OBJECTIVE To assess the diagnostic value of aspiration cytology in individual cystic lesions of the ovary. STUDY DESIGN During a 42-month period, 235 cystic ovarian lesions were investigated by fine needle aspiration with cytologic examination (FNA). RESULTS Almost 56% (131/235) of the aspirates were devoid of diagnostic cells. The 104 diagnostic aspirates comprised 49 follicular cysts, 4 e...

AIMS To analyse the benefits and limitations of fine needle aspiration in the cytological differentiation of parenchymatous nodular goitres from follicular tumours in an endemic area. METHODS Cytological smears of fine needle aspirates from 31 parenchymatous nodular goitres were studied. A sample from the punctured nodules was fixed in formalin and stained with haematoxylin and eosin for hist...

BACKGROUND Atypia of undetermined significance (AUS) is a category that encompasses a heterogeneous group of thyroid aspiration cytology. It has been reclassified into two subgroups based on the cytomorphologic features: AUS with cytologic atypia and AUS with architectural atypia. The nuclear characteristics of AUS with cytologic atypia need to be clarified by comparing to those observed in Has...

Our aim was to assess malignancy risk in adenomatoid nodules and suspicious follicular lesions of the thyroid obtained by fine needle aspiration (FNA) cytology. Retrospective research was performed of 276 patients who underwent thyroid surgery after preoperative ultrasound-guided FNA diagnosis of either adenomatoid nodule, cellular follicular lesion, "suspicious for follicular neoplasm" or foll...

Tumors of parafollicular cells and nonepithelial tumors occur less frequently than tumors derived from follicular cells. This review summarizes the histologic and cytologic features of these neoplasms and the nonneoplastic diseases that often have to be included in the differential diagnosis of thyroid tumors. Also, the role of fine-needle aspiration biopsy and frozen section interpretation in ...

Introduction. Splenic tumor is usually found as an incidental finding on CT of abdomen. Traditionally, ultrasound (US) or computed tomography (CT) guided biopsies were employed for the purpose of sampling; however they have been reported to have a complication rate of 5.3%. Endoscopic ultrasound-fine needle aspiration (EUS-FNA) has been recently utilized for the purpose of sampling splenic tumo...

Zenker’s diverticulum is rarely seen in a clinical setting and may mimic a thyroid nodule. Fine needle aspiration cytology (FNAC) is effective in differentiating neck masses, and rarely has complications. FNAC of Zenker’s diverticulum presents with both squamous cells and bacteria while FNAC of thyroid nodular typically presents with follicular cells and colloid. (J Intern Med Taiwan 2016; 27: ...

Thyroid nodules are a very common clinical finding, and although the majority of them are benign, thyroid carcinoma accounts for about 5-15% of nodules. Fine-needle aspiration cytology (FNAC) is actually used for the differential diagnosis of these lesions. Although in most cases this examination clearly distinguishes benign from malignant lesions, some fine-needle aspiration (FNA) samples fall...

Background. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has attempted to standardize reporting and cytological criteria in aspiration smears. Aims. The objective of this study was to analyze the thyroid cytology smears by TBSRTC, to determine the distribution of diagnostic categories and subcategories, to analyze cytological features, and to correlate the cytopathology with...

AIMS To study the value of wide needle (19 gauge) aspiration cytology in the diagnosis of lymph node disease in Zambia in the absence of a trained cytologist. METHODS Patients (n = 304) referred for surgical biopsy of an enlarged peripheral lymph node were studied prospectively. Surgical biopsy was routinely preceded by 19 gauge needle aspiration of the same node; aspirates were stained by ha...
