RESUMO
OBJECTIVES: To report a rare case of left renal cell carcinoma causing simultaneous acute left varicocele. We also performed a bibliographic review. METHODS: We present the case of a male adult who was diagnosed as having a left varicocele during a medical exam at his work center and referred to the urology clinic. On physical examination a left flank and hypochondrium mass was found. We analyze the diagnostic tests performed and possible therapies. RESULTS: With the diagnosis of left hypernephroma the patient underwent surgery. A big lower pole and medial portion kidney tumor displacing neighbor structures was found, and left radical nephrectomy was performed. CONCLUSIONS: Although it was easy to diagnose a hypernephroma with the diagnostic tests performed, the clinical presentation is not frequent, neither is the sudden onset of left varicocele. Currently, after 8 years of follow-up, the patient has normal blood-ultrasound tests.
