title: Testis T-cell lymphoma. Presentation of 2 cases and review.
abstract: OBJECTIVE
  To present two clinical cases of testicular T cell lymphomas and perform a review of this condition.
  
  
  RESULTS
  Case 1. Forty-two year old male presenting with painful mass in the right testicle which appeared 2 months earlier. Testicular ultrasound showed diffuse increase in size of the testicle, with alteration in its echogenicity. The patient underwent orchidectomy, and based on histopathological and immunohistochemical tests, a peripheral nonspecific T cell lymphoma was diagnosed. Case 2. Forty-four year old male who presents with a 3 month history of left testicular enlargement without pain associated with reddish-brown macular lesions in the thigh and back and subsequent involvement of the right side of the scrotum. The ultrasonography showed testicles with increased size, with echogenicity altered diffusely. Left orchidectomy was performed and sent for histopathological and Immunophenotypic study which revealed a non-Hodgkin peripheral T cell lymphoma.
  
  
  CONCLUSIONS
  T cell lymphomas involve the testis infrequently, which deserve special attention because of the poor prognosis and the need to make an appropriate diagnosis which could lead to a better therapeutic strategy.
