LOPES, Roberto Iglesias; LEITE, Kátia Ramos; PRANDO, Décio and LOPES, Roberto Nicomedes. Testicular schistosomiasis caused by Schistosoma mansoni: a case report from Brazil. Braz J Infect Dis [online]. 2007, vol.11, n.5, pp. 523-524. ISSN 1678-4391. http://dx.doi.org/10.1590/S1413-86702007000500015.
Testicular schistosomiasis 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 granulomatous 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 praziquantel, and nodule excision should be done whenever possible.
