Salivary gland tumor aspiration cytology is a useful preoperative test to guide the most appropriate clinical and surgical management for these patients. Although salivary gland cytology is often useful to distinguish between non-neoplastic lesions, benign neoplasms and malignant neoplasms, there remain many challenges in this area. Specifically, t...

Ancillary molecular testing has emerged as a promising way to refine the preoperative risk stratification of thyroid nodules with indeterminate fine needle aspiration (FNA) biopsy results. Commercially available molecular tests for thyroid FNAs include those that analyze samples for mutations and gene fusions, gene expression alterations, microRNA ...

Biliary brushing cytology has become the standard of practice for the investigation of strictures of the biliary and pancreatic duct systems. The methodology however has a limitation in that it has low diagnostic sensitivity when only cytologic evaluation is used. A number of testing methodologies have been applied to brushing specimens in an attem...

The cytologic evaluation of serous effusions may be challenging for a number of reasons. Distinction of benign, reactive conditions from malignancy represents the main focus when examining these specimens. The morphologic diagnosis of malignancy may be difficult due to the relative paucity of abnormal cells. In other situations, cellularity is not ...

Ancillary techniques play an essential role in pulmonary cytopathology. Immunoperoxidase and special stains are by far the most common ancillary techniques used in cytopathology; however, the role of molecular diagnosis is growing, especially in the fields of pulmonary oncology and infectious disease. In this article, we review the uses of ancillar...

Pulmonary cytology is a challenging diagnostic tool, and it is usually evaluated considering medical history and radiological findings in order to reach an accurate diagnosis. Since the majority of lung cancer patients have an advanced stage at diagnosis, a cytological specimen is frequently the only material available for diagnosis and further pro...

The association between high-risk genotypes of human papillomavirus (hr-HPV) and cervical cancer is well established. As hr-HPV testing is rapidly becoming a part of routine cervical cancer screening, either in conjunction with cytology or as primary testing, the management of hr-HPV-positive women has to be tailored in a way that increases the det...

Aside from its diagnostic importance, urinary tract endoscopy is an uncomfortable, expensive, and time-consuming procedure. Patients with a history of urothelial carcinoma remain at an increased risk for recurrence and the development of de novo disease; most have had exposure to carcinogenic risk factors for decades prior to their first diagnosis ...

Objective: Utilizing cytology specimens for molecular testing has attracted increasing attention in the era of personalized medicine. Cytology specimens are clinically easier to access. The samples can be quickly and completely fixed in a very short time of fixation before tissue degradation occurs, compared to hours or days of fixation in surgical...

The Papanicolaou (PAP) test is widely used to screen for cervical cancer. All high-grade lesions such as atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H), and high-grade squamous intraepithelial lesion, identified on a PAP test should be followed-up by a confirmatory cervical biopsy. In this review, we disc...
