Abstract
Bilateral testicular germ cell tumors (BTGCT) occur in 1 to 4% of patients with testicular cancer and of these, 10-15% are synchronous. Overall, BTGCT represents less than 0.5% of all new cases of testicular cancer. There are few reports in the literature of synchronous BTGCT with different histology. We present the case of a 30-year-old man who presented to our genitourinary tumor unit with a bilateral increase of testicular volume. After initial assessment, a testicular ultrasound showed the presence of solid tumors in both testes. Staging studies were negative for metastatic disease. The patient was referred to the fertility clinic for sperm banking and later underwent a bilateral radical orchiectomy. The histopathology evaluation revealed a 5.5 cm right-sided mixed germ cell tumor and a 1.5 cm left-sided testicular seminoma. Because patient's poor compliance for surveillance was identified as a risk factor for relapse and poor outcome, adjuvant chemotherapy was favored. The patient underwent one cycle of bleomycin, etoposide and cisplatin (BEP). After four years of follow up, the patient shows no evidence of relapse, either clinically or radiologically. In men unlikely to carry out successful surveillance; active treatment is the preferred option for preventing disease recurrence, even in patients with no risk factors. The physician must consider all available therapeutic measures in this scenario to achieve the best possible therapeutic result.
