title: Sacrococcycygeal teratoma in adult: report of a case.
abstract: BACKGROUND
  Sacrococcygeal teratomas are neoplasias, which are most frequently found in infants, with the sacrococcígea area being the most frequently found extragonadal location.
  
  
  OBJECTIVE
  To describe a sacrococcygeal teratoma in a 51-year-old adult patient and discuss the diagnosis and management.
  
  
  METHODS
  The case of a 51-year-old woman who had a sacrococcygeal teratoma. Computed tomography showed a mass containing calcification. Early signs were when she experienced acute lower back pain upon leaning over or sitting.
  
  
  RESULTS
  The tumor appeared first as a sacral swelling. The patient also claimed disturbances in her bowel functioning. Computed tomography (CT) showed the tumor and its relationship inside the pelvic cavity. Surgical ablation was performed on the entire tumor and the coccyx was preserved.
  
  
  CONCLUSIONS
  The surgical block was sent to pathological exam, which showed it to be a mature sacrococcygeal teratoma. A good clinical evolution took place after resection.
