PURPOSE To compare the effectiveness of fine needle aspiration cytology (FNAC) with core biopsy (CB) in the pre-operative diagnosis of radial scar (RS) of the breast. PATIENTS AND METHODS A retrospective analysis was made of all radial scars diagnosed on surgical histology over an 8-year period. Comparison was made between the results of different preoperative needle biopsy techniques and sur...
Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is routinely performed for establishing tissue diagnosis in patients with gastrointestinal tumors. The concept of delivering chemotherapy based on molecular markers and the ability to establish a reliable diagnosis in lieu of an onsite cytopathologist has fuelled the recent trend in procuring core tissue by means of EUS-guided fine n...
The optimum technique for histological confirmation of the nature of a parotid mass remains controversial. Fine needle aspiration cytology (FNAC), which has traditionally been used, is associated with high non-diagnostic and false negative rates, and ultrasound (US)-guided core biopsy and frozen section have been explored as alternatives. US-guided core biopsy is more invasive than FNAC, but is...
Thyroid scintigraphy is now rarely used in the work-up of a thyroid nodule except in the presence of a low TSH value. Therefore, autonomously functioning thyroid nodules (AFTNs) with a normal TSH value are diagnosed only in the rare medical centers that continue to use thyroid scan systematically in the presence of a thyroid nodule. In this review, we discuss the prevalence of AFTN with a norma...
Primary thyroid lymphomas (PTL) are extremely uncommon neoplasms accounting for 5% of all thyroid malignancies. There are very few small series and occasional case reports of fine needle aspiration cytology (FNAC) of PTL in literature. We present an interesting and rare case of PTL diagnosed on FNAC. FNAC is an important tool in the diagnosis of thyroid lymphoma. Journal of Cytology 2007; 24 (3...
BACKGROUND Some studies have shown that a preoperative high concentration of thyroglobulin (Tg) in wash out of fine-needle aspiration cytology of cervical lymph nodes mandate therapeutic lymph node dissection. However, there is disagreement about the minimum concentration of Tg which could have diagnostic value. Hence, according to our literature review, this study is the first one which design...
The role of fine needle biopsy and cytological diagnosis in the preoperative evaluation of thyroid nodules is reviewed on the basis of the current literature as well as the authors' personal experience. Technical aspects and guidelines for reporting thyroid samples are discussed in some detail. The main emphasis is on diagnostic pitfalls, those which may lead to a false-negative diagnosis, to a...
Cancer spread along the needle track following fine needle aspiration biopsy is said to be a rare complication. The authors report a case of subcutaneous implantation of hepatocellular carcinoma following ultrasono-guided fine needle aspiration biopsy. The patient, a 67-year-old Korean male was found to have a large hepatocellular carcinoma diagnosed by fine needle aspiration biopsy. Four month...
