One case of intraductal carcinoma of the parotid gland in a 67-year-old male patient is here introduced. The patient, who had a one-year history of a parotid mass, had undergone ultrasound and MRI examination that disclosed a 13x4x3 mm well delimited nodular mass of the accessory lobe of his left parotid gland. Ultrasound-guided Fine Needle Aspiration (FNA) had been performed by the clinician. The obtained smears showed widespread cellular necrosis in which cellular clusters with moderate and focally severe atypias displayed papillary and cribriform architecture and were admixed with sheets of epithelial cells with less striking nuclear atypias, squamous, or apocrine metaplasia...

BACKGROUND: Endoscopic ultrasound with fine-needle aspiration (EUS-FNA) is the most efficacious way to collect specimens from a solid lesion adjacent to the gastrointestinal tract and is performed with an internal stylet during puncture. However, its reinsertion into the needle is time-consuming. Controversy surrounds whether quality of cytology specimen improves with stylet use. We performed a meta-analysis comparing the use of stylet versus no stylet with EUS-FNA of gastrointestinal-related masses...

Early detection of neck lymph node (LN) recurrence is paramount in improving the prognosis of treated head and neck cancer patients. Ultrasound (US) with US-guided fine needle aspiration (FNA) and core needle biopsy (CNB) have been shown to have great accuracy for LN diagnoses in the untreated neck. However, in the treated neck with fibrosis, their roles are not clarified. Here, we retrospectively review 153 treated head and neck cancer patients who had received US and US-guided FNA/CNB. In multivariate logistic regression analyses, size (short-axis diameter >0...

In recurrent tonsillitis, the pathogenic bacteria are harbored in the tonsil core, and therefore cultures of superficial swab samples are not particularly accurate in identifying specific types of core bacteria. On the other hand, the results of fine-needle aspiration (FNA) cultures of core samples have been closely correlated with the findings of core cultures in excised tonsils, and both methods are far superior to surface swabbing. We conducted a prospective study to compare the accuracy of culture findings from tonsillar tissue obtained by surface swabbing, FNA sampling of the tonsil core in situ, and core sampling of the excised tonsil in children with recurrent tonsillitis...

Objectives: Fine-needle aspiration (FNA) of head and neck lymph nodes (LNs) is useful in diagnosing metastatic papillary thyroid carcinoma (PTC) and most commonly shows classic cytologic features of PTC. Metastatic PTC, however, may occasionally present with a pattern unfamiliar to most pathologists: atypical histiocytoid cells (AHCs). Methods: All PTC thyroidectomy specimens with associated FNA of LNs were retrieved from our files for 2007 to 2013. We aimed to assess cytologic features of metastatic PTC, as well as the presence of AHCs and their morphology...

BACKGROUND: Thyroid nodules are usually benign; however, 5 to 15% prove to be malignant. Fine-needle aspiration (FNA) has become the gold standard in the evaluation of thyroid nodules, especially in single nodule more than a centimeter and / or in smaller nodule with ultrasound characters of malignancy. METHODS: We evaluated retrospectively 179 patients with "undetermined" thyroid fine needle aspiration, undergoing surgery. We compared cytology and histology and we evaluated sex, age, the presence of thyroiditis and dimension of the indeterminate nodule as predictors of malignancy...

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA)...

INTRODUCTION: In patients with lung cancer, left adrenal glands (LAG) suspected for distant metastases (M1b) based on imaging require further evaluation for a definitive diagnosis. Tissue acquisition is regularly performed using conventional EUS-FNA. The aim of this study was to investigate the success rate of endoscopic ultrasound guided fine-needle aspiration using the EBUS scope (EUS-B-FNA) for LAG analysis. METHODS: This is a prospective multicenter study in consecutive patients with (suspected) lung cancer and suspected mediastinal and LAG metastases...

Most commonly used methods for sewer sulfide control involves dosing chemical agents to wastewater, which incurs high operational costs. Here, we propose and demonstrate a cost-effective and environmentally attractive approach to sewer sulfide control through urine separation and its subsequent conversion to nitrite prior to intermittent dosage to sewers. Urine collected from a male toilet urinal was fed to laboratory-scale sequencing batch reactors. The reactors stably converted roughly 50% of the nitrogen in urine to nitrite, with high abundance (at 17...

BACKGROUND & AIMS: Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the GI tract. Fine needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. METHODS: This is a multicenter, prospective randomized clinical trial from six large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion...

BACKGROUND AND OBJECTIVES: Subcentimetric (defined as <1 cm at short axis) lymph nodes are considered benign and there is limited literature on the results of fine needle aspiration (FNA) of these nodes. METHODS: Endoscopic ultrasound (EUS) guided FNA was done on 189 lymph nodes in 166 patients with pyrexia of unknown origin (n = 113) or malignancy (n = 53). Subcentimetric lymph nodes (Group A) were compared to nodes with short axis diameter ≥1 cm (Group B)...

BACKGROUND AND OBJECTIVES: Many cases of gastrointestinal (GI) tumors as lymphoma, adenocarcinoma, and most of submucosal tumors (SMT) such as gastrointestinal stromal tumor (GIST) and leiomyoma are difficult to diagnose as they frequently yield negative endoscopic biopsies. We evaluated the accuracy of endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) in the diagnosis of endoscopic biopsy negative GI tumors. PATIENTS AND METHODS: One hundred and nine patients with biopsy negative GI tumors were included in this prospective study...

BACKGROUND AND AIMS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is used for the diagnosis of pancreatic adenocarcinoma, but sometimes the method results in a false negative. Occasionally, an avascular area may be observed within the pancreatic adenocarcinoma tumor during contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS). The aim of this study was to evaluate whether the diagnostic sensitivity of EUS-FNA for pancreatic adenocarcinoma was affected by the presence of avascularity on CH-EUS...

Implications of assessing the proximal and far para-tracheal or sub-carinal nodes (para-tracheal [PTN] or sub-carinal [SCN]) associated with lower primary esophageal carcinomas (ECs) are unclear. To evaluate the value of endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) for PTN and SCN, we analyzed results by positron emission tomography (PET) avidity, 4 EUS node malignancy features, and EUS-FNA results in all patients with Siewert's I or II EC. Of 133 patients (PTN, n=102; SCN, n=31) with EUS-FNA, 47 (35%) patients had malignant node, leading to treatment modifications...

Pancreatic cysts are commonly found on cross-sectional imaging. The question arises in determining which lesions are premalignant or malignant and may require further testing, intervention, or follow-up. In pancreatic cysts without obvious malignancy on imaging, we approach them using the Four "S" Criteria. These are (1) symptoms that may be originating from the pancreatic cyst; (2) size of the cyst 2 cm or larger and/or main pancreatic duct greater than 5 mm; (3) survival of the patient, based on comorbidity index to determine surgical fitness; and then endoscopic ultrasound with fine needle aspiration (FNA) recommended to determine (4) solid component presence in the cyst, namely, nodule or thick walls, as well as to perform FNA to obtain cyst content...

Fine-needle aspiration (FNA) plays a key role in the early evaluation of patients with thyroid nodules; however, from 15% to 30% of FNA specimens are cytologically indeterminate. Molecular testing has proven useful when applied to indeterminate thyroid FNAs, and its use has been endorsed in the American Thyroid Association guidelines. In addition to the noncommercial ("in-house") application of v-Raf murine sarcoma viral oncogene homolog B1 (BRAF), rat sarcoma (RAS), rearranged in transformation/papillary thyroid carcinoma (RET/PTC), and peroxisome proliferator-activated receptor γ/paired box gene 8 (PPARγ/PAX8) testing, there are currently 3 commercially available molecular panels that vary in their relative reported performances, strengths, and limitations...
