. Moles can change over time and often respond to hormonal changes. Most moles are benign, and no treatment is necessary. Some benign moles can develop into skin cancer (melanoma).

Atypical moles (dysplastic nevi)

They are larger (more than a half inch across), than normal moles atypical moles are not always round. Atypical moles can be tan to dark brown, on a pink background. These types of moles may occur anywhere on the body.

Treatment may include removal of any atypical mole that changes in color, shape and/or size. People with atypical moles should avoid sun exposure, since sunlight may accelerate changes. A physician should be consulted if any changes occur.

Pyogenic granulomas

Red, brown, or bluish-black raised marks caused by excessive growth of capillaries (small blood vessels) and swelling. Pyogenic granulomas usually form after an injury to the skin.
Some pyogenic granulomas disappear without treatment. Sometimes, a biopsy is necessary to rule out cancer. Treatment may include surgical removal.

Seborrheic keratoses

Flesh-colored, brown, or black wart-like spots. More common in middle-aged and older people, seborrheic keratoses may be round or oval and look like they are “stuck” on the skin. Usually, no treatment is necessary. If the spots are irritated, or the patient wants them removed for cosmetic reasons, treatment may include freezing the area with liquid nitrogen or surgery.

Skin tags

Soft, small, flesh-colored skin flaps on the neck, armpits, or groin. If the skin tags are irritated, or the patient wants them removed for cosmetic reasons, treatment may include freezing the tags with liquid nitrogen or surgery.
