RESUMO
Extra-enteric infections by Blastocystis spp. have rarely been documented. Here, we report a case of extra-enteric blastocystosis in a patient with minimal cervicitis symptoms. A 47-year-old Hispanic female patient was attended in a primary health centre in Michoacan state, Mexico, for her routine gynaecological medical examination. As only symptom, she referred to a slight vaginal itching. The presence of several vacuolar-stages of Blastocystis spp. were identified by Papanicolaou staining; molecular identification was attempted by culture-PCR sequencing of a region of 18S gene from cervical and faecal samples obtained 2 months after cytological examination, even when patient declared that she tried self-medicating with vaginal ovules. Blastocystis ST1 was identified only in the faecal sample. The presence of Blastocystis spp. in the cervix of a patient with scarce symptomatology, demonstrates the extraordinary flexibility of this microorganism to adapt to new environments and niches.

Eight hundred samples of vaginal swabs were taken from women with active sexual life attending the Cervicouterine Cancer Opportune Detection Service at the Familial Medicine Unit No. 18 of the National Institute of Social Security, to study the incidence and prevalence of vaginal trichomoniasis, the presence of yeasts of the genus Candida and their relationships with clinical features of vulvovaginitis. Identification of parasites was made by means of direct examination with light microscope; 14.39 per cent of candida vulvovaginitis against 3.13 per cent of trichomoniasis was found; in only five cases the two parasites were associated. Leukorrhea and vaginal pruritus were the major symptoms found and the most affected anatomical regions were vaginal walls in trichomoniasis and cervix in candidiasis. Although vaginal trichomoniasis is a worldwide distributed parasitosis, its frequency is very variable, not so vaginal candidiasis, which is more frequent.

A case of squamous cell carcinoma associated with amebiasis is presented. Protozoa identified as Entamoeba histolytica were found in a routine Papanicolaou smear and in the cervical biopsy of a young woman following the initial diagnosis of cervical cancer and the institution of a radiation therapy regimen. No amoebae were found in repeated stool specimens. The late detection and diagnosis of amebiasis precluded any possible changes in the management of the case. Initial follow-up for the carcinoma demonstrated that the patient was not responding well to therapy; her failure to return to the clinic precluded long-term follow-up and treatment for the amebiasis.
