BACKGROUND Thyroid cancer (TC) comprises 1% of all carcinomas and is the most common malignancy of the endocrine system. The disease is more common in women, with its peak morbidity observed in 40-50-year-old patients. The main risk factors include radiation, iodine deficiency, hereditary background, and genetic mutations. Among all diagnosed thyroid nodules, 5%-30% will evolve into cancer. The...

Specimens obtained with endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) are often tiny and fragmented leading to an inconclusive and doubtful diagnosis. To overcome the limitations of EUS-FNA in the cytological diagnosis of pancreatic adenocarcinoma (PCA), we evaluated whether quantification of the S100P protein combined with EUS-FNA reliably discriminated between PCA and benign p...

Teratomas are tumours which derived from all the 3 germ cell layers: endoderm, mesoderm and ectoderm with varying proportions. Cervical teratomas in children almost always benign but locally aggressive. They can present respiratory distress immediate excision is required. The cervical teratoma an uncommon entity rarely reported Indian medical literature particularly on FNA. We a case of anterio...

OBJECTIVE To form and assess a set of diagnostic ultrasound criteria to select malignant nodules for fine-needle aspiration (FNA) cytology and reduce number of FNA biopsies. METHODS In this prospective observational service evaluation study, 171 thyroid nodules that underwent FNA cytology were independently scored by two observers for established nodular sonographic characteristics for malign...

BACKGROUND/AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and Trucut biopsy (TCB) are sensitive techniques for diagnosing mediastinal lesions, but it is unclear how either one or both should be used to obtain a pathologic diagnosis. The objective of our study was to evaluate whether EUS-TCB impacts the diagnosis of mediastinal lesions after the initial on-site review of EUS-...

BACKGROUND/AIMS Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose gastrointestinal submucosal tumors (SMTs). Although rapid on-site evaluation (ROSE) has been reported to improve the diagnostic accuracy of EUS-FNA for pancreatic lesions, on-site cytopathologists are not routinely available. Given this background, the usefulness of ROSE by endosonograph...

Evaluation of deep-seated lymphomas by fine-needle aspiration (FNA) can be challenging due to their reduced accessibility. Controversy remains as to whether FNA and ancillary techniques can be used to diagnose deep-seated lymphomas reliably and sufficiently for clinical management. Most published studies are favorable that endobronchial ultrasound (EBUS)/endoscopic ultrasound (EUS)-FNA plays an...

The main purpose of thyroid FNA (fine needle aspiration) is to separate malignant and possibly malignant nodules from benign thyroid lesions. Every patient with thyroid nodule is a candidate for FNA. Before a decision to perform an FNA, a complete history, a physical examination directed to the thyroid and cervical lymph nodes, a serum thyrotropin level, and thyroid ultrasound should be obtaine...

BACKGROUND The axillary nodal status is essential to determine the stage of disease at diagnosis. Our aim was to prospectively assess the diagnostic accuracy of ultrasonography-guided fine-needle aspiration (US-FNA) for the detection of metastasis in axillary lymph nodes in patients with breast cancer (BC) and its impact on the therapeutic decision. MATERIALS AND METHODS Ultrasonography (US) ...

CONTEXT In patients with suspected lung cancer, the presence of mediastinal lymph node metastasis is a critical determinant of therapy and prognosis. Invasive staging with pathologic confirmation is recommended. Many methods for staging exist; mediastinoscopy, an invasive procedure requiring general anesthesia, is currently regarded as the diagnostic standard. OBJECTIVE To compare the diagnos...
