title: [Prostatic granulomas revealing a peripheral T-cell lymphoma].
abstract: BACKGROUND
  The presence of granulomas on tissue biopsie has been reported in a wide range of disorders. The clinical presentation and the diagnostic work-up of granulomatosis can be difficult as it is illustrated in the following report.
  
  
  METHODS
  A 59-year-old patient was referred in 2002 for a granulomatous prostatitis. Physical examination was normal. Except for the increase of prostate-specific antigen (which motivated a biopsy), the laboratory results were normal. Thoracic CT-scan disclosed mediastinal lymph nodes. A minor salivary gland biopsy was consistent with the diagnosis of sarcoidosis. In 2004, the patient presented an epidermal necrolysis, and in 2005 the deterioration of general status raised suspicion of a lymphoproliferative disorder. Liver and bone marrow biopsies revealed a granulomatous process. Despite steroid therapy, the patient died. Autopsy discloses a anaplasic T cell lymphoma.
  
  
  CONCLUSIONS
  This report illustrates the relationship between sarcoidosis and lymphoma as a mode of presentation, a complication, or an accidental but misleading association? The association between anaplastic lymphoma and sarcoidosis is exceptional.
