... 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...

... (FNAB) samples. Clinical Features Breast and lung carcinoma dominate the primary malignancies that metastasize to the uvea. The breast is the most common primary site in women and the lung is the most common primary site in men [ 3 - 6 ]. In a large series of uveal metastases, the distribution...

... with a thickness of less than 3 mm and a largest basal diameter under 10 mm [ 4 ]. Considering the latter, there is no evidence of an increased risk of uveal melanoma local diffusion following a correctly performed fine needle aspiration biopsy (FNAB) [ 5 , 6 ]. Moreover, uveal melanoma shows some...

... Fine needle aspiration biopsy (FNAB) has widespread acceptance as an effective diagnostic test for uveal melanoma, albeit indicated in only a small minority of cases [ 1 - 3 ]. Clinical examination, including ophthalmoscopic evaluation, almost always establishes the diagnosis ( fig. 1...

... 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...

.... On the other hand, case B represents benign tumours: painless, without diplopia and even asymptomatic. The behaviour of the ophthalmologist must be different in these 2 cases. In case A, a quick diagnosis is needed, as was done with FNAB the same day of the appointment, and chemotherapy was applied rapidly...

.... a The tumor is hypoechoic and homogenous with a hyperechoic (slightly white periphery) attesting to its vascular nature. b The tumor is abutting the main pancreatic duct resulting in proximal dilatation of the duct (arrow), making it unresectable via enucleation. c EUS-FNAB with the needle (25 G) well...

The scope of practice for clinical cytologists is markedly expanded when USFNA is added to their repertoire. In addition to palpable masses...

... and Aspirational Tumour Biopsies In the case of intraocular fluid biopsies and tumour fine needle aspiration biopsies (FNAB), it is preferable that these are delivered to the investigating laboratory without fixative, if possible within 1 hour of the procedure. However, if longer delays are anticipated...

.... Fine-needle aspiration biopsy (FNAB) is a technique that was described and used to obtain cytological specimen from neoplasias more than 100 years ago. Although it was applied to different tumors, the first report on an aspirative puncture in a solid intraocular tumor was done by Jakobiec et al...
