title: [Epidermoid cyst of the testicle: presentation of a case].
abstract: OBJECTIVE
  To describe a case of epidermoid cyst of the testis, a rare lesion that warrants surgical exploration to confirm the diagnosis since its echo patterns are characteristic but not pathognomonic.
  
  
  RESULTS
  10 years earlier the patient had noticed an asymptomatic swelling of the right testis which did not cause infertility since he had two children over the last 6 years. Tumor markers AFP, BHCG and LDH fell within the normal ranges. Ultrasound evaluation with a high resolution 7.5 Mhz transducer revealed a 4 x 3.5 x 3.2 cm testicular mass surrounded by atrophic parenchyma. The patient underwent radical inguinal orchidectomy.
  
  
  CONCLUSIONS
  Epidermoid cyst is the benign variety of testicular teratoma. Two different forms exist: simple and mixed. Malignant components are present in the latter form. If the simple form is identified before substitution of the testicular parenchyma occurs, testis sparing surgery is justified; otherwise radical orchidectomy with inguinal exploration is indicated.
