BACKGROUND AND STUDY AIMS Two 22G needles with similar designs, apart from the absence (A) or presence of a side port (B), are available for endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA). The side port was designed to increase diagnostic yield but this advantage was unproven. This study evaluated the difference in diagnostic yield between both needles in pancreatic masses. P...

Objective. To determine the role of imaging-cytology correlation in reducing false negative results of fine-needle aspiration (FNA) at thyroid nodules. Methods. This retrospective study included 667 nodules 1 cm or larger in 649 patients diagnosed as benign at initial cytologic evaluation and that underwent follow-up ultrasound (US) or FNA following a radiologist's opinion on concordance betwee...

We describe a case of an 82-yr-old woman presenting with a thyroid nodule and axillary mass thought to be a metastasis. Fine-needle aspiration (FNA) revealed the axillary nodule to be a chondroid syringoma. We report here the cytologic features of chondroid syringoma and recommend the use of FNA in the evaluation of cutaneous and subcutaneous lesions in general.

hashimoto’s thyroiditis is associated with an increased risk of developing papillary carcinoma of thyroid. we hereby report a case of hashimoto’s thyroiditis with papillary carcinoma in a 45-year-old ear old female diagnosed on fine needle aspiration cytology (fnac) which was later confirmed on histopathological examination .such an occurrence, when both lesions are picked up on fnac in a patie...

Primary extradural meningiomas presenting as scalp swelling is uncommon. Their diagnosis by fine needle aspiration is rare as majority of the lesions are hyperostotic. Primary intraosseus meningiomas involving the skull constitute only about 2% of meningiomas and are often mistaken for other primary or secondary bone tumors. The authors report a case of primary calvarial meningioma involving th...

The aim of the study was to determine the incidence of coexistence of papillary carcinoma and Hashimoto's thyroiditis in cytologic material. Cytologic findings were collected from 10508 patients that underwent ultrasound-guided fine needle aspiration cytology (FNAC) of the thyroid. Hashimoto's thyroiditis was found in 2156 (20.5%) and papillary carcinoma in 269 (2.6%) of 10508 patients with FNA...

background: clinically frank thyroid nodules are common and believed to be present in 4% to 10% of the adult population in the united states. in the current literature, fine needle aspiration biopsies are considered to be the milestone of a model which helps the physician decide whether a certain thyroid nodule needs a surgical approach or not. a considerable fact is that sensitivity and specif...
