title: [Spermatocytic seminoma with rhabdomyosarcomatous contingent].
abstract: BACKGROUND
  Spermatocytic seminoma is a relatively rare testicular tumour, not associated with another germ-cell tumour component and characterized by a favourable prognosis. However, discovery of a sarcomatous contingent modifies the prognosis.
  
  
  METHODS
  The authors report the case of a 50-year-old man with a history of right testicular swelling for 4 years, gradually increasing in size without vaginal effusion. Tumour markers were normal. Ultrasound demonstrated a very large semi-solid semi-cystic testicular mass with a long axis of 14 cm. Orchidectomy was performed.
  
  
  RESULTS
  Histological examination and immunohistochemistry of the orchidectomy specimen concluded on spermatocytic seminoma associated with a rhabdomyosarcomatous component.
  
  
  CONCLUSIONS
  Only 12 cases of spermatocytic seminoma with sarcomatous component have been reported in the literature The presence of a sarcomatous component confers a very poor prognosis to spermatocytic seminoma.
