Radiation Dermatitis

Radiation dermatitis is defined as skin changes resulting from exposure to ionizing radiation. There are reversible effects, i.e., erythema, epilation, suppression of sebaceous glands, and pigmentation that lasts for weeks to months to years, and irreversible effects, i.e., acute and chronic radiation dermatitis and radiation-induced cancers.


* High exposure to radiation can cause significant damage to the skin (radiodermatitis).
* Small blood vessels (capillaries) break down, resulting in changes in the color of the skin.
* Neoplastic transformation develops in the ulcers or the keratoses.


The skin becomes dry, fine, and hairless due to atrophy of the epidermis, and is easily vulnerable to minor trauma.

Hyperkeratotic plaques and painful keratoses form on the sides of the fingers and fingertips
