“…In spite of well-known etiological relationships between S. haematobium and bladder cancer, there is very limited number of cases of bladder carcinoma secondary to S. mansoni infestation in the literature [13,14] . All of the 5 cases reported in the literature were from the rural regions of Brazil.…”

“…The case reported here shows a rare form of ectopic schistosomiasis. Only four other cases of bladder involvement were reported around the world, all of them in Brazil [14]. In 1944, a study by necropsy performed by Meira [15] showed the first case in Brazil.…”

“…Mitre et al [17] in 1980 described another case of a 23-year-old man with dysuria and terminal hematuria who was treated with oxamniquine in association with transurethral resection of the lesions. Lopes and colleagues [14] in 2006 reported the case of a 36-year-old man whose treatment was also transurethral resection in association with oxamniquine. In our case, transurethral resection biopsy was of great importance in diagnosis, due to a suspected bladder cancer.…”

Bladder cancer is the most common malignancy of the urinary tract and it affects four times more men than women. The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. Schistosoma mansoni infection causes an endemic disease in Brazil (schistosomiasis) and gastrointestinal disorders are very common, but disease of the urinary tract is atypical. The aim of this study was to describe a case of a patient presenting schistosomiasis (S. mansoni) and urothelial bladder carcinoma. In this case, a 37-year-old man with intermittent painless gross hematuria was investigated. Cystoscopy revealed a small pedunculated lesion in the bladder dome. Transurethral resection revealed urothelial carcinoma of the bladder, low degree, unrepresentative of the muscular layer of the bladder. After 30 days, a new transurethral resection was performed to sample acquisition of the muscular layer on the basis of the scar. Histopathology was negative for malignancy (Tumor Node Metastasis: TNM-T1). During this procedure, there was evidence of dark rounded lesion in the bladder dome. It was excised and the histopathology showed viable eggs of Schistosoma mansoni. The patient was treated orally with oxamniquine and remained in oncological monitoring with cystoscopy quarterly and serial clinical evaluation. This case reveals a rare finding of Schistosoma mansoni in the bladder and urothelial bladder carcinoma coexisting in the same patient.

The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. In this case, a 48-year-old woman with macroscopic hematuria, dysuria and a palpable abdominal mass was investigated. Ultrasound showed a large exophytic mass in the bladder. Transurethral resection of the bladder revealed viable eggs of Schistosoma mansoni. The patient was treated clinically with oxamniquine and surgery was performed to resect the large mass. This case shows that schistosomiasis Mansoni in the bladder can simulate bladder cancer.Key-words: Schistosoma mansoni. Bladder cancer. Leiomyoma. Schistosomiasis. Oxamniquine. RESUMOÉ bem conhecida a relação entre tumor vesical e Schistosoma haematobium, porém somente casos esporádicos de infecção vesical por Schistosoma mansoni foram relatados. Neste caso, uma mulher de 48 anos com hematúria macroscópica, disúria e massa abdominal palpável foi investigada, ultra-sonografia mostrou uma grande massa exofítica na bexiga. A ressecção transuretral de bexiga evidenciou ovos viáveis de Schistosoma mansoni. A paciente foi tratada clinicamente com oxaminiquine e uma cirurgia foi realizada para ressecar a grande massa. Este caso mostra que a esquistossomose mansônica vesical pode simular um câncer vesical.Palavras-chaves: Schistosoma mansoni. Câncer de bexiga. Leiomioma. Esquistossomose. Oxaminiquine. Schistosoma mansoni infection is an endemic disease inBrazil and gastrointestinal affection is very common. However, there have only been anecdotal reports of bladder infection due to Schistosoma mansoni, in contrast with the known risk of developing bladder cancer in patients affected by Schistosoma haematobium. CASE REPORTA 48-year-old female patient originating from an endemic area for schistosomiasis in Brazil (Bahia) was seen at our hospital because of abnormal menstrual bleeding, gross hematuria, urinary frequency and dysuria. Physical evaluation showed a palpable painful mass in the pelvic region. Ultrasound showed a large exophytic lesion filling almost the entire bladder (Figure 1).Cystoscopy revealed a large regular rounded mass of diameter 8 cm without any visible stalk. Transurethral biopsy showed chronic cystitis and viable eggs of Schistosoma mansoni. Colonoscopy showed ulcers in the rectum-sigmoid.The patient was treated clinically with oxamniquine. Her renal function deteriorated and ultrasound showed bilateral dilatation of the ureter. A double-J catheter was then placed in both ureters. The patient continued to present impaired renal function and FigURE 1Ultrasound on the bladder showing a bladder mass.
