... role of fine-needle aspiration (FNA) in the pancreatic lesions, different radiographic modalities and their evolution in the FNA of pancreatic lesions, and utility of rapid on-site evaluation of pancreatic cytology is also discussed. Guidelines on pancreatic pathology provided by the Papanicolaou...

... Abstract It is important to adequately process and triage the specimen obtained from fine-needle aspirations (FNAs) of pancreatic lesions. Many echo endoscopists rely on rapid on-site evaluation (ROSE) for adequacy of FNA from solid pancreatic lesions. The role of ROSE in FNA of pancreatic...

... Abstract Ultrasound-guided fine-needle aspiration (FNA) biopsy allows for accurate sampling of mass lesions. The diagnostic information from this procedure is maximized when the pathologist is intimately involved with specimen procurement, specimen triage, and interpretation. This chapter...

...Preliminary Aspects Despite the efforts towards automated diagnostic procedures, fine-needle cytology (FNC), with or without aspiration, smearing, rapid on-site evaluation (ROSE), and material management remain operator-dependent procedures that require manual and professional skills. Much...

...Introduction The major aim of this work was to thoroughly describe and illustrate the most common entities. Cytologic diagnostic criteria have not yet been established in some primary bone tumors/lesions that are not common targets for fine-needle aspiration (FNA) examination, or in some very...

... Abstract The optimum technique for biopsy assessment of the nature of a major salivary gland mass remains controversial. Fine needle aspiration cytology (FNAC) has been the traditional and popular choice, but sampling of cellular clusters is largely associated with high non-diagnostic and false...

... methodology for fine-mapping causal variants within these regions. We then consider progress in fine-mapping type 2 diabetes susceptibility loci, evaluating the evidence for allelic heterogeneity arising from multiple causal variants at the locus, interpretations of the underlying genetic architecture...

... specimen of the tumor. Fine-needle aspiration biopsy of uveal melanoma is being performed increasingly for prognostication purposes. Indications, instruments, surgical technique, complications, preparation and processing of the specimen, prognostic factors are described. Classically, the diagnosis...

... Although there is enough literature on fine needle aspiration biopsy (FNAB) of uveal tumors, the same is not true for retinal tumors, possibly because of the paucity of clear indications and guidelines. Certain general indications and contraindications for FNAB have been formulated based...

..., the globe blocks most of this entrance leaving only the space along the orbital rim accessible for fine needle aspiration (FNA). This makes FNA more challenging, and deep lesions will require precise positioning of the needle in terms of angle and depth. Furthermore, the orbit is traversed by numerous...

... innovations include refinement of fine needle aspiration biopsy (FNAB) technique, instrumentation and sample processing. This review includes appraisal of the imminent changes limited to the field of ophthalmic cytology. Technique and Instrumentations The techniques for intraocular biopsy vary...
