“…They should not be confused with other parasitic ova, pollen grains or with contaminated vegetable cells. [28] Pollen grains are microscopic structures enclosed in two layers. The outer layer may be smooth or rough with warts, grains or troughs.…”

Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination. We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis.

“…15 Damp areas of room, in cellars and basement, drain pipes, food stores and kitchen are all sources of Aspergillus contamination. 29,30 The cervicovaginal smear collection and its processing till it is interpreted involve various steps which may potentially produce a contamination in ill controlled environment. 31 While visualizing the cervix, the speculum and water used to facilitate its insertion may be contaminated.…”

Background: Aspergillus is a ubiquitous fungus known to cause aspergillosis in immunocompromised patients. The involvement of female genital tract by this fungus is rarely described. Reports of finding Aspergillus in cervicovaginal smears have appeared.Method: A comprehensive literature search was conducted from the websites of Pubmed Central, the US National Library of Medicine's digital archive of life sciences literature (http://www.pubmedcentral.nih.gov), and Google Scholar. And All articles displayed using the search words "Aspergillus and cervicovaginal smear" were included in this review. Books that published relevant articles in this field were also considered. Result:The Aspergillus is identified in smears by conidiophores and characteristic hyphae against a background of squamous cells and inflammatory cells. It should be confirmed and characterized by culture. Conclusion:Contamination should be ruled out in all the cases of Aspergillus in cervicovaginal Papanicolaou smear. Treatment should be done to prevent serious consequences in the patients if pelvic surgery is done and in a potential situation when patient develops an immunocompromised state in future.

“…While a variety of intrinsic and extrinsic contaminants, including spores, pollen and plant cells, can be found in cytology smears [5,6,7,8,9,10,11,12,13], to the best of our knowledge, we are not aware of such structures being reported in urinary diversion urine specimens. However, very similarly appearing vegetable cells have previously been reported in Papanicolaou (PAP) tests, which were attributed to be due to contamination from vaginal pessaries and creams [14].…”

Objective: We identified unique vegetable cell-like structures in urinary diversion specimens. This study aimed to describe their cytomorphology and prevalence and to investigate the possible origin of these contaminants. Study Design: A 10-year retrospective review of urinary diversion urine specimens with reported vegetable cell-like structures was performed. Data regarding patient demographics, previous history and specimen cytomorphology were recorded. To determine their prevalence, 100 urinary diversion cases were screened. Stoma materials were evaluated as possible contaminant sources. Results: A total of 11 urine cases from 7 patients (mean age 64 years; male/female ratio 2.5:1; all with ileal conduits) were identified with contaminating vegetable cell-like structures. These thick-walled cells contained dense, smudged cores and pericentral clearing. In 27% of cases, the specimens were less than optimal or unsatisfactory for evaluation due to low cellularity and associated lubricant material. No contaminating vegetable cell-like structures were found in the 100 screened cases. Stoma care products tested did not yield any morphologically similar structures. Conclusion: Vegetable cell-like structures may rarely be identified as a contaminant in urinary diversion specimens, possibly from stoma care material. Associated lubricant may affect specimen adequacy. These vegetable cell-like structures must be distinguished from true pathologic structures such as koilocytes or parasitic ova.
