BACKGROUND Cervical smears exhibiting unequivocal features of 'low grade squamous intraepithelial lesion' (LSIL) are occasionally also admixed with some cells suspicious for, but not diagnostic of, 'high grade squamous intraepithelial lesion' (HSIL). Only a few studies, mostly reported as abstracts, have evaluated this concurrence. In this study, we evaluate the current evidence that favors a d...
BACKGROUND The standard for reading cervical cytology is for a cytoscreener to manually search across an entire slide for abnormal cells using a conventional microscope. Automated technology can select fields of view to assess abnormal cells, which allows targeted reading by cytoscreeners. In the Manual Assessment Versus Automated Reading In Cytology (MAVARIC) trial, we compared the accuracy of...
OBJECTIVES This is a European Commission (EC)-funded ongoing study known as the LAMS (Latin American Screening) study, where PAP smear/liquid-based cytology and screening colposcopy were compared with i) three optional screening tools [visual inspection with acetic acid (VIA), or Lugol's iodine (VILI), cervicography] and with ii) Hybrid Capture II from a) conventional samples and from b) self-s...
OBJECTIVE Hyperchromatic crowded groups (HCG), a term first introduced into the cytology literature by DeMay in 1995, are commonly observed in Pap tests and may rarely be associated with serious but difficult to interpret lesions. In this study, we specifically defined HCG as dark crowded cell groups with more than 15 cells which can be identified at 10x screening magnification. METHODS We ev...
OBJECTIVE Continuous expression of E6- and E7-oncogenes of high-risk human papillomavirus (HPV) types is necessary for the development and maintenance of the dysplastic phenotype. The aim of the study was to determine the sensitivity and specificity of the APTIMA HPV mRNA assay (Hologic) in predicting future development of high-grade cervical intraepithelial neoplasia (CIN) among high-risk HPV-...
The Warthin-like variant of papillary thyroid carcinoma (WL-PTC) was first introduced by Apel et al. 1 in 1995 as an extremely rare subtype of papillary thyroid carcinoma (PTC) that is characterized by papillary architecture, lined by Hürthle cells, with classical cytologic features of PTC cells, and a heavy lymphocytic stroma of the papillary core. WL-PTC is now classified in the World Health ...
BACKGROUND Liquid-based cytology (LBC) for cervical screening would benefit from laboratory practice guidelines that define specimen adequacy for reporting of slides. The evidence base required to define cell adequacy should incorporate both ThinPrep™ (TP; Hologic, Inc., Bedford, MA, USA) and SurePath™ (SP; BD Diagnostics, Burlington, NC, USA), the two LBC systems used in the UK cervical screen...
Urinary cytology has a well-established role in the detection and monitoring of urothelial carcinoma. The main strength of cytology is the high specificity for high-grade urothelial carcinoma and carcinoma in situ, but it has a low sensitivity for low-grade, non-invasive tumors. There are several other limitations of cytology. Cytology of the upper urinary tract and after intravesical therapy w...
