title: [Adult paratesticular sarcomas. Management and evolution of the disease].
abstract: OBJECTIVE
  Identify and analyze the clinic pathologic characteristics, therapeutic, and the evolution of the disease in adult patients with a diagnosis of paratesticular sarcoma.
  
  
  METHODS
  We reviewed retrospectively the medical records of patients diagnosed with sarcoma paratesticular location of the department of urology at the National Institute of Neoplastic Diseases from 1952 to 2003. Data was collected affiliation, background, symptoms, diagnostic methods, pathological diagnosis, treatment and status of the disease. We analyzed statistically evaluated and compared with information obtained in the literature.
  
  
  RESULTS
  Sixteen paratesticular sarcomas cases were found in patients greater than 16 years old; 9 rhabdomyosarcomas, 3 leiomyosarcomas, 3 liposarcomas, and 1 nonclassifiable sarcoma. There were two thresholds of presentation, one among 16 to 20 years and another one in greater than 60 years. Six had metastatic disease at diagnosis. The average survival was 32.18 months with a range among 1 and 142, only two patients are alive, a case of rhabdomyosarcoma without disease evidence and another one of leiomyosarcoma with inguinal recurrence.
  
  
  CONCLUSIONS
  Paratesticular sarcoma is a rare malignant neoplasia of poor prognostic with variable history of disease in relation a histology subtype, but in general of bad evolution with fatal ending. The biological behavior of the tumor and history of the disease vary according to histological subtype, but in general the trend is poor with fatal outcome.
