Objectives: Primary pancreatic lymphoma (PPL) is rare, mimicking pancreatic ductal adenocarcinoma (PDAC) clinically and radiologically. The aim of this study is to evaluate the clinical, radiologic, and pathological characteristics of PPL diagnosed by fine-needle aspiration (FNA) in our institution.
Methods: Patient clinical, radiologic, and pathological information was collected from the electronic health record system.
Background: The evaluation of lymph nodes (LN) by fine-needle aspiration cytology (FNAC) is routinely used in many institutions but it is not uniformly accepted mainly because of the lack of guidelines and a cytopathological diagnostic classification. A committee of cytopathologists has developed a system of performance, classification, and reporting for LN-FNAC.
Methods: The committee members prepared a document that has circulated among them five times; the final text has been approved by all the participants.
Context.—: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is routinely used to evaluate mediastinal lymph nodes (LNs), especially for cancer staging. There are limited large studies evaluating the cytologic, radiologic, and clinical features of F-fluorodeoxy glucose positron emission tomography-computed tomography-positive (PET-CT+) LNs.

In addition, patients with classic morphology and a high proliferation index (HPI), also have reduced survival. Although variants have been defined, to the authors' knowledge the ability to detect these subtypes by fine-needle aspiration biopsy (FNAB) has not been described.

Methods: Specimens of cytological diagnosed with EHE in effusion fluids between 2002 and 2009 were retrieved from the pathology files at MD Anderson Cancer Center.
Introduction: The need for real time anatomic pathology services has grown as healthcare systems, traditionally found at large medical centers, expand into smaller communities. The placement of a pathologist is not cost-, time-, or resource-efficient. Telecytopathology can provide rapid offsite evaluation of cytology tissues.

We used RNA interference to examine the effects of AURKA overexpression in human bladder cancer cells. Knockdown had minimal effects on cell proliferation but blocked tumor cell invasion.

We evaluated the sensitivity of FNAB in diagnosing and grading FLs using a multiparameter approach in a large cancer center.
Methods: We retrospectively identified CNBs of lymph nodes diagnosed as FL that also had a concurrently acquired FNAB on the same site.
Background: Excisional biopsies are typically used to diagnose lymphoma, but data suggest that endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is equally effective. In this study, we determined whether EBUS-TBNA could accurately diagnose and subtype lymphoma.
Methods: The cases of patients who had undergone EBUS-TBNA for suspected lymphoma were retrospectively reviewed.
Pancreatic metastases are rare, ranging from 2% to 5% of pancreatic malignancies. Differentiating a primary pancreatic malignancy from a metastasis can be difficult due to similarities on imaging findings, but is crucial to ensure proper treatment. Although transabdominal ultrasound, computed tomography, and magnetic resonance imaging provide useful images, endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is often needed to provide a cytologic diagnosis.

We describe a case of pulmonary artery intimal sarcoma diagnosed on cytologic material obtained by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) biopsy with rapid on-site evaluation (ROSE). The aspirate showed loosely cohesive clusters of pleomorphic malignant spindled and epithelioid cells.

We reviewed our experience using endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for diagnosis of pancreatic tumors to identify clinical and cytopathologic characteristics of metastatic disease. We reviewed all cases of tumors metastatic to the pancreas evaluated at The University of Texas MD Anderson Cancer Center and The Methodist Hospital in Houston, Texas during the period from 2002 to 2012.

Methods: Data were reviewed on 220 FNA biopsies taken from thyroid bed lesions in 195 patients who had undergone thyroidectomy for thyroid carcinoma. Thyroid bed FNA results were compared with clinical follow-up, including neck dissection results.
Granular cell tumor rarely occurs in the thyroid. This case report describes the cytologic features of a granular cell tumor seen in a fine needle aspirate obtained from a 27-year-old woman with a gradually enlarging thyroid nodule. The aspirate showed single as well as syncytial clusters of cells with abundant granular cytoplasm.

In this retrospective study, the authors determined the utility of EBUS-TBNA biopsy in the evaluation of mediastinal lymphadenopathy at a high-volume cancer center.
Materials And Methods: The pathology database was searched for all patients who had undergone EBUS-TBNA biopsy of mediastinal lymph nodes over a one-year period.
Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) biopsy is routinely used to stage lung cancer; however, its usefulness in diagnosing lymphoproliferative disorders has not been well established. In this retrospective study, we determined the utility of EBUS-TBNA in evaluating mediastinal lymphadenopathy in patients with suspected lymphoproliferative disorders.
Methods: The authors searched the pathology database at their institution to identify all patients who had undergone EBUS-TBNA biopsy for possible lymphoproliferative disorders.
Here, we have prospectively isolated and characterized, for the first time, clonogenic cells with self-renewal capacities from mantle cell lymphoma (MCL), a particularly deadly form of non-Hodgkin's lymphoma (NHL). Self-renewal and tumorigenic activities were enriched in MCL cell fractions that lacked expression of the prototypic B-cell surface marker, CD19. CD45+CD19- cells represented a relatively small fraction of the total MCL tumor cells; however, they recapitulated the heterogeneity of original patient tumors on transplantation into immunodeficient mice.

Examination of the urine is a comprehensive screen of both the upper and lower urinary tract and is ideal for detecting both primary bladder UC and synchronous or metachronous, multifocal UCs that commonly occur because of a "field effect." This field effect is the result of both clonal and random genetic abnormalities that have resulted from exposure to carcinogens (most frequently in tobacco smoke) in conjunction with the individual's ability to repair DNA damage.

Fluorescence in situ hybridization (FISH) has been shown to be more sensitive than cytology in the detection of UC. The current study evaluated the use of FISH for detecting UC.

Experimental Design: We evaluated 59 NSCLC cases with stage I through IV disease and 24 controls. PBMCs and matched tumors were hybridized with 2 two-color [3p22.
Background: Fine-needle aspiration (FNA) of lymph nodes is commonly used to assess disease progression in patients with small lymphocytic lymphoma (SLL). Although cytologic features are helpful for diagnosing typical SLL and transformed large-cell lymphoma (tLCL), SLL in accelerated phase (SLLacc) is more difficult to diagnose. Additional tests are needed to identify those patients who are transforming to a higher-grade lymphoma.

The human telomerase RNA gene (hTERC) is located in the chromosome 3q26 region, and its product, telomerase, is involved in the maintenance of chromosome length and stability. Upregulation of telomerase is in general associated with tumorigenesis.
