title: Dermoscopy of multiple radiation-induced basal cell carcinomas in a patient treated previously for pinealoma.
abstract: BACKGROUND
  Malignancies secondary to radiation, such as radiation-induced skin cancer, are possible consequences of radiation therapy. The most frequent post-radiation skin neoplasm is basal cell carcinoma.
  
  
  METHODS
  We report a case of a 49-year-old woman who underwent multiple radiotherapy sessions for pinealoma and developed post-radiation alopecia. After 26 years the patient noticed the emergence of eighteen superficial scalp lesions in the previously irradiated areas. Dermoscopy showed predominance of ovoid nests and presence of arborizing vessels on pink background, consistent with basal cells carcinoma. The diagnosis was confirmed by histopathology.
  
  
  CONCLUSIONS
  There is an absolute need to guide patients through the possible late adverse events of radiotherapy. Regular dermoscopy examinations should be performed, especially in areas previously exposed to radiation.
