BACKGROUND: In situ hybridization for human papillomavirus (HPV) messenger RNA (HPV RNA ISH) recently was introduced as an ancillary tool in the diagnosis of cervical squamous intraepithelial lesions, and can aid in the distinction between low-grade squamous intraepithelial lesions (LSILs) versus reactive/negative biopsies. Prior work has shown that up to one-half of cases originally diagnosed as LSIL are reclassified as negative/reactive by expert consensus review of morphology, and negative HPV RNA ISH results most often correlate with an expert diagnosis of negative/reactive...

BACKGROUND: Urine cytology specimens are essential for screening and monitoring high-grade urothelial carcinomas. However, inconsistent reporting and equivocal diagnostic categories have remained a challenge. The Paris System for Reporting Urinary Cytology (TPS) was developed to provide clear cytomorphologic criteria for urine cytology specimens. Significant correlation between the surgical biopsy diagnosis (SD) and TPS diagnosis (PD) has been established in lower urothelial tract carcinomas, but to the authors' knowledge limited information is available regarding upper urinary tract carcinomas...

Anal cancer incidence and mortality have been increasing over the past decade. Although the incidence in the general population remains low, it is much higher in certain subgroups, including those living with human immunodeficiency virus and men who have sex with men. Approximately 90% of anal squamous cell cancers are caused by infection with carcinogenic human papillomavirus (HPV). Given the common etiology between anal and cervical carcinogenesis, screening for anal cancer has been proposed in certain high-risk populations using strategies adapted from cervical cancer prevention...

BACKGROUND: Fine-needle aspiration (FNA) is widely accepted in the preoperative management of salivary gland lesions. The proposed Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) aims to standardize reporting terminology. Studies regarding the risk of malignancy (ROM) for the proposed categories continue to evolve. The current retrospective study applied the MSRSGC to assess ROM for salivary gland lesions and focused on the "indeterminate" categories. METHODS: A total of 627 salivary gland FNA specimens obtained from 2011 through 2016 were retrieved, with follow-up available for 373 cases...

BACKGROUND: SMARCB1 (INI-1)-deficient sinonasal carcinoma (IDSNC) is a newly described, poorly differentiated carcinoma. Herein, the authors describe the cytopathologic features of IDSNC in fine-needle aspiration (FNA) samples. METHODS: The pathology archives of 2 academic institutions were searched for cases of IDSNC with available cytologic materials. All available slides were reviewed and a detailed morphological analysis was performed. RESULTS: Six cases were identified from 6 patients...

BACKGROUND: Recent guidelines recommended the optional deferral of colposcopy for postmenopausal women with low-grade squamous intraepithelial lesion (LSIL) Papanicolaou (Pap) test results and negative human papillomavirus (HPV) testing. The objective of the current study was to assess the histopathologic follow-up of Cervista and Aptima high-risk HPV (hrHPV) testing in patients with LSIL cytology. METHODS: Women with LSIL Pap test results and Cervista or Aptima hrHPV testing results were retrospectively identified from June 2013 through July 2017...

BACKGROUND: Diagnosing giant cell-rich bone tumors can be challenging on limited biopsies. H3 histone family member 3A (H3F3A) (G34W/V/R/L) mutations are present in the majority of giant cell tumors (GCTs) of bone and H3 histone family member 3B (H3F3B) (K36M) mutations are present in nearly all chondroblastomas, but are absent in histologic mimics. Mutation-specific immunohistochemistry (IHC) is highly specific for GCT and chondroblastoma in surgical excisions. The objective of the current study was to validate H3G34W and H3K36M IHC in the diagnosis of giant cell-rich bone tumors on fine-needle aspiration and core needle biopsy specimens...

BACKGROUND: The American Thyroid Association (ATA) recommends fine-needle aspiration (FNA) biopsy of nodules measuring >1.5 cm with low-suspicion sonographic patterns or >1.0 cm with high/intermediate-suspicion features. Routine biopsy of nodules <1 cm is not recommended. However, despite these recommendations, subcentimeter nodules are often referred for FNA biopsy. METHODS: This was a retrospective chart review of consecutive thyroid FNAs during an 18-month period (1157 patients, 1491 nodules, 2016-2017) to evaluate age, sex, medical history, diagnoses, and follow-up...

BACKGROUND: After increased requests for biopsies for clinical trials and biomarker research, the University of Pittsburgh Medical Center created a clinical trial research service that partnered pathology, radiology, and medicine to facilitate rapid on-site evaluation (ROSE) of fine-needle aspiration (FNA) and/or core needle biopsy (CNB) samples to confirm the presence of tumor in these studies. METHODS: Clinical trial coordinators organized biopsies for patients needing tumor samples for trials, and informed the cytopathology and radiology team...

BACKGROUND: Anal cytology may be useful for evaluating lesions associated with human papillomavirus (HPV) in individuals at increased risk for anal cancer. METHODS: Liquid-based cytology was used to assess anal cytological lesions among human immunodeficiency virus (HIV)-infected and HIV-uninfected men who have sex with men (MSM). The Linear Array HPV genotyping test was used for HPV detection. RESULTS: This cross-sectional study included 1021 MSM, of whom 388 were HIV-infected (38...

BACKGROUND: An important goal of The Paris System for Reporting Urinary Cytology (TPS) is to reduce unnecessary atypical diagnoses given to urinary tract cytology (UTC) specimens. Since implementation of TPS at the study institution in 2016, the institutional atypical rate has declined only slightly. The authors speculated that TPS might not have had an immediate impact because several faculty members were involved in TPS committees and because TPS contains elements that already had been integrated into institutional practice...

BACKGROUND: The Paris System for Reporting Urinary Cytology (TPS) was published in November 2015. It focuses on the diagnosis of high-grade urothelial carcinoma (HGUC) and provides criteria with which to define the category of atypical urothelial cells (AUC). The objective of the current study was to compare two 1-year consecutive periods before and after use of TPS. METHODS: A total of 1634 and 1814 urine cytology cases, respectively, were analyzed before and after use of TPS...

BACKGROUND: Making a specific diagnosis of pancreatic cysts preoperatively is difficult. The new disposable Moray micro forceps biopsy (MFB) device allows tissue sampling from the pancreatic cyst wall/septum and aims to improve diagnosis. This study compares the diagnostic performance of the MFB with the current conventional analysis of pancreatic cyst fluid (PCF). METHODS: A total of 48 patients sampled with MFB were identified. Cysts were classified as mucinous on PCF based on extracellular mucin/mucinous epithelium, carcinoembryonic antigen (CEA) levels ≥192 ng/mL, or KRAS/GNAS mutation...

BACKGROUND: The 2016 American Thyroid Association guidelines recommend multiple endocrine neoplasia testing and evaluation for pheochromocytoma before thyroidectomy after a thyroid fine-needle aspiration biopsy (FNA) is positive for medullary thyroid carcinoma (MTC). In the current study, the authors examined the reasons why FNA was unable to definitively diagnose MTC preoperatively, with attention to morphologic patterns that can be misleading. METHODS: Cases of MTC diagnosed on thyroid surgical resection for which there was a prior FNA and slides available for review were included (28 cases)...

BACKGROUND: The identification of BRAF mutations in thyroid cancer has prognostic and therapeutic implications. Although the gold standard for identifying BRAF mutations is molecular testing, the ability to perform BRAF p.V600E immunostaining on fine-needle aspiration (FNA) samples can facilitate the rapid triaging of patients to treatment options. METHODS: A total of 50 thyroid carcinoma FNA samples, including papillary (29 samples), poorly differentiated (10 samples), anaplastic (9 samples), and Hurthle cell (2 samples) carcinomas, with a known BRAF p...

BACKGROUND: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) has been proposed to standardize salivary gland fine-needle aspiration (FNA) diagnoses. This study assessed salivary gland FNA results and risk of malignancy (ROM) rates at the University of North Carolina as well as the interobserver reliability (IOR) of the atypia of undetermined significance (AUS) and salivary gland neoplasm of uncertain malignant potential (SUMP) categories. METHODS: The electronic medical record was searched for FNA cases from 2010 to 2017 with subsequent surgical resections...
