مقدمه: پیدایش گره های تیروئید مشکل بالینی شایعی است که به دلیل احتمال بدخیمی دارای اهمیت است. بررسی سیتولوژی آسپیراسیون سوزنی ظریف (fnac) به عنوان یک روش ساده، ایمن و دقیق در ارزیابی گره های تیروئید، پذیرش گسترده ای یافته است. مطالعات متعدد در زمینه ارزش تشخیصی fnac تیروئید، با به کار بردن روش های متفاوت، میزان حساسیت، ویژگی، ارزش اخباری مثبت ومنفی و دقت تشخیصی متفاوتی را گزارش کرده اند. مواد و...
Albeit being rare, the testicular lymphoma is most common malignancy in elders. In early stages, its symptoms are non-specific and can mimic other underlying diseases. The available knowledge of cytology on this entity not adequate. case when a clinician comes across enlargement case, decision has to be made send patient for FNAC. Similarly, pathologist who assessing should also make whether pe...
Background & Objective: Abdominal cutaneous and subcutaneous nodules are uncommon lesions which may be benign or malignant. Majority of the malignant nodules are metastatic in origin and may be the initial presentation of primary malignancy, hence an early diagnosis is important. Our aim was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous and s...
BACKGROUND Immunocytochemistry (ICC) on formalin-fixed paraffin embedded cell blocks is an ancillary tool commonly recruited for differential diagnoses of fine needle aspiration cytology (FNAC) samples. However, the quality of conventional cell blocks in terms of adequate cellularity and evenness of distribution of cytologic material is not always satisfactory for ICC. We introduce a modified a...
The results of a consecutive series of 1,349 fine needle aspiration (FNA) biopsies from the head and neck region of 1,193 patients has been reviewed in order to evaluate the efficacy of this method in the diagnosis of tuberculous lymphadenopathy (TBLN). Of the 108 patients whose fine needle aspiration cytology (FNAC) showed granulomatous changes, 68 had subsequent surgery and histological confi...
Three hundred twenty patients were subjected to ultrasound guided fine needle aspiration cytology (FNAC) over a 3 year period (April 2006 - March 2009). These included liver (125 cases), lung (81 cases), abdominal and mediastinal lymph nodes (29 cases), ovary (14 cases), omentum (12 cases), pancreas (10 cases), kidney (10 cases), mediastinum (8 cases), gall bladder (8 cases) etc. The aim of thi...
BACKGROUND/AIM Fine needle aspiration cytology (FNAC) of the thyroid gland has been used as an initial investigative procedure of thyroid nodule(s) in the Department of Pathology at the Institute of Oncology of Vojvodina for more than 20 years. This procedure is rapid, inexpensive and technologically simple, yet it has found only limited, albeit increasing acceptance in medical practice in Serb...
PURPOSE To evaluate the role of fine needle aspiration (FNAC) as a diagnostic tool in cases of orbital and ocular adnexal masses. Cytological findings were correlated with histopathological diagnosis wherever possible. METHODS FNAC was performed in 29 patients of different age groups presenting with orbital and ocular adnexal masses. Patients were evaluated clinically and investigated by non-...
There is some “grey zone” in thyroid cytology where the diagnostic efficacy declines sharply rendering it difficult to categorize the lesions resulting in discrepancy. So, a cross-sectional study was conducted to determine the accuracy of FNAC in diagnosis of thyroid swelling and to assess the correlation between preoperative cytological diagnosis and post operative histopathological diagnosis....
A series of 31 consecutive parotidectomies was evaluated. FNAC could differentiate tumour from non tumour in 72.8% of cases. For actual histology, FNAC was correct in 66.6%. Frozen section was correct in differentiating between benign, malignant and inflammatory conditions in all cases. Eighty-eight percent of frozen section histology concurred with final histology. The immediate postoperative ...
