Fine needle aspiration biopsy (FNAB) of the kidneys is a safe procedure with an excellent diagnostic yield based on established criteria for primary lesions with a sensitivity of 80% to 92% and specificity of 83% to 100% in diagnosing malignancy.…
Currently, fine needle aspiration biopsy (FNAB) is the first diagnostic procedure used in patients presenting with a mass in the lung, mediastinum, or chest wall on chest x-ray (CXR) or computed tomography (CT) or CT positron emission tomography (PET) scan,…
The number of pancreatic fine needle aspiration biopsies (FNAB) has increased substantially over the past decade due to (1) the development of new imaging and guidance mechanisms, specifically endoscopic ultrasound scopes with the ability to perform an ultrasound directed FNAB;…

The technique of fine needle aspiration biopsy (FNAB) of breast has developed over the past 60 years to be an extremely useful and accurate method of diagnosing palpable and impalpable lesions. Breast FNAB can attain sensitivity in the range of…
Fine needle aspiration biopsy (FNAB) of the thyroid is currently the most accurate and cost-effective way of examining thyroid nodules (2009 American Thyroid Association guidelines). The number of thyroid FNAB has increased recently due to the number of thyroid nodules…

Fine needle aspiration biopsies (FNAB) of salivary gland and head and neck lesions can represent a major component of the total volume of FNAB in a pathologist’s practice. These specimens can also be the most challenging due to the number…
FNAB Pattern Recognition Numerous texts over the past 50 years have described the attributes of fine needle aspiration biopsy (FNAB). The purpose of this text is not an attempt to replace these salient works in diagnostic cytopathology of FNAB lesions.…
Once a diagnosis of primary cutaneous melanoma has been established by a pathologist, the treatment of choice is usually complete removal by surgical excision. Surgery is to accomplish two goals: (a) to permit complete assessment of the entire tumor for…
