A Case of Chronic Radiodermatitis following Radiofrequency Catheter Ablation for Atrial Fibrillation / 대한피부과학회지

Radiofrequency catheter ablation has been used for certain arrhythmic disorders for less than a decade, and has shown effectiveness in many cases. However, due to the complex nature of atrial fibrillation and high doses of ionizing radiation exposure during the procedure, radiofrequency catheter ablation has the possibility of inducing radiation damage. We herein describe one case of chronic radiodermatitis following radiofrequency catheter ablation for atrial fibrillation, a subject which has not been reported so far.

A Case of Chronic Radiodermatitis with CML and Squamous Cell Carcinoma in Radiologist

Chronic radiodermatitis may develop after repetitive exposure to small doses of ionizing radiation over an extensive period of time. Therefore, it is most likely to occur in people who work with ionizing radiation. The clinical symptoms of chronic radiodermatitis include atrophy, telangiectasia, sclerosis, pigmentary changes of the skin, ulceration and the development of malignancy. Cases of chronic radiodermatitis have occasionally been reported in physicians performing interventional procedures. Herein, we report a case of chronic radiodermatitis involving the 4th finger web and 5th finger of a radiologist, who suffered from chronic myelogenous leukemia shortly afterwards. The lesion on the 5th finger eventually progressed into squamous cell carcinoma.

Chronic Radiation Dermatitis Accompanied by Acrosclerosis and Loss of Digits due to Osteoradionecrosis / 대한피부과학회지

Chronic postirradiation changes of skin reflect the injury of dermal structures particularly the vasculature and connective tissue. The clinical signs include atrophy, partial or complete destruc tion of cutaneous appendatges, telangiectasis, sclerosis of underlying tissue, pigrnentary changes, and in rare instances, ulceration with or without var ious premalignant and malignant neoplasms. The patient, was a 65-year-old man, who had been exposed to a large amount. of X-ray irradi- ation on his hands incidentally or accidentally for a long time. The skin changes of his hand were thickening and hardening of all digits loss or focal consttict,ion of digits, and keratotic papules. Epidermal hyperplasia and fibrous thickening of collagen bundles were found on skin biopsy. Gradual narrowingal of the bony caliber with eventual resorption was noticed on radiologic examination. It has been rarely reported in the literature that chronic radiation dermatitis develops severe and unusal manifestions such as acrosclerosis and loss of digit due to osteoradionecrosis.
