Thickening of the skin can be termed as keratosis. It resembles an overgrowth restricted to a particular area on the upper layer of the skin resembling a wart or callus.
Actinic keratosis / solar keratosis: Thick brittle and scaly patches in the skin that indicate pre malignancy, actinic keratosis indicates the progress of skin cancer. This condition is commonly referred to as precancerous condition. This condition is common among white skinned people and in people aged above 30. People diagnosed with this condition should visit the doctor on a regular basis to keep a track on these bumps. Constant exposure to sun can cause this condition. It is common in the exposed areas of the body such as chest, forearms, ears, neck, backs of hands, face, scalp and lips. Symptoms include scaly patches, rashes that don't itch or pain and reddish-brown skin. Actinic keratosis is treated through surgery. If the bumps are large, laser surgery is performed, for smaller bumps cryotherapy is performed.
Seborrheic keratosis: Small pink and brown warts represent seborrheic keratosis, this type of keratosis is benign. They resemble age spots and appear with aging. The exact cause for this condition is clearly not known. The growth occurs in areas that are more often exposed to the sun. Genetic reasons could also cause this condition. It is characterized by yellow-brown warts or papules. Seborrheic keratosis requires no treatment as it is harmless but picking at the spot might lead to an infection. In case the person affected by the condition prefers removal of these growths, they can be removed through cryotherapy, electrocautery (burning the growth with electric current) and curettage (scraping off the surface of the skin using specialized instruments).
Keratosis pilaris: Red bumps on the skin indicate keratosis pilaris, the skin surface also gets rough and bumpy. It is commonly referred to as chicken skin. This type of keratosis is usually mistaken for pimples. Keratosis pilaris is more common in children and settles down on its own as they grow up. Excessive keratin produced in the human body causes this condition. This condition is also believed to be hereditary. This condition appears like rough bumps on the skin that might get itchy. There is no treatment for keratosis pilaris. Exfoliation and moisturizing the affected area can make the skin soft and smooth.
Electrosurgery is a surgical procedure where high-frequency electric current is used to cut, coagulate tissue or remove lesions. Typically electrosurgery is suited for dermatological conditions such as warts, benign skin tumors, Seborroeic keratosis and skin tags. With limited blood loss, electrosurgery allows precision cuts so as to burn tissue and fulgurate it. While it is not very painful for small lesions, local anaesthesia is used for larger lesions. Electrosurgery is an alternative to laser surgery and cryosurgery.
