Abstract
We reviewed the current status of thyroid fine-needle aspiration cytology (FNAC) in Korea. Thyroid aspiration biopsy was first introduced in Korea in 1977. Currently, radiologists aspirate the thyroid nodule under the guidance of ultrasonography, and cytologic interpretation is only legally approved when a cytopathologist makes the diagnosis. In 2008, eight thyroid-related societies came together to form the Korean Thyroid Association. The Korean Society for Cytopathology and the endocrine pathology study group of the Korean Society for Pathologists have been updating the cytologic diagnostic guidelines. The Bethesda System for Reporting Thyroid Cytopathology was first introduced in 2009, and has been used by up to 94% of institutions by 2016. The average diagnosis rates are as follows for each category: I (12.4%), II (57.9%), III (10.4%), IV (2.9%), V (3.7%), and VI (12.7%). The malignancy rates in surgical cases are as follows for each category: I (28.7%), II (27.8%), III (50.6%), IV (52.3%), V (90.7%), and VI (100.0%). Liquid-based cytology has been used since 2010, and it was utilized by 68% of institutions in 2016. The categorization of thyroid lesions into "atypia of undetermined significance" or "follicular lesion of undetermined significance" is necessary to draw consensus in our society. Immunocytochemistry for galectin-3 and BRAF is used. Additionally, a molecular test for BRAF in thyroid FNACs is actively used. Core biopsies were performed in only 44% of institutions. Even the institutions that perform core biopsies only perform them for less than 3% of all FNACs. However, only 5% of institutions performed core biopsies up to three times more than FNAC.

Abstract
Thyroid tuberculosis is uncommon even in countries like India where prevalence of tuberculosis is high. Bactericidal actions of colloid, excess iodine stores and high vascularity of the gland have been implicated for the very rare occurrence of thyroid tuberculosis. We present a case of a 16-year-old male with thyroid involvement as a part of disseminated tuberculosis. The clinical presentation of thyroid tuberculosis is varied and may be missed if not kept in the differential diagnosis of goitre. This case also highlights the role of fine needle aspiration cytology in management of goitre. It is an important diagnostic test as it avoids unnecessary surgical intervention.

Abstract
Anaplastic Thyroid Carcinoma (ATC) is a relatively uncommon highly malignant tumour originating from the follicular cells of thyroid gland having poor prognosis. It accounts for 2% to 5% of all thyroid carcinomas and patients typically present with a rapidly growing anterior neck mass with aggressive symptoms. A 53-year-old male presented with diffuse neck swelling measuring 8x6 cm and right cervical lymph node measuring 2x2 cm since one month which was associated with dyspepsia and dyspnoea. Ultrasound and Contrast Enhanced Computed Tomography (CECT) neck revealed enlarged right lobe of thyroid and multiple enlarged cervical lymph nodes with soft tissue density nodules in bilateral lungs. Fine Needle Aspiration (FNA) from the swelling revealed giant cell, spindle cell and squamoid pattern. Focal areas showed follicular epithelial cells arranged in repeated microfollicular pattern suggesting an underlying follicular neoplasm. FNAC smears from the lymph node also revealed similar findings. Based on the cytomorphological and radiological findings, final diagnosis of ATC probably arising from underlying follicular carcinoma with cervical lymph node and lung metastasis was given. FNAC leads to prompt and definitive diagnosis, so that therapy can be initiated as soon as possible for better outcome. Multimodality therapy (surgery, external beam radiation, and chemotherapy) is the mainstay of treatment.

Abstract
Primary cutaneous aspergillosis is a rare disease, caused by organisms like Aspergillus flavus and Aspergillus fumigatus. Fine Needle Aspiration Cytology (FNAC) is a simple and well established tool for the diagnosis of mycotic infections. We report a case of forearm swelling that presented clinically as lipoma in a known case of lepromatous leprosy. It was diagnosed as primary cutaneous aspergillosis on FNAC, which was subsequently confirmed on culture. Cutaneous aspergillosis co-existing with leprosy has rarely been reported in the literature and early diagnosis of aspergillosis in immunocompromised patients is mandatory.

Abstract
BACKGROUND Isolated tuberculosis of the spleen has been described occasionally in literature, mostly in immunosuppressed individuals with various risk factors. Sequestration in the spleen makes such Mycobacterium tuberculosis infection difficult to diagnose. This report describes an extremely rare case of isolated splenic tuberculosis in an immunocompetent individual. CASE PRESENTATION A 26 year old Kenyan male presented with pyrexia of unknown origin, with negative screening tests for bacterial, fungal and parasitic infections. Ziehl-Neelsen staining and GeneXpert tests were negative for M. tuberculosis. Diagnosis of isolated splenic tuberculosis was made on core biopsy of the spleen. The patient initially worsened upon treatment with antituberculous medication attributable to the 'Paradoxical Reaction' phenomenon, before making full recovery. CONCLUSIONS This case highlights the need to continuously be on the lookout for tuberculosis especially in unusual presentations, including subsequent paradoxical reaction which may be encountered.

Abstract
BACKGROUND Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells"). CONCLUSION Although the presence of ladybird cells has been described in tissue sections of TSGCT, their identification in cytological specimens has not been reported to our knowledge. When observed, their presence may aid in differentiating TSGCT from other lesions with multinucleated osteoclast-type giant cells occurring at or near joints.

Abstract
INTRODUCTION Need for minimal turnaround time for assessing Fine Needle Aspiration Cytology (FNAC) has encouraged innovations in staining techniques that require lesser staining time with unequivocal cell morphology. The standard protocol for conventional Papanicolaou (PAP) stain requires about 40 minutes. To overcome this, Ultrafast Papanicolaou (UFP) stain was introduced which reduces staining time to 90 seconds and also enhances the quality. However, reagents required for this were not easily available hence, Modified Ultrafast Papanicolaou (MUFP) stain was introduced subsequently. AIM To assess the efficacy of MUFP staining by comparing the quality of MUFP stain with conventional PAP stain. MATERIALS AND METHODS FNAC procedure was performed by using 10 ml disposable syringe and 22-23 G needle. Total 131 FNAC cases were studied which were lymph node (30), thyroid (38), breast (22), skin and soft tissue (24), salivary gland (11) and visceral organs (6). Two smears were prepared and stained by MUFP and conventional PAP stain. Scores were given on four parameters: background of smears, overall staining pattern, cell morphology and nuclear staining. Quality Index (QI) was calculated from ratio of total score achieved to maximum score possible. Statistical analysis using chi square test was applied to each of the four parameters before obtaining the QI in both stains. Students t-test was applied to evaluate the efficacy of MUFP in comparison with conventional PAP stain. RESULTS The QI of MUFP for thyroid, breast, lymph node, skin and soft tissue, salivary gland and visceral organs was 0.89, 0.85, 0.89, 0.83, 0.92, and 0.78 respectively. Compared to conventional PAP stain QI of MUFP smears was better in all except visceral organ cases and was statistically significant. MUFP showed clear red blood cell background, transparent cytoplasm and crisp nuclear features. CONCLUSION MUFP is fast, reliable and can be done with locally available reagents with unequivocal morphology which is the need of the hour for a cytopathology set-up.

Abstract
Salivary gland cytopathology is a diagnostically challenging area with overlapping cytomorphological features between benign, malignant, and metastatic tumors. We report the case of 45-year-old male who presented with two swellings in right retroauricular and infraauricular region along with a palpable single right cervical lymph node. On ultrasonography of the neck, a possibility of malignant lesion was given. Contrast enhanced computed tomography of the head showed a large well-defined space occupying lesion in right temporooccipital region eroding the skull bone with both extra and intracranial extension. Fine needle aspiration was performed from both swellings and cervical lymph node. Based on cytological features and clinicoradiological examination, a possibility of metastasis from epithelial malignancy (adenocarcinoma) was suggested. The retroauricular region swelling was excised, and a diagnosis of salivary duct carcinoma was given on histopathology. In this article, we discuss the diverse presentation, cytomorphological features, and differential diagnosis of this rare salivary gland tumor.

Abstract
Introduction: Hepatitis B virus (HBV) infection is an established cause of hepatocellular carcinoma (HCC) and is associated with poor prognosis. High HBV deoxyribonucleic acid (DNA) load has been identified in HCC and hepatitis B surface antigen-positive patients. Materials and methods: This study was done in the Department of Hepatology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, from January 2006 to December 2007. Thirty patients with HBV infection-related HCC were enrolled. Another 30 patients with HBV-related liver diseases without HCC were analyzed as controls. Results: The HCC patients had a high viral load (>105 copies/mL), while all of the controls had low (<105 copies/mL) viral load. Conclusion: It seems that patients with HCC bear high HBV DNA loads in Bangladesh, but the causes underlying this remain to be resolved.

Abstract
Introduction: Cytologic features of papillary thyroid carcinoma (PTC) have been extensively documented in literature. However, PTC variants can prove to be diagnostically challenging on fine needle aspiration cytology (FNAC). Aims: To study the FNAC features of PTC and its variants and explore the causes for misdiagnosis. Materials and Methods: This is a retrospective study. All cases of histopathologically (HP) confirmed cases of PTC during a 2-year period (January 2012 to December 2013) with presurgical FNAC were included. The cytologic findings and FNAC diagnosis of each case were documented and compared with the HP report. The misdiagnosed cases were reviewed to look for any cytological clues and reasons for misdiagnosis. Results: A total of 58 cases were included. The overall diagnostic accuracy was 55.6% which improved to 64.8% on including suspicious for PTC cases. Follicular variant was the most misdiagnosed variant; 41.2% of the cases were called follicular neoplasm. Oncocytic variant showed cells with abundant eosinophilic cytoplasm along with bizarre giant cells. Warthin tumor-like variant showed cells with moderate eosinophilic cytoplasm with close apposition of lymphocytes in a background of reactive lymphocytes and lymphoid tangles. Cystic variant was paucicellular. Columnar cell variant showed tall columnar cells with nuclear stratification. Cribriform–morular variant showed syncytial sheets of cells and hyaline globules. Conclusions: PTC variants have distinct cytomorphological features. In some variants (follicular, columnar cell), nuclear grooves and inclusions may not be apparent, contributing to the diagnostic confusion. Benign nodule adjacent to the tumor can dominate the FNAC smear and lead to misdiagnosis.

Abstract
Introduction: Ultrafast Papanicolaou stain (UFP) was introduced as a hybrid of Romanowsky and Papanicolaou (PAP) stain. It enhances the quality and reduces the time. In the present study, a modified staining technique was adapted where Gill's Hematoxylin was replaced by Harris Hematoxylin. Aims: The aim of the study was to assess the use of the modified ultrafast Papanicolaou (MUFP) stain for fine needle aspiration cytology (FNAC) of head and neck swellings in comparison with the routine PAP stain, hematoxylin and eosin (H and E), and Giemsa. Materials and Methods: Forty FNACs of head and neck swellings were collected. FNAC procedure was performed by standard method; two smears were fixed in 95% propanol and stained with PAP and H and E. Two smears were air dried, 1 was stained with Giemsa, and 1 was rehydrated with normal saline, fixed in alcoholic formalin, and stained with MUFP. Four parameters were considered and scored background, cell morphology, nuclear staining, and overall staining pattern). Results: The quality of MUFP smears were better when compared to routine PAP, H and E, and Giemsa, and was statistically significant by Wilcoxon matched pair test. Conclusions: MUFP stain in comparison to routine PAP, H and E, and Giemsa provides an excellent and suitable alterative in cytological staining for the study of various organs.

Abstract
This study evaluates the combined role of axillary ultrasound, fine needle aspiration cytology and sentinel lymph node biopsy in clinically N0 axilla. Between January 2014 and June 2015, 150 women with early breast cancer underwent axillary ultrasound as a first investigation for nodal status. Suspicious nodes were subjected to image guided fine needle aspiration cytology. Non-suspicious and fine needle aspiration cytology negative axillary nodes proceeded to sentinel lymph node biopsy at time of primary breast surgery. All confirmed positive (cytology and frozen) cases proceeded to axillary lymph node dissection. 52 women had positive axillary nodes at final histology. Axillary ultrasound with fine needle aspiration cytology identified 27 patients with positive axillary nodal status and had a sensitivity of 84.36 % (27/32) and specificity of 87.5 % (14/16). Intraoperative frozen analysis identified a further 13 cases with sensitivity of 56.52 % (13/23) and specificity of 97.56 % (80/82). Overall 76.92 % (40/52) patients with positive axillary metastasis were identified peri-operatively using combination of axillary ultrasound, cytology and sentinel lymph node biopsy.

Abstract
Diagnosis of thyroid by fine needle aspiration is challenging for the "indeterminate" category and can be supported by molecular testing. We set out to identify miRNA markers that could be used in a diagnostic setting to improve the discrimination of mutation-negative indeterminate fine needle aspirations. miRNA high-throughput sequencing was performed for freshly frozen tissue samples of 19 RAS and PAX8/PPARG mutation-negative follicular thyroid carcinomas, and 23 RAS and PAX8/PPARG mutation-negative follicular adenomas. Differentially expressed miRNAs were validated by quantitative polymerase chain reaction in a set of 44 fine needle aspiration samples representing 24 follicular thyroid carcinomas and 20 follicular adenomas. Twenty-six miRNAs characterized by a significant differential expression between follicular thyroid carcinomas and follicular adenomas were identified. Nevertheless, since no single miRNA had satisfactory predictive power, classifiers comprising two differentially expressed miRNAs were designed with the aim to improve the classification. Six two-miRNA classifiers were established and quantitative polymerase chain reaction validated in fine needle aspiration samples. Four out of six classifiers were characterized by a high specificity (≥94 %). The best two-miRNA classifier (miR-484/miR-148b-3p) identified thyroid malignancy with a sensitivity of 89 % and a specificity of 87 %. The high-throughput sequencing allowed the identification of subtle differences in the miRNA expression profiles of follicular thyroid carcinomas and follicular adenomas. While none of the differentially expressed miRNAs could be used as a stand-alone malignancy marker, the validation results for two-miRNA classifiers in an independent set of fine needle aspirations are very promising. The ultimate evaluation of these classifiers for their capability of discriminating mutation-negative indeterminate fine needle aspirations will require the evaluation of a sufficiently large number of fine needle aspirations with histological confirmation.

Abstract
Odontogenic Myxoma (OM) is a slow growing painless locally aggressive tumor seen in gnathic bones and is generally asymptomatic. OM is characterized by spindle, wedge or stellate shaped cells loosely arranged in an abundant mucoid stroma. It is found incidentally on radiographs and may vary from a unilocular radiolucency to a multilocular lesion with well-defined or diffuse margins. Treatment includes surgical management that may range from simple enucleation and curettage to surgical excision including peripheral osteotomy, segmental resection, hemimandibulectomy and maxillectomy. Here we are presenting a case report on odontogenic myxoma with recurrence after conservative treatment.

Abstract
Cervical lymphadenopathy is one of the commonest presenting complaint of patient in ENT OPD Fine Needle Aspiration Cytology (FNAC) is one of the most reliable, less expensive, and basic diagnostic procedure for the definitive and conclusive diagnosis for the immune system which reciprocates in the form of enlarged lymph nodes. A study was conducted in ENT Department of Santosh Medical College, Ghazibad from August 2015 to May 2016 on 64 patients with enlarged cervical lymph nodes. FNAC was done to make the diagnosis. Out of 64 patients (51.5 %) was reactive non-specific, 28 % tubercular, 3.1 % lymphoma and 17 % were malignant. FNAC is one of the most dependable diagnostic tools in case of cervical lymphadenopathy for early diagnosis and detection for the better management.

Abstract
Acinic Cell Carcinoma (AcCC) is a slow growing, malignant tumour of salivary glands, predominantly found in parotid gland and rarely in submandibular gland or minor salivary glands. Rarely, the tumour can arise in Heterotopic Salivary Gland Tissue (HSGT) and can present bilaterally. Synchronous contralateral tumour or tumour arising in HSGT is easily missed clinically. Fine Needle Aspiration Cytology (FNAC) is an important preoperative diagnostic investigation in cases of AcCC. Sometimes its diagnosis on cytology is very difficult and it is easily misdiagnosed as benign, affecting the long term prognosis. Here, we present two unusual cases of AcCC. One developed in HSGT and the other was synchronous bilateral. Though the histological features of AcCC appear to be characteristic but clinical suspicion and cytological features have been described as equally important for preoperative diagnosis. Present cases highlight the importance of a cytopathologist who plays an important role in its preliminary diagnosis.

Abstract
Background Due to therapeutic implications with regard to both efficiency and safety of chemotherapy agents it is important to differentiate between subtypes of NSCLC. Up to today we experience a continuous reservation regarding the use of fine needle aspiration cytology. The aim of the present study is to estimate the value of cytologic criteria for lung cancer typing on small biopsies independent from all possible technique failures. Methods Between January 1997 and December 2008 760 intraoperative FNAC- (fine needle aspiration cytology) specimens from 702 patients have been examined. Cytologic evaluation and immediate communication of results to the surgeons followed. Afterwards, intraoperative cytologic findings were compared with final histologic diagnoses of the resected specimens. Results Intraoperative cytologic analysis yielded a sensitivity of 94.8 %, a specificity of 98.8 %. An overall positive predictive value of 99.8 % with respect to final histologic analysis of primary lung cancer was achieved. The highest value could be reached for adenocarcinomas, followed by carcinoids and squamous cell carcinomas. Conclusions Lung cancer typing according to cytologic criteria is feasible and accurate as well as comparable with results of histologic analysis on small specimens. Herewith, clinicians can come up to the increasing demands on minimally invasive harvested specimens with regard to therapeutic implications.

Abstract
Definitive diagnosis of parotid gland masses is required optimal management planning and for prognosis. There is controversy over whether fine needle aspiration cytology (FNAC) or ultrasound guided core biopsy (USCB) should be the standard for obtaining a biopsy. The aim of this review is to assess the current evidence available to assess the benefits of each technique and also to assess the use of intra-operative frozen section (IOFS). Literature searches were performed using pubmed and google scholar. The literature has been reviewed and the evidence is presented. FNAC is an accepted and widely used technique. It has been shown to have variable diagnostic capabilities depending on centres and experience of staff. USCB has a highly consistent diagnostic accuracy and can help with tumour grading and staging. However, the technique is more invasive and there is a question regarding potential for seeding. Furthermore, USCB is less likely to be offered as part of a one-stop clinic. IOFS has no role as a first line diagnostic technique but may be reserved as an adjunct or for lesions not amenable to percutaneous biopsy. On balance, USCB seems to be the method of choice. The current evidence suggests it has superior diagnostic potential and is safe. With time, USCB is likely to supplant FNAC as the biopsy technique of choice, replicating that which has occurred already in other areas of medicine such a breast practice.

Abstract
BACKGROUND AND AIMS The cytologic patterns of lymph node fine needle aspirations (FNAs) exhibit a wide variation in different diseases and in different ethnic groups in various geographical locations. Knowledge of lymphadenopathy patterns in a given geographical region is essential for making a confident diagnosis of suspected disease in that location. In the present study, we assessed the cytologic patterns of lymph node aspirations in patients in the Huangdao region of China. METHODS A three-year retrospective study design was conducted on FNA cytology samples from the lymph nodes of patients in our hospital between January 2011 and December 2014. RESULTS A total of 2136 lymph nodes were aspirated during the study period. Cytologic analysis of the lymph nodes revealed the following: malignancy, 53.6%; chronic non-specific lymphadenitis, 15.2%; reactive lymph node, 7.5%; pyogenic abscess, 2.9%; tuberculosis lymphadenitis, 8.7%; Hodgkin lymphoma, 4.8%; and non-Hodgkin lymphoma, 7.16%. The 30-50 year age group was the most affected age group, while lymphadenopathy in the >60 year age group was less frequent. Cervical lymph nodes were the most frequent site for lymphadenopathy in women (31.4%, p < 0.001) and men (49.1%, p < 0.001). CONCLUSIONS Lymphadenopathy is associated with a wide range of disorders; however, metastatic lymph nodes of malignancies are the most common cause for enlarged lymph nodes.

Abstract
INTRODUCTION Fine Needle Aspiration (FNA) of space occupying lesions in superficial or deep anatomic sites is an increasingly common procedure, providing rapid and safe diagnosis. However, sometimes FNA does not yield sufficient information for a precise diagnosis and the risk of false negatives and indeterminate diagnosis is always present. Therefore, we attempted to obtain additional information via the preparation of Cell Block (CB) from the residual material of aspirates and thus enhance the diagnostic accuracy. AIM This study was carried out to evaluate the role of CB as a useful adjunct to smears for establishing a more definitive cytopathologic diagnosis and for its utility in special staining and Immuno-histochemistry (IHC). MATERIALS AND METHODS A total of 66 cases of image-guided FNA of abdominal masses were studied. In addition to the routine smears, CBs were prepared from the residual tissues for all possible cases and its diagnostic efficacy was analysed. Further, the use of CBs for special staining and IHC was also established. RESULTS This study included a total of 66 patients with abdominal masses who were referred for guided FNA cytology. Out of these cases, adequate material was obtained on FNAC in 64 cases (96.96%) and on CB in 45 cases (68.18%) and the diagnosis was provided. There was a good agreement between the FNA smear diagnosis and CB diagnosis. The histopathology of CB sections further helped in precise final cytopathological diagnosis. Two FNA smears were unsatisfactory for evaluation and hence the diagnosis was done on CB sections alone. With FNA cytology and CB in combination, a cytopathological diagnosis was given for all the 66 cases. The sensitivity of FNA in comparison to the histopathology of CB was 91.6% and specificity was 88.8%. The diagnostic accuracy was 62% and the discordance was 6%. CONCLUSIONS CB in addition to the routine FNA is a simple, reliable and cost-effective technique that further contributes to the final cytopathological diagnosis.

Abstract
Objective To summarise the role of fine needle aspiration cytology in the differential diagnosis of vascular anomalies from other lesions in the head and neck region by presenting five interesting cases reported from our hospital data. Method Five patients ranging in age from 3 months to 25 years old were diagnosed with vascular anomalies based on their histories, clinical examinations, imaging examinations and ultrasonic testing. The previous diagnosis of these patients were corrected by fine needle aspiration cytology in our hospital and the proper treatment was administered. Result Two cases were wrongly treated in a local hospital. All five of the patients underwent operations after excluding vascular anomalies by fine needle aspiration cytology. Conclusion Fine needle aspiration cytology should be used in the following situations to prevent misdiagnoses and the mistreatment as vascular anomalies: when imaging examination and ultrasonic testing lead to a diagnosis of vascular malformation, but the history or clinical examination does not confirm this diagnosis; when lesions are treated as "vascular malformations" by sclerotherapy, and the hydatid fluid is not like blood or lymph fluid; and when propranolol is used to treat the proliferation stage of "haemangiomas" with without any effect.

Abstract
Filariasis is a major health problem in tropical countries, including India. The disease is endemic all over India, especially in Uttar Pradesh, Andhra Pradesh, Orissa, Bihar, Jharkhand, Tamil Nadu, Kerala, and Gujarat. A heavy parasitic load may appear in the blood, urine with chyle, and at times in scrotal aspirates. It is very unusual to find microfilaria in thyroid aspirate. Here, we present a rare case in which microfilaria was found during fine needle aspiration cytology of a solitary thyroid nodule.

Abstract
Testicular tuberculosis (TB) is a rare form of genitourinary TB. It is usually presented as painful or painless testicular swelling with or without scrotal ulceration or discharging sinus. Infertility may occur. Epididymal involvement is usually seen in testicular TB. In most cases, genital TB is associated with TB involvement of kidneys or lower urinary tract. Ultrasound (USG) and USG-guided fine needle aspiration cytology of testicular swelling confirm the diagnosis. Anti-TB chemotherapy is the mainstay of treatment to ensure the complete resolution of the lesion. However, in very few cases, orchidectomy is required for both diagnosis and treatment. Here, we report a very rare case of left sided isolated testicular TB in a 20-year-old male who was completely cured with 6 months regimen of anti-TB chemotherapy.
