“…We have previously reported that women with schistosomiasis did not have menstrual irregularities; therefore a direct effect on hormones or ovarian function is not likely (30)(31)(32). The study was conducted in a remote area and patients were poor.…”

“…In our settings, such lesions have been described in appendix causing perforation with peritonitis [4], and schistosomal eggs was also seen within the prostate cancers [5]. Ovarian schistosomiasis has been described causing chronic granulomatous inflammation producing ovarian pseudotumor, and it was also seen in fallopian tube in association with carcinoma [6, 7]. Schistosomiasis of the cervix presents like other cervical condition such as cervicitis or cancer, and cervical cancer with schistosoma eggs had been described in Tanzania [8].…”

Schistosomiasis is a communicable disease which commonly involves urinary bladder causing hematuria, or large bowel causing bloody stool. The common species encountered in this lake region surrounding Lake Victoria in Tanzania are Schistosoma haematobium and Schistosoma mansoni. Complications can lead to portal hypertension due portal fibrosis in liver, and fibrosis in lung can lead to pulmonary hypertension; this commonly seen with S. mansoni. Major complications of S. maeametobium are chronic cystitis with squamous metaplasia with subsequent development of squamous cell carcinoma. Involvement of spinal cord causing paraplegia has been observed in S. haematobium. Other unusual pathology of schistosomiasis has been described, such as involvement of the appendix, ovary, prostate, and cervix. Here, we present a case of schistosomiasis in a 9-year-old boy who presented with left scrotal pain for one year which was accompanied by scrotal swelling; surgical exploration was done, and the finding was hydrocele and atrophic testes with nodules on the surface. Histological examination reveals atrophic testis and heavy active granulomatous inflammation with schistosoma eggs consistent with Schistosoma haematobium in the tunica vaginalis.

“…S. mansoni infestations are referred to as ectopic when the eggs or the adult form of the parasite is found outside the portal system, for example, in the skin, central nervous system, thyroid, myocardium, esophagus, stomach, gall bladder, pancreas, suprarenal, or urogenital tract [15]. These presentations may affect individuals with any parasite load, even years after the initial exposure [16].…”

Schistosomiasis is a parasitic infection that is highly prevalent worldwide, with a variety of species being responsible for causing the disease. In Brazil, however, the only identified species is Schistosoma mansoni. The adult parasites inhabit the blood vessels of the hepatic portal system of the main host. The disease may range from being asymptomatic to provoking liver damage or portal hypertension. Furthermore, ectopic schistosomiasis may develop, and several hypotheses have been raised to explain the occurrence of the disease. This paper describes two cases, one in a 39-year-old woman and the other in a 47-year-old woman. Both had similar symptoms of pain and abdominal distension caused by a large abdominal/pelvic mass. Histopathology of the ovary showed a mucinous cystadenocarcinoma of the intestinal type in the first patient and a papillary serous carcinoma in the second, with both tumors containing viable eggs of Schistosoma mansoni. The neoplasms probably serve as a migratory route for the adult parasites and the embolization of eggs. Nevertheless, there is insufficient evidence to confirm the malignization of a benign lesion due to the presence of Schistosoma mansoni. Few cases have been reported in the international literature on the association between ovarian schistosomiasis and neoplasms.

Schistosoma mansoni: an unusual cause of ovarian pseudotumor

Abstract: Ovarian ectopic S. mansoni is rarely reported in the most current literature; however, this actual proportion of ovarian Manson's schistosomiasis may not represent the real female genital involvement rates and reflect an underestimation of internal genital disease.
