“…The reported lower number of passes with EUS-FNB was in concordance with a meta-analysis comparing standard FNA and ProCore FNB 12 . However, the diagnostic yield was identical between the standard FNA needle and the FNB needle, and a subset analysis of pancreatic biopsies from a recent randomized study were unable to detect any differences in the cellularity yield, mean number of passes and reported adverse events 26 .…”

Background and study aim Due to the scarcity of specific data on endoscopic ultrasound (EUS)-guided fine-needle biopsies (SharkCore) FNB in the evaluation of pancreatic lesions, we performed a prospective study of the diagnostic performance of EUS SharkCore FNB in patients with pancreatic lesions. The aim of this study was to evaluate the diagnostic accuracy. Patients and methods Single-center prospective study of 41 consecutive patients referred for EUS-FNB from October 2015 to April 2016 at our center. EUS-FNB was obtained in a predefined setting regarding the procedure and pathological evaluation. Data regarding demographics, lesion, technical parameters, and diagnostic accuracy were obtained. Results The study included 41 consecutive patients (22 males (54 %); median age 68 years). The average size of the lesions was 28 mm (median: 30 mm). A diagnostic specimen was identified in 40 (98 %) cases during microscopy with an average of 2.4 passes. The route was trans-duodenal in 20 cases (49 %). The histological diagnosis of the specimens was malignant in 29 cases (71 %), benign in 8 (20 %), suspicious in 2 (5 %), atypical in 1 (2 %) and in 1 (2 %) no material for microscopic evaluation was obtained. This led to a diagnostic accuracy of 93 %, sensitivity of 91 % and a specificity of 100 %. 2 cases (5 %) of self-limiting bleeding were observed. The diagnosis at follow up was malignant in 32 (78 %) of the patients. Conclusions EUS-FNB of pancreatic mass lesions with the SharkCore needle produced specimens with a diagnostic accuracy of 93 %. The procedure was safe and easy to perform, and these data support the use of EUS-FNB in a routine setting.

“…The pathologic diagnoses, cytomorphologic characteristics, immunocytochemical stains, and ISH studies were reviewed and recorded for all available cases. The overall specimen cellularity was assessed with a 4‐point scale like the one reported by Othman et al and used previously by Allison et al as follows: 1 = scant, 2 = hypocellular, 3 = moderately cellular, and 4 = hypercellular.…”

Background Human papillomavirus (HPV)–related squamous cell carcinoma (SqCC) of the oropharynx is an epidemiologically and clinically distinct form of SqCC that is associated with an improved prognosis. However, HPV‐related small cell carcinoma of the oropharynx is a rare and newly described variant that is associated with aggressive clinical behavior and poor outcomes. To date, fewer than 2 dozen reports of this entity exist in the literature, and there is no discussion of cytopathologic features. This article reports 6 cases and discusses the salient cytomorphologic findings, ancillary studies, and challenges when this entity is encountered. Methods Anatomic pathology archives were searched to identify patients with a diagnosis of HPV‐related small cell carcinoma of the oropharynx. Medical records were reviewed to document the following: age, sex, smoking status, other relevant clinical history, primary location, treatment, and clinical outcome. Both p16 and high‐risk HPV in situ hybridization (ISH) studies were positive in at least 1 specimen from each patient. The pathologic diagnoses, cytomorphologic characteristics, immunocytochemical stains, and HPV ISH studies were reviewed and recorded for all available cases. Results Six patients with 11 cytopathology specimens of HPV‐related small cell carcinoma of the oropharynx were identified. The mean age was 61.3 years, and all patients died with widely metastatic disease (mean, 23 months; range, 12‐48 months). Mixed small cell carcinoma and SqCC components were present in half of the cases. Conclusions The identification of a small cell component can be reliably performed with cytology preparations and is crucial because this (and not the HPV status) determines the prognosis.
