title: Focal cutaneous squamous cell carcinoma following radium-223 extravasation.
abstract: Long-term sequelae due to extravasation of intravenous radioisotopes resulting in radiation injuries are rarely reported. As the use of radioactive isotopes for the treatment of osteoblastic metastases increases, information regarding the prevention, treatment, and long-term monitoring of suspected extravasation injury will become increasingly important. We present a patient with no previous history of skin cancer who developed an aggressive cutaneous squamous cell carcinoma at the site of prior radium-223 extravasation. We recommend that patients who experience extravasation of therapeutic radioisotopes be monitored by dermatologists for long-term sequelae. Cutaneous squamous cell carcinoma should be recognized as a rare but potential adverse event following cutaneous extravasation of radium-223 and is likely a side effect that is severely underreported.
