Kim, Kim, Shin, Hong, Lee, Park, Hwang, and Rim: Fluoroscopy-induced Subacute Radiation Dermatitis in Patient with Hepatocellular Carcinoma

Abstract

Radiation dermatitis can develop after fluoroscopy-guided interventional procedures. Cases of fluoroscopy-induced radiation dermatitis have been reported since 1996, mostly documented in the fields of radiology, cardiology and dermatology. Since diagnosis and treatment of fluoroscopy-induced radiation dermatitis can be difficult, high grade of suspicion is required. The extent of this reaction is determined by radiation dose, duration of exposure, type of procedure, and host factors and can be aggravated by concomitant use of photosensitizers. Follow-up is important after long and complicated procedures and efforts to minimize radiation exposure time will be necessary to prevent radiation dermatitis. Herein, we report a case of a 58-year-old man with hepatocellular carcinoma presenting with subacute radiation dermatitis after prolonged fluoroscopic exposure during transarterial chemoembolization and chemoport insertion. Physicians should be aware that fluoroscopy is a potential cause of radiation dermatitis.

Fig. 1.
(A) One day after radiation therapy, the lesion is described as a relatively sharply demarcated, erythematous, square shaped patch with erosion and moist desquamation. (B) One month later, re-epithelialization is starting from the margin and a pinkish plaque is present. (C) Two month later, the entire lesion is almost healed and re-epithelialized.

Microscopic findings (H&E). (A) A dermal-epidermal separation and a mild inflammatory infiltrate involving the epidermis, papillary dermis, and vessels is seen (×40). (B) High-power field showed a atrophic change of the epidermis with scattered atypical keratinocytes, hyperkeratosis, and spongiosis (×100).
