We reported a case of radiation-induced squamous cell carcinoma on the bilateral middle finger of an 87-year-old physician.He had exposed his hands to radiation without defense when he took an X-ray photograph. Squamous papules and ulcers occurred on both of his hands 10-years ago. The ulcer on the right middle finger enlarged rapidly after a one-month duration. A biopsy specimen showing squamous cell carcinoma derived from chronic radiation dermatitis, and disarticulation at the PIP joint of the right middle finger was performed. Six month later, hyperkeratotic tumor newly occurred on the opposite middle finger, and were operated on in the same way. The remaining lesions of chronic radiation dermatitis were treated by topical bleomycin hydrochloride. Since medical workers carelessly exposed their skin to radiation several decades ago, attention to late occurrence of radiation-induced skin cancer is needed. [Skin Cancer (Japan) 2004; 19: 336-339]
