Haemangiosarcoma following irradiation of a haemangioma of the face. (Case report).
The malignant complications of irradiating benign conditions are well known and fortunately less frequent than in a previous era of widespread use of superficial roentgen therapy. However, because of the long latent period from exposure to irradiation until the development of the tumour, the clinician must continue to be alert. The behaviour and treatment of a haemangiosarcoma occurring 18 years after irradiation of a haemangioma is described.
