Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

The Role of Bone Marrow Aspiration and Bone Marrow Biopsy in Diagnosis of Bone Marrow Metastases

Background: Bone marrow is the site of many malignant disorders and it is one of the common places for solid tumors to metastasize. Examination of the bone marrow aspirate and biopsy is a routine procedure performed for assessment of various conditions such as cytopenias, hematologic neoplasms, nonmalignant disorders and metastatic neoplasms. Methods: The patients were referred to the Hema...

Feasibility and Diagnostic Yield of Endoscopic Ultrasonography-Guided Fine Needle Biopsy With a New Core Biopsy Needle Device in Patients With Gastric Subepithelial Tumors

As treatment decisions for patients with gastric subepithelial tumors (SETs) largely depend on the histopathologic diagnosis, noninvasive and effective tissue acquisition methods are definitely required for proper management of gastric SETs. Recently, a new endoscopic ultrasonography-guided fine needle biopsy (EUS-FNB) device with ProCore reverse bevel technology was developed. We aimed to eluc...

Core needle biopsy in the diagnosis of bone lesions

Clear cell chondrosarcoma may be difficult to distinguish from metastatic clear cell renal carcinoma. Clear cell chondrosarcoma is strongly positive for 5100 and negative for epithelial markers. Clear cell carcinoma is cytokeratin positive and may also be positive with SiQO. S100 may also be useful in confirming grade 3 chondrosarcoma and mesenchymal chondrosarcoma. SiQO may assist in distingui...
