title: [Bone changes following long-term isotretinoin (Roaccutane) treatment].
abstract: The case is presented of a 33-year-old man treated with Roaccutane for two years on account of severe acne conglobata. X-ray examination after two years showed pronounced hyperostoses with bridging in the thoracic spine and hyperostoses and beginning bridging in the cervical spine. Furthermore, small exostoses were found on the hands and feet. X-ray control of patients treated for more than six months with Roaccutane is recommended.
