Abstract:The term schistosomiasis encompasses a group of infectious disorders caused by five species of the genus Schistosoma, a blood trematode of outstanding importance in tropical areas. Some of these disorders have long been associated with malignant neoplasia, the most striking association being between disease caused by Schistosoma haematobium, the predominant etiological agent of urinary schistosomiasis, and squamous cell carcinoma of the bladder, a relatively uncommon vesical cancer in non-endemic areas.

“…Schistosomiasis has long been associated with malignant neoplasia. 4 Some authors have hypothesized a causal relationship between schistosomiasis and carcinoma of the bladder, bowel, kidney and prostate. 5 To data only 17 cases of prostatic adenocarcinoma and concomitant gland schistosomiasis have been described (S. haematobium identified in 11 cases, S. mansoni in five cases and not specified in one case).…”
ResumoA shistossomíase humana, a segunda doença parasitária mais devastadora, é comum nos países em desenvolvimento, mas é rara na Europa. O envolvimento do aparelho urogenital deve-se sobretudo a infecção por Schistosoma haematobium. A schistossomíase tem sido associada com neoplasias malignas, desde há algum tempo. Alguns autores têm colocado a hipótese de existir uma relação causal entre schistossomíase e cancro do intestino, rim, bexiga e próstata. Até à data, estão descritos apenas 17 casos de adenocarcinoma e schistossomíase da próstata concomitantes. Como um exemplo raro de uma potencial complicação de schistossomíase não tratada, relatamos um caso de schistossomíase urinária incidentalmente diagnosticada após prostatectomia radical por adenocarcinoma da próstata, num homem Africano de 62 anos, a residir numa área não endémica.

“…The most striking association occurs in areas with a high prevalence of urinary schistosomiasis due to S. haematobium, such as Africa and the Middle East. In these regions there is a predominance of squamous cell carcinoma of the bladder, a relatively rare form of cancer in non-endemic regions 29,30 . In China, where colorectal cancer reaches relatively high incidence rates in endemic areas, the association between this type of neoplasia and diffuse colitis due to S. japonicum infection has also been suggested 30,31 .…”

Introduction: Ectopic forms of schistosomiasis are those in which the parasitic element is localized outside the portal system, the natural habitat of the helminth. Although the prevalence rates of schistosomiasis are high in Brazil, clinical and epidemiological data on ectopic forms of the disease are still scarce. Methods: Cross-sectional, retrospective and descriptive epidemiological study in which cases with a confirmed histopathological diagnosis of an ectopic form of schistosomiasis were analyzed. The cases were selected from a database of the anatomic pathology files of a referral center. Results: Of the 21 cases identified, seven affected the female genital tract and five the male genital tract; four cases were identified in the peritoneum; two cases involved lymph nodes and two involved adipose tissue; and renal involvement was detected in one case. Conclusions: The lack of knowledge of the clinical presentation of ectopic forms of schistosomiasis makes the early identification and treatment of this form difficult, with direct implications in the reduction of morbidity and mortality in endemic areas.
“…Following high infestation rates, major lung involvement with respiratory symptoms is usually reported 17 . The urogenital presentation is not uncommon in endemic areas, and may be associated with local cancers 4 . The skin may be involved, but is not associated with malignant tumors 10 .…”
Seven cases of patients with ectopic schistosomiasis from the State of Sergipe, Brazil, are presented (five involving skin, one ovarian and one adrenal). Data were collected from surveying the clinical records and anatomopathological reports in the files of the dermatology and pathology clinics of the University Hospital of the Federal University of Sergipe, from 1995 to 2005. The patients' mean age at diagnosis was 21.1 years. In the dermatological cases, full cures were achieved after treatment with oxamniquine. In the ovarian case, there was an association with embryonic carcinoma: this patient underwent surgery with adjuvant chemotherapy and praziquantel treatment, with satisfactory evolution. The adrenal case was associated with adenoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
