Objective: To evaluate the accuracy of fine needle aspiration cytology (FNAC) in comparison to paraffin section in thyroid swelling. Study design: Cross sectional study. Place and duration of study: Department of Surgery, Bangabandhu Sheikh Mujib Medical University from July 2009 to June 2011. Patient and method: One hundred patients with enlarged thyroid gland of both sexes were selected from admitted patient of Surgery department. All patients had preoperative FNAC, performed by pathologist at the Histopathology department and postoperative specimen were also examined and histopathological diagnosis were made. All FNAC diagnosis were correlated with the histopathological diagnosis. Results: Out of 100 patients 23 were male and 77 were female, male-female ratio 1: 3.3. In FNAC 76 patients were diagnosed as benign lesion of which 8 were later diagnosed as malignant on histopathological examination (68 were true negative 8 were false negative). 22 cases were diagnosed as malignant, both on FNAC and histopathological examination. Only 2 cases were diagnosed as follicular neoplasm on FNAC but on histopathological examination diagnosed as follicular carcinoma (22 cases were true positive) in this study. Overall sensitivity of FNAC were 68.75%, specificity 100.00% and accuracy 90%; PPV=100% & NPV=87.18% Conclusion: FNAC is a reliable, safe and accurate method as a preoperative evaluation in thyroid gland swelling before surgery. FNAC has more accuracy and specificity in detecting thyroid gland malignancy and therefore it is a reliable diagnostic test for evaluating thyroid swellings.

Background: Fine needle aspiration cytology has been shown to be simple, safe, cost effective and quick to perform procedure with excellent patient compliance. It is a well established technique for preoperative investigation of thyroid gland swellings with high sensitivity, specificity and accuracy. The aim of this study was to determine the accuracy of fine needle aspiration cytology of thyroid swellings performed at our institution. Materials and Methods: This study was carried out at Kathmandu Medical College and Teaching hospital, department of Pathology over a period of 3 years (January 2010 to December 2012). Two hundred and seventy three patients of all age groups and both sexes who underwent fine needle aspiration cytology for thyroid swelling were evaluated. Out of 273 patients, histopathological diagnosis was available in 45 patients. Results: Fine needle aspiration cytology result revealed 245 cases (89.7%) as non-neoplastic, 21 cases (7.7%) as neoplastic and 7 cases (2.6%) inadequate due to lack of cellularity. The commonest lesion in the thyroid gland was colloid goiter. Among the malignant neoplasms the commonest was papillary carcinoma. Out of 273 patients, histopathological diagnosis was available in 45 patients. Statistical analysis of our data shows the diagnostic accuracy of fine needle aspiration cytology to be 95.7%. Fine needle aspiration cytology showed a sensitivity of 96.4% and a specificity of 94.4%. Conclusion: Fine needle aspiration cytology is a well established technique for pre operative investigation of thyroid gland swellings with high sensitivity, specificity and accuracy.

ABSTRACT Introduction Though fine needle aspiration cytology (FNAC) for thyroid is acclaimed as a gold standard before going for intervention, there are some limitations with respect to tissue availability, technique, skill of performer, etc. 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 cytopathological diagnosis and postoperative histopathological diagnosis. Materials and methods Data collected from records in the time period of 3 years, i.e., from August 2012 to August 2015, were evaluated and analyzed. Results A total number of 93 cases were included in the study of which majority were females with frequency of 84.94%, most of the incidence of thyroid swellings occur in the age group of 40 to 50 years. Overall mismatch between histopathological examination and FNAC was 43 out of 93 and of which 7 were major and 36 were minor mismatch. Sensitivity of patients having malignancy with positive FNAC is 82.35% from the study and specificity of patients with nonmalignant thyroid disease and positive cytology is 95.18%. Conclusion It was observed that FNAC is a reliable, safe, and accurate method as a first line of evaluation in thyroid swelling before the surgery. Fine needle aspiration cytology is more sensitive in detecting thyroid gland malignancy but still correlation is always necessary and therefore, histopathological analysis still remains essential for final diagnosis.

<b><i>Objectives:</i></b> To determine the role and efficacy of fine needle aspiration cytology (FNAC) and cell block in diagnosis of jaw lesions and compare the agreement between FNAC and cell block to predict the diagnosis. <b><i>Method:</i></b> The sample comprised 51 cases, including 12 odontogenic keratocysts (OKCs), 8 ameloblastomas, 22 radicular cysts, 7 dentigerous cysts, and 1 each of intraosseous mucoepidermoid carcinoma (MEC) and adenomatoid odontogenic tumor (AOT). FNAC samples remaining after hematoxylin and eosin (H&amp;E)-stained cytosmear diagnosis were centrifuged at 3,000 rpm for 10 min. The supernatant was discarded and sediment mixed with 2–3 mL alcohol and filtered. To this, 10% formalin was added, filtered, taken for routine processing, and stained with H&amp;E. The result of FNAC smear and cell block was compared with histopathological diagnosis. <b><i>Results:</i></b> On cytological examination of the smears, 7 OKCs and 22 radicular cysts were diagnosed, whereas ameloblastomas, AOT, intraosseous MEC, and dentigerous cysts were not. This gave an agreement of 56.8% with the biopsy reports. Cell block sections stained with H&amp;E of 12 OKCs, 22 radicular cysts, 1 MEC, and 3 cases of ameloblastoma offered a diagnosis in accordance with the biopsies giving an agreement of 74.5%, while dentigerous cyst and AOT failed to do so. In comparison with FNAC, additionally 5 cases of OKC and 1 of MEC could be detected, and in ameloblastoma, out of 8 cases, only 3 yielded a concordant diagnosis through the cell block technique. <b><i>Conclusion:</i></b> In comparison with FNAC, the architectural pattern and the morphology of the cells were better preserved by the cell block technique. This substantiates that cell block could be used as an ancillary technique to aid in definitive diagnosis of head and neck swellings.

Cysticercosis is a systemic parasitic disease caused by the larval form of cestodeT. solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The patient most commonly presents with subcutaneous and muscle involvement in the form of nodular lesions. The other most commonly involved sites include eye, brain, bladder wall, and heart. Cysticercosis can be diagnosed on serology, and radiologically but confirmatory diagnosis is based on histopathological examination of the involved tissue biopsy specimen. Fine needle aspiration cytology is a useful low-cost outpatient procedure tool for preoperative diagnosis of cysticercosis and is absolutely essential for diagnosis of the parasitic lesions in a peripheral hospital, one like ours.

ABSTRACT Extramedullary noncutaneous plasmacytoma (ENP) is a myeloproliferative disorder of plasma cells that rarely affects cats. This paper describes an ENP case revealed by fine needle aspiration cytology (FNAC) of the mass in the skeletal muscle of an 8-month-old, male, mixed breed cat, which had a nodule in the left hind limb. The rapid immunoassay test confirmed the presence of feline leukemia virus (FeLV). The animal necropsy macroscopically showed the nodule came from the semimembranosus muscle. Histopathological examination ratified the cytological findings. Thus, this paper alerts to the existence of plasmacytoma located in the skeletal muscle of feline species. FNAC is a quick and efficient method for diagnosis of ENP.

Background: Ovarian lesions are quite common among females of all age groups. Ovarian cancers account for 6% of female malignancy. Ultrasonography (USG) can help in proper identification and categorization of these lesions. Fine Needle Aspiration Cytology (FNAC) under USG guidance can be an effective modality for early diagnosis of ovarian masses. Aims And Objectives: To evaluate the role of USG guided FNAC over ovarian space occupying lesions (SOLs) for proper categorization into non-neoplastic, benign & malignant variants and to identify possible underlying causes of cytological misdiagnosis, if any, in comparison to histopathological diagnosis. Materials and Methods: FNAC under USG guidance were performed over one hundred and sixteen cases with radiologically proved ovarian SOLs during a period of five years. Aspirated materials were interpreted as non- neoplastic, benign or malignant lesions. Histopathological study was possible in 47 of these cases. Results: Out of 116 aspirations, non-neoplastic, benign and malignant diagnosis were given in 51, 42 & 23 cases, respectively. During histopathological correlation 41 out of 47 cases (87.2%) show exact cytohistological parity. Rest six cases with cytological misdiagnosis were discussed in detail. Conclusion: USG guided FNAC can effectively diagnose ovarian lesions in more than 87% cases. Scrutiny about failed diagnosis will help to improve accuracy in future.
