title: [Solitary fibrous tumour of the testes (SFT)].
abstract: BACKGROUND
  Testicular masses in adults are most likely seminomatous or non-seminomatous germ cell tumours. Paratesticular tumours are far less frequent. Most lesions within this category are variants of fibrous pseudotumours. Solitary fibrous tumours (SFT) with characteristic (hemangiopericytoma-like) vascular structures are rare neoplasms that in the vast majority arise in the pleura, although extrapleural localisations in virtually every organ have been reported.
  
  
  METHODS
  A 64-year-old male nursing case was presented with a testicular swelling on the left side and recurrent testicular pain. Physical examination revealed a distinct mass at the left spermatic cord. The tumour marker levels were normal. The patient's history included an HIV infection as well as neurosyphilis. The sonographic examination showed a heterogeneous and hyperperfused tumour, MRI examination a 3.2 x 4.3 cm measuring heterogeneous tumour above the left epididymis. An inguinal orchiectomy was performed due to the unclear dignity. The histological examination revealed a solitary fibrous tumour.
  
  
  CONCLUSIONS
  In cases of paratesticular tumours, rare tumours like solitary fibrous tumours have to be considered. Certainty regarding the dignity of the tumour can only be achieved by surgical exposure and excision.
