Testicular schistosomiasis caused by schistosoma mansoni: A case report from Brazil

Abstract

Testicular schistesomiasis by Schistosoma mansoni is exceedingly rare, with only 11 cases reported In PubMed. We report a new case from Brazil. A 31-year-old man from the northeast region of the country presented with a 2 cm nodule in the right testis. Ultrasonography showed a well-delimited hypoechoic tumor, suggestive of a granulomatons lesion. Magnetic resonance imaging revealed an irregular tunica albuginea signal. A biopsy showed interstitial tissue with schistosome ova and granuloma formation. The nodule was excised, and the patient was treated with oxamniquine. He has remained symptom free for 10 years. A testicular nodule should raise suspicion of numerous pathologies, including schistosomiasis. Treatment should include therapy with oxamniquine or prazlquantel, and, nodule excision should be done whenever possible.
