title: Oral primary angiosarcoma of the lower lip mucosa: report of a case in a 15-year-old boy.
abstract: BACKGROUND
  Angiosarcomas are rare soft tissue malignant tumors with dismal prognosis. Head and neck involvement is uncommon (5%) and usually affects the scalp or facial skin.
  
  
  RESULTS
  We present the case of an inferior lip mucosal low-grade angiosarcoma in a 15-year-old boy treated exclusively with surgery. One and a half years after treatment, the patient was free of signs of recurrence. Prompt and accurate diagnosis with adequate imaging modalities and multidisciplinary treatment are crucial for optimal management of these neoplasms.
  
  
  CONCLUSIONS
  Lip mucosal involvement is exceptional with only a few cases described in the literature, all in patients older than 60 years To our knowledge, this is the youngest patient ever reported.
