Endoscopic ultrasound guided fine needle aspiration (EUS-FNA) has become an essential tool in the management of multiple diseases. Its accuracy is related to different aspects of the technique, one of the most important being the experience and interaction of the endosonographer and pathologist. Certain studies over the past years have highlighted the importance of having rapid on-site evaluati...

We report a case of large iris melanocytoma in a child diagnosed by fine needle aspiration biopsy. In this interventional case report, cytologic features typical of melanocytoma were obtained by fine needle aspiration biopsy (FNAB). FNAB can be used in difficult diagnostic cases if a good sample is obtained, this technique has an accuracy of more than 99% in tumors larger than 3 mm; however, fa...

CASE REPORT. A 78-year-old woman presented with a five week history of a lump in her left breast and a four week history of a blocked right nostril. On examination, she had a hard, immobile mass in the breast and there was also obvious enlargement of her right nasal area, extending towards the eye and maxillary sinus. It was assumed that she had a carcinoma of her breast with a secondary metast...

UNLABELLED Thyroid nodules are a common pathology of the thyroid gland. Thyroid fine-needle biopsy (FNB) is a technique used as the first step in the assessment of thyroid nodules. Some au- thors have demonstrated the superiority of nonaspiration compared with aspiration biopsy. AIM The objective was to assess whether there are significant differences between the two thyroid biopsy techniques...

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...

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...

Thyroid nodules Thyroid nodules are common, occurring in almost two-thirds of some populations; among these only about 7% are malignant (1). The most important question with any new discovered thyroid nodule is, “is this malignant?” The main arbiter of malignancy or benignity remains fine needle aspiration. Given the resources involved, doing a fine needle aspiration cytology (FNAC) in every di...
