OBJECTIVE: Basal cell adenoma (BCA) is an uncommon benign epithelial neoplasm of salivary glands, which was first described by Kleinsasser and Klein in 1967 and which derives its name from the monomorphic basaloid appearance of tumor cells. This tumor represents 1-2% of all salivary gland epithelial tumors; the most common site of occurrence is the parotid gland. It usually arises in adults over 50 years of age with slight female prevalence. STUDY DESIGN: We analyzed 5 cases of parotid lesions investigated by fine needle aspiration cytology at a single institution between 2002 and 2018...

BACKGROUND: The most frequent metastases to the thyroid originate in the kidney, lung or breast. Colorectal adenocarcinoma represents less than 4% of metastases to the thyroid gland. Solitary metastases of colorectal cancer with no other manifestation of disseminated cancer disease are exceedingly rare. Within the Bethesda Classification for Reporting -Thyroid Cytopathology, metastases are included in Diagnostic Categories "Suspicious for Malignancy" and "Malignant." CASES: We present 2 cases of colorectal adenocarcinoma metastatic to the thyroid gland, diagnosed by fine-needle aspiration (FNA)...

OBJECTIVE: Although cytology testing is considered a valuable method to diagnose tumors that are difficult to access such as hepato-biliary-pancreatic (HBP) malignancies, its diagnostic accuracy remains unclear. We therefore aimed to investigate the diagnostic accuracy of cytology testing for HBP tumors. STUDY DESIGN: We performed a retrospective study of all cytology samples that were used to confirm radiologically detected HBP tumors between 2002 and 2016. The cytology techniques used in our center included fine needle aspiration (FNA), brush cytology, and aspiration of bile...

OBJECTIVE: Rapid on-site evaluation (ROSE) has been shown to improve adequacy rates and reduce needle passes. ROSE is often performed by cytopathologists who have limited availability and may be costlier than alternatives. Several recent studies examined the use of alternative evaluators (AEs) for ROSE. A summary of this information could help inform guidelines regarding the use of AEs. The objective was to assess the accuracy of AEs compared to cytopathologists in assessing the adequacy of specimens during ROSE...
