Esquistossomose endocervical: relato de caso

Abstract

Schistosomiasis mansoni is found in different endemic areas of Brazil. It is a serious public health problem in Brazil and worldwide. Ectopic forms of the disease may affect the female reproductive system, representing a rare type of Schistosoma mansoni infection. A 26-year-old patient complained of vaginal discharge, dyspareunia and pain on palpation of the hypogastrium. Gynecological examination revealed an endocervical polyp. A biopsy was performed. Under microscopy, several granulomas surrounding degenerate and viable eggs of Schistosoma mansoni were seen. Treated with praziquantel, she was asymptomatic after four weeks of treatment. Vaginal discharge and dyspareunia may be secondary causes of cervicitis caused by Schistosoma mansoni. The search for eggs in routine vaginal smear or histological examination should be part of the gynecologic evaluation of patients from endemic areas, with the purpose of tracking ectopic schistosomiasis of the female genital tract.

Ovarian Manson's Schistosomiasis: Rare Diagnosis or Underestimated Prevalence?

“…3,4 Reports in the literature have drawn attention to the growing number of cases of ectopic forms of schistosomiasis. [5][6][7][8] Prominent among these is one of the severest presentations of this parasitosis: schistosomal myeloradiculopathy, caused by the formation of granulomas in the central nervous system that induce incapacitating lesions in the lower limbs of the individuals affected. 6,9,10 In cases of infection by Schistosoma haematobium, which affects the reproductive and urinary systems of both men and women, findings of granulomas in these tissues are common.…”

Ectopic forms of schistosomiasis mansoni in the second macroregion of Alagoas: case series report and review of the literature

“…However, it is believed that the anastomoses between the hemorrhoidal veins and vessels that drain the internal genitalia and vulva allow the migration of worms and egg embolization into the capillary bed, where they induce the formation of granulomas [14][15][16] .…”

“…Lesions may also represent a risk factor for infections due to sexually transmitted diseases, especially human immunodeficiency virus and human papilloma virus 13,15,17 . In the ectopic form of schistosomiasis involving the uterine cervix, postcoital, intermenstrual and post-menstrual bleeding, vaginal discharge and dysmenorrhea can occur -signs that are not direct consequences of schistosomiasis but result from its association with cervicitis (Figure 2A) 18 .…”

“…Considering that the prevalence of S. mansoni in municipalities of the northeastern states of Brazil is still high, it is believed that low notification rates and lack of protocols tailored to the investigation of ectopic forms are responsible for the absence of diagnoses of ectopic forms of this parasitic disease 15 . Also, it would be advisable to maintain a high degree of diagnostic suspicion to identify ectopic forms of the disease.…”

“…A esquistossomose mansônica é uma doença parasitária causada pelo helminto Schistosoma mansoni, que acomete pacientes do mundo inteiro (1) . No Brasil, estima-se que 25 milhões de pessoas vivam em áreas endêmicas, sendo o maior número de casos da enfermidade notificados nos estados do Nordeste, devido ao deficiente saneamento básico e má higienização sanitária da população (2,3) . É provável que esquistossomas parasitos de roedores (S. rodahini) associados à evolução dos primeiros hominídeos tenham dado origem ao S. mansoni (4,5) .…”
