Concomitant testicular infection by Zika virus and Schistosoma mansoni in a Brazilian young boy / Infecção testicular associada com Zika vírus e Schistosoma mansoni em jovem brasileiro

Sumary The identification of a escrotal mass without pain or report of trauma should be investigated to rule out scrotal cancer. We report the case of a young Brazilian boy who underwent orchiectomy after magnetic resonance imaging (MRI) and duplex scan (DS) indicating a high possibility of cancer. Blood exams ruled out the possibility of cancer. Testicular biopsy was not indicated. After surgery the diagnostic was extensive orchiepididymitis by Schistosoma. In endemic areas orchiepididymis by Schistosoma should be investigate to avoid unnecessary surgeries. This patient was also infected with Zika virus.

Resumo A identificação de massa escrotal sem relato de dor ou trauma deve ser investigada a fim de afastar a possibilidade de câncer escrotal. O artigo reporta o caso de um jovem brasileiro que apresentou massa escrotal com essas características. Ressonância nuclear magnética (RNM) e ultrassonografia (US) indicaram grande possibilidade de câncer. Os marcadores tumorais sanguíneos estavam normais, e a biópsia não poderia ser realizada. O resultado anatomopatológico diagnosticou extensa fibrose esquistossomótica, associada a quadro clínico e sorológico de Zika vírus concomitantemente. Em regiões endêmicas, pacientes com alterações escrotais devem ser pesquisados a fim de evitar cirurgias desnecessárias.

Testicular schistosomiasis as differential diagnosis for testicular nodules: a case report

Despite its infrequent occurrence, testicular schistosomiasis forming pseudo-tumors can be considered in the differential diagnosis of testicular tumors, especially in areas where the parasitic disease is endemic. In this report, we present a case of testicular schistosomiasis caused by Schistosoma mansoni and mimicking a testicular neoplasm. We describe the patterns of a testicular nodule on ultrasonography and magnetic resonance images in a 46-year-old man. The nodule was removed after a pre-operative diagnosis of a non-malignant lesion. Histology demonstrated granulomas with epithelioid macrophages and eosinophils around S. mansoni eggs within a fibrous tissue that formed a nodular structure.

Testicular schistosomiasis caused by Schistosoma mansoni: a case report from Brazil

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.

Testicular schistosomiasis mimicking tumour

Schistosomiasis or bilharziasis is a disease caused by Schistosoma. When infecting men the most common parasites are Schistosoma mansoni, Schistosoma japonicum and Schistosoma haematobium. The Schistosoma mansoni is the only endemic parasite in Brazil. We present a case of testicular schistosomiasis simulating malignancy. The case was treated successfully by excisional biopsy and praziquantel therapy. A review of the literature is discussed.

Bilharziosis testicular / Testicular biharziosis

Se aportó un nuevo caso de schistosomiasis testicular a la literatura, se hizo especial énfasis en la forma tumoral de su presentación y la ausencia de otras manifestaciones urinarias
