Abstract
INTRODUCTION Owing to certain inherent limitations of earlier reporting systems, "The Paris System for Reporting Urinary Cytology (TPS)" was implemented in 2015 to standardize reporting urine cytology with more stringent cytomorphologic criteria. We share our post-TPS experience, comparing it with the conventional system (CS). AIM To assess and compare the cyto-histopathologic/cystoscopic agreement between the conventional and the Paris systems (CS and TPS) for reporting urine cytology. MATERIALS AND METHODS It is a cross-sectional study involving urine samples from 170 patients divided into two groups (CS and TPS). Of the 170 cases, 85 were reported according to the CS, and 85 were reported according to TPS with all the relevant clinical, radiologic, and cystoscopic findings. Using the kappa statistics, both groups were statistically analyzed for sensitivity, specificity, predictive values, and agreement. RESULTS The sensitivity and specificity for high-grade urothelial carcinoma (HGUC) as per TPS were 83.33% and 94.59%, respectively, while they were 73.47% and 80.56% for the conventional system. The agreement for HGUC with TPS was 87.06% with a kappa value of 0.7416, while it was 76.5% with a kappa value of 0.53 for the CS. Implementing the TPS minimized usage of the atypical urothelial cells (AUC) category, increasing the clarity in detecting HGUC. CONCLUSION TPS provides better agreement with histopathology than the CS for diagnosing HGUC, which is attributable to stringent TPS criteria that prompt cytopathologists to look more diligently for morphologic and numeric criteria.

Abstract
BACKGROUND Burkitt lymphoma (BL) is an aggressive high-grade B-cell non-Hodgkin lymphoma commonly diagnosed in young age and is known to involve extra nodal sites. But the involvement of body fluids by BL is an uncommon presentation. Rapid diagnosis of BL is vital to prevent complications like tumour lysis syndrome. Cytological examination of body fluids continues to be an indispensable tool for rapid diagnosis of BL. OBJECTIVES In this study, we aim to study the clinical, cytomorphological and immunophenotypic characteristics of BL involving serous effusions and other fluids. MATERIALS AND METHODS In this retrospective study, 17 cases reported as BL in fluid cytology from 2016 to 2022 were collected and reviewed. We performed a comprehensive analysis of the clinical data, cytomorphological features, immunophenotyping data along with the haematological workup of these cases. We have also compared with the histopathological diagnosis for those cases where biopsy was available. RESULTS BL more commonly involved ascitic fluid (52%), followed by pleural fluid (4 cases) and cerebrospinal fluid (CSF; 4 cases). Primary diagnosis of BL in fluid was done in 88% of the cases. Bone marrow involvement was noted in two cases. Cytological smears showed discrete monomorphous population of medium-sized atypical lymphoid cells with frequent apoptotic bodies. Classic cytoplasmic punched out vacuoles were observed in 88% of the cases. Immunophenotyping data was available for 12 cases in which tumour cells showed positivity for CD20 (100%), CD10 (4 of 7 cases), BCL6 (3 of 5 cases) and cMYC (7 of 7 cases-100%) and were negative for Terminal deoxynucleotidyl transferase (TdT) (11 of 11 cases). Mean Ki67 labelling index was 95%. Histopathological diagnosis was available for 9 cases, and there was 100% agreement between cytological and histopathological diagnosis in 7 cases. CONCLUSION Precise diagnosis of BL can be rendered in body fluids by identification of classic cytomorphological features and by performing supportive ancillary tests in fluids for immunophenotyping.

Abstract
Background Follicular-patterned lesions are a major gray zone in thyroid cytopathology. The recently introduced 2022 World Health Organization (WHO) classification emphasizes the importance of genetic alterations in thyroid neoplasms with the introduction of certain newer terminologies that are expected to cause remarkable changes in cytopathologic and histopathologic reporting. Although molecular assays such as the Afirma gene expression classifier and the ThyroSeq are already in use, there has been an ongoing search for further reliable molecular markers. The growth differentiation factor-15 (GDF-15) is one among them. This study aimed to determine the diagnostic utility of GDF-15 mRNA expression in frozen tissue and fine-needle aspiration (FNA) samples from follicular-patterned thyroid lesions and neoplasms. Methodology The real-time quantitative polymerase chain reaction was performed on 75 frozen tissue and FNA samples each from 19 cases of follicular thyroid hyperplasia (FTH), 10 nodular goiters (NGs), 17 follicular thyroid adenomas (FTAs), eight follicular thyroid carcinomas (FTCs), 12 follicular variant of papillary thyroid carcinomas (FVPTCs), and nine classic papillary thyroid carcinomas (CPTCs) that were diagnosed according to the 2017 WHO classification of thyroid neoplasms. The GDF-15 mRNA expression in all these cases was assessed and compared with the control thyroid tissue samples. One-way analysis of variance and the Kruskal-Wallis test were performed using GraphPad Prism 8 software to determine the significance of differences in the GDF-15 mRNA levels among various thyroid lesions. Results A higher GDF-15 mRNA expression was noted in the malignant thyroid neoplasms including FTC, FVPTC, and CPTC in comparison to FTA, with a fold change between the malignant and benign groups being more than 244.18 times. A difference in the fold change was noted between FTH and FTA with an increase in GDF-15 mRNA level in the latter, which was statistically not significant. Conclusions The fact that GDF-15 mRNA was studied both on fine-needle aspiration cytologic and the frozen tissue material and that the majority of the lesions studied were follicular-patterned establishes the GDF-15 as a potential marker not only for diagnosing malignant thyroid neoplasms of the follicular epithelium but also in distinguishing benign and malignant follicular-patterned neoplasms of the thyroid.

Abstract
Background Tuberculous effusions are common. Classically, they are described as bacteria poor and lymphocyte rich. Our experience, however, has been more varied. We compiled this rare group of bacteria-positive tuberculous fluids to document their cytologic spectrum and to look for possible predictors of bacillary positivity. Methods Fifty-one cases of bacillary positive fluids were identified and their clinicopathological details were noted. Per case, the smear background was assigned as either clear, caseous, suppurative, granular proteinaceous or frankly hemorrhagic. Fine, punched-out vacuoles in the smear background were also noted. The bacillary load in each case was classified from scanty to 3+. Eventually, the clinicopathologic variables were tabulated for frequency and studied for any association with bacillary presence. Results Only 19 of the 51 patients had a history of tuberculosis. Retropositive patients comprised a small proportion (9.8%) and did not always indicate strong (3+) bacillary positivity. The granular proteinaceous background was the most frequent (35%) pattern. Only a suppurative background was associated with strong bacillary positivity. Fine vacuoles were seen almost always with caseous and granular proteinaceous backgrounds but without statistical significance. Conclusion Tuberculous effusions can have diverse smear backgrounds, not necessarily one rich in caseous material. When tuberculosis is known or clinically suspected, non-classical findings such as abundant neutrophils or suppurative background should not dissuade one from requisitioning mycobacterial stains. In fact, acid-fast stains should probably routinely accompany Giemsa slides of clinically idiopathic effusions in endemic areas since it is still the cheapest and fastest method for a conclusive diagnosis.

Abstract
Rhinosporidium seeberi belongs to the eukaryotic class Mesomycetozoea and causes chronic granulomatous lesions known as rhinosporidiosis. Rhinosporidiosis frequently involves the nasal cavity and nasopharynx through transepithelial invasion. Atypical presentations of this disease at other body sites have been reported, including the subcutis, visceral organs, bones, and genitals. Only a few cases of cutaneous and subcutaneous involvement have been reported to date. This chronic granulomatous condition is known for its recurrence following autoinoculation unless the correct diagnosis and appropriate treatment are given. We describe a case of an immunocompetent adult who had undergone fine needle aspiration cytology (FNAC) of mass-like swellings in the right thigh and right calf at another healthcare centre and had been diagnosed with a small round blue cell tumour. FNAC at our centre confirmed a rare case of rhinosporidiosis that was clinically mimicking a soft tissue neoplasm of the lower extremity, and the erroneous interpretation of the prior cytology studies had resulted in misinterpretation of the individually dispersed pathogenic organisms as individual malignant cells. FNAC of rhinosporidiosis can lead to early diagnosis and prompt treatment of this pathogen when it presents at unanticipated body sites.

Abstract
Introduction: Detection of malignant cells in cerebrospinal fluid (CSF) samples in suspected cases of malignancy is critical for the management of patients. CSF involvement by nonhaematolymphoid malignancies is less common. We aimed to study the cytomorphologic characteristics of various nonhaematolymphoid malignancies in CSF. Methods: A retrospective cytomorphological analysis of 27 CSF cytology smears reported as positive or suspicious for nonhematolymphoid malignancies from January 2010 to April 2020 over 10 years was carried out. Smears in all cases were prepared by cytospin technique and stained with May-Grunwald-Giemsa (MGG) and papanicolaou (Pap) staining procedures. Cell immunohistochemistry/immunocytochemistry was done wherever cell block/extra slides were available. Results: Twenty-four of 27 cases were interpreted as “positive,” while three were reported as “suspicious” of malignancy. Nineteen of 27 cases were metastatic adenocarcinomas including three suspicious malignancy cases with the primary sites of origin being the breast (10), stomach (2), rectum (1), gall bladder (1), lung (1), and four cases of unknown primary. Of the remaining positive cases, there were five cases of metastatic medulloblastoma, two cases of metastatic pineoblastomas, and one case of metastatic extraskeletal Ewings sarcoma. Each of these metastatic malignancies had at least a single diagnostic cytomorphological clue, similar to those observed in other body cavities and primary malignancy sites. Conclusion: Nonhematolymphoid malignancies are readily diagnosable on CSF cytology, most of them are metastatic. Identification of malignant cells in CSF is critical, as it has therapeutic and prognostic implications.

Abstract
Background: Effusions as part of hematologic neoplasms are rare and as a primary presentation, rarer. In standalone laboratories of developing countries, resorting to techniques such as flow cytometry or immunohisto/cytochemistry may not be possible. A near definitive diagnosis on cytomorphology would, therefore, be an ideal beginning. To that end, we compiled our cases of primary hematolymphoid effusions, devising reproducible reporting categories and looked at their concordance with the final histopathology. Subjects and Methods: Fifty-four cases of primary hematolymphoid effusions over 10 years with cytology-histopathology correlation were chosen. Post morphology assessment, the cases were organized into six categories: suspicious of hematolymphoid malignancy, non-Hodgkin lymphoma-high-grade (NHL-HG), low-grade NHL (NHL-LG), Burkitt lymphoma, acute leukemias, and plasma cell dyscrasias. Discordance with histology was assigned as major and minor based mainly on therapeutic implications. Results: Concordance was seen in a good number (81.5%) of cases. The NHL-HG and NHL-LG categories contributed to 33.3% each of major discordance. Tuberculosis and epithelial malignancies comprised the bulk of the major discordance. Overdiagnosis of a high-grade lymphoma for a histologically proven low-grade follicular lymphoma was the only case with minor discordance. Conclusion: The cytologic categories used are not foolproof for hematologic neoplasms but have a fairly good concordance. A scanty abnormal population should always be viewed with suspicion and definitive labels should be avoided. While morphologic examination is fraught with danger, a good assessment directs the judicious selection of ancillary methods, and hence cannot be supplanted.

Abstract
BACKGROUND Cytomorphologic distinction of hepatocellular carcinoma (HCC) from its mimics on fine-needle aspiration cytology (FNAC) is often problematic. The present study evaluates the strength of cytomorphology and the utility of an immuno-panel of arginase-1, glypican-3, HepPar-1, thyroid transcription factor (TTF-1) and CK-19 in resolving this diagnostic issue. METHODS FNAC features of 71 nodular hepatic lesions were studied with an immunocyto/ histochemical (ICC/IHC) panel of arginase-1, glypican-3, HepPar-1, TTF-1 taking 10% positivity as "cut-off." Cytomorpholologic diagnoses were compared with diagnoses made on combined cytomorphologic and ICC/IHC approach. RESULTS Of 71 cases, 32, 10 and 29 had histopathologic, cell block and clinico-radiologic correlation respectively with 55 metastatic adenocarcinomas (MAC), 13 HCCs and one case each of hepatic adenoma (HA), cirrhotic nodule (CN) and intrahepatic cholangiocarcinoma (CC). Cytoplasmic positivity of HepPar-1 and glypican-3 were noted in 11/13 and 8/13 HCCs respectively; while only 3/13 and 1/13 HCCs revealed cytoplasmic positivity for arginase-1 and TTF-1 respectively. Benign hepatic lesions were negative for glypican-3 and TTF-1, but expressed both arginase-1and HepPar-1. Twenty-one of 55 MACs and the lone case of CC were positive for CK-19; however, all MACs and CC cases were negative for HepPar-1, arginase-1, glypican-3 and TTF-1. The immune-panel had sensitivity, specificity and diagnostic accuracy of 100%, 88.9% and 90.6%, respectively, for differentiating HCC from its morphologic mimics. CONCLUSION Though a meticulous cytologic evaluation in conjunction with clinicoradiologic profile helps in distinguishing HCC from its benign and malignant mimics; an immunopanel of arginase-1, glypican-3, HepPar-1, TTF-1 and CK-19 drastically improves the diagnostic accuracy.

Abstract
Phyllodes tumor (PT) accounts for less than 1% of all primary tumors of the breast and 2% to 3% of all fibroepithelial lesions. We report a case of heterologous liposarcomatous elements in a malignant PT of the breast on Fine needle aspiration cytology (FNAC) and later confirmed by histopathological examination. A 58-years-old woman presented with a huge breast mass for which FNAC was done. Cytology showed features of malignant PT with a good representation of heterologous liposarcomatous areas. The cytological findings were in concordance with the histologic features. Malignant PT and its various heterologous elements of stroma can be diagnosed on FNA cytology when performed optimally. They can be vital for the preoperative assessment of patients suspected with malignancy to formulate the surgical plan accordingly.

Abstract
BACKGROUND Orbital hematolymphoid lesions are rare and usually encountered in elderly patients. Orbital lesions are not easy to biopsy: hence fine needle aspiration cytology (FNAC) can be a very good diagnostic modality for these lesions. MATERIALS AND METHODS Cases of orbital masses subjected to FNAC dating from 2013 to 2020 were retrieved from our archives. A total of 16 cases with biopsy confirmation were included. All clinical details, the type of procedure, details of the immunocytochemistry (ICC) performed on smear, follow-up biopsy, and their haematological work-up were analysed in detail. RESULTS Sixteen biopsy-confirmed cases had been diagnosed as orbital haematolymphoid lesions on cytomorphology and further categorised with ancillary studies including ICC. In twelve instances, the cytology impression was congruent with the histopathological diagnosis and eight of the sixteen cases (50%) proved to be primary orbital lymphoma. Four were secondary orbital lymphomas and the remaining four included one case each of plasmacytoma, myeloid sarcoma, Rosai-Dorfman disease and angiolymphoid hyperplasia with eosinophilia. CONCLUSION FNAC is a minimally invasive procedure for diagnosing most of the haematolymphoid orbital lesions and it has a rapid turnaround time. The accuracy of cytomorphology combined with ICC on smears/cell blocks can be as good as a biopsy for exact categorisation. Additionally, aspirate smears are preferred samples for cytogenetics compared to formalin-fixed tissue blocks, as molecular cytogenetics techniques are frequently employed for diagnostic, prognostic, and therapeutic purposes.

Abstract
Embryonal rhabdomyosarcoma (ERMS) is a malignant small blue round cell tumor which is commonly seen in head and neck region. Breast and pleural involvement are uncommon. Rhabdomyosarcoma has been rarely reported in the body fluids like ascitic, pleural, and cerebrospinal fluid. In this article, we report an interesting case of ERMS which had deceptive small blue round cells in pleural fluid. The cytomorphological features along with a panel of immunocytochemical markers helped in arriving at the definite diagnosis. Later, biopsy from the breast lump and retroperitoneal mass also revealed the same tumor. This case is reported since it is rare to find sarcoma cells in pleural fluid and highlight the diagnostic difficulties faced during interpretation.

Abstract
INTRODUCTION Conventional cell blocks (CCB) prepared from cytological specimens are very useful but the method is relatively time-consuming. Suitable modifications in cell-block techniques are beneficial for improving the turnaround time. We share our experience of a rapid microwave cell-block (MCB) technique. AIM AND OBJECTIVES To study the quality of routine and immunohistochemical (IHC) staining of cell-block sections from serous body fluids prepared by the MCB technique compared with the CCB technique. METHOD A total of 177 serous body fluid samples were processed by routine centrifugation technique, and the sediments were used for cell-block preparations by both conventional and rapid microwave methods. Cell-block sections were stained with haematoxylin and eosin stain. Haematoxylin and eosin staining quality was analysed using three parameters (cellularity, morphology and staining intensity). IHC for epithelial membrane antigen and calretinin were also performed, and the quality of staining was evaluated on 62/177 samples. Results were analysed using appropriate statistical tests. RESULTS The time taken for processing cell blocks by the MCB method was 1 hour and 18 minutes compared to 13 hours and 45 minutes by CCB. The quality of sections by both methods showed good agreement for cellularity and intensity of staining, and moderate agreement for morphology. A 100% concordance was noted for distinguishing benign and malignant samples on morphology as well as with IHC stain results. CONCLUSION Although the techniques are comparable in terms of quality of routine and IHC staining, we recommend using the MCB technique due to its short turnaround time.

Abstract
Background: Aspiration cytology is one of the first-line diagnostic tests in thyroid malignancies. Fine-needle aspiration cytology (FNAC) in thyroid lesions causes hemorrhagic smear and cell trauma, often leading to the repetition of smear and delay in diagnosis. This study was conducted to identify the diagnostically superior technique with regard to thyroid swelling and to assess the quality of smears obtained from FNAC and fine-needle nonaspiration cytology (FNNAC). Methodology: This was a prospective diagnostic study carried out for 2 years in a tertiary care center from South India. All patients with complaints of thyroid swellings, after examination, underwent FNNAC, followed by FNAC of the lesion. They underwent thyroidectomy when indicated. The final postoperative biopsy reports were compared with the preoperative reports of these two techniques (FNNAC and FNAC). The quality of smears was compared using Mair's score. Results: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in diagnosing malignancy were 93.4%, 100%, 100%, 98.78%, and 98.96% for FNNAC and 94.12%, 100%, 100%, 98.82%, and 99% for FNAC, respectively, which were comparable. Regarding the quality of smears, FNNAC had more smears with less blood in the background. FNAC had more smears with adequate cellularity. The difference in overall Mair's score between the two techniques was not significant (P = 0.28). Conclusion: No difference was found in the accuracy of FNAC and FNNAC in diagnosing thyroid lesions. Furthermore, the smear quality of both techniques was comparable. Hence, either can be used based on the operator's preference and experience.

Abstract
Metastasis to the parotid gland accounts for 10%-16% of parotid malignancies. Head and neck malignancies constitute the major bulk of metastatic lesions to the parotid. The other common primaries include the breast, kidney, lung, and prostate. Metastasis from the lung to the parotid is a relatively rare occurrence whose exact percentage is not known. Though intralymphatic spread into the parotid is known, intraparenchymal spread through hematogenous route is rare. The presence of intraparenchymal spread of lung Adenocarcinoma to the contralateral parotid diagnosed on fine needle aspiration (FNA) makes it a case worth reporting, highlighting the utility of cell block preparation and immunohistochemistry for a precise and early diagnosis.

Abstract
Medullary carcinoma of thyroid is a relatively uncommon malignancy, which can be sporadic and syndromic in nature. It commonly spreads to regional lymph nodes followed by spreading to distant sites. Breast is an uncommon site of metastasis of this malignancy. Our case is a 38-year-old woman married parous woman presenting to the outpatient department with complaints of lump in both the breasts. Fine-needle aspiration (FNA) was attempted, which revealed a malignancy more suggestive of a metastasis, which was confirmed on CT scan. A detailed history revealed that the patient is a known case of medullary carcinoma of thyroid. The report was given as metastatic medullary carcinoma to the breast after confirming with a calcitonin immunostain. Given the versatility of primary lesions in the breast, minimally invasive FNA cytology (FNAC) technique with adequate sampling helps in identifying metastatic lesions. Differentiating primary from metastatic lesions changes the course of management to the patient. Metastatic lesions should always be kept in mind in the occurrence of known malignancies, however rare the site of occurrence may be. Morphological clues and immunohistochemical work up aid in arriving at correct diagnosis.

Abstract
Sighting a case of subcutaneous panniculitis-like T cell lymphoma (SPTCL) in cytology is very rare in a clinical scenario. Among the differential diagnoses (D/D) of a subcutaneous nodule undergoing fine needle aspiration cytology (FNAC), it is hardly considered in the list. The common D/D on cytology would be panniculitis or a non-SPTCL lymphoma. To make a correct cytological diagnosis, the pathologist has to meticulously observe the type of inflammatory infiltrate, their morphology, the intimate admixture of the fat lobules, and background necrosis or macrophages. This article describes the cytological picture, D/D, and the prognostic factors associated with SPTCL in a young male. He was suspected of SPTCL after FNAC and later confirmed on histopathology with specific immunomarkers. We do not recommend the confirmation of SPTCL on cytology however, we would like to stress that it can be picked up and differentiated from its mimickers on FNAC.

Radiation induced sarcomas (RIS) on cytology is rare however need to be reported as they are histologically distinct from the primary tumor and arise years after completion of the radiotherapy. Fine needle aspiration cytology is mostly indicated in cancer patients suspected of recurrence/metastasis and rarely in secondary tumors post therapy or irradiation. Depending on the morphology and site of occurrence of RIS they can cause diagnostic difficulty with the primary carcinoma or sarcoma that was irradiated. Here we discuss a 49 yr old lady, known and treated case of carcinoma cervix who presented with multiple nodular swellings in the lower back and gluteal region and had clinical impression of metastatic carcinoma. The fine needle aspiration cytology smears revealed pleomorphic spindle shaped cells with abundant mitotic figures. Extensive immunocytochemical work up was done on the smear and cell block which helped to make a final conclusion of radiation induced pleomorphic sarcoma. The diagnosis of a tumor in a proven case of previous malignancy needs consideration of tumors secondary to therapy as well, along with the diagnostic differentials of metastasis or recurrence.

Abstract
Nocardiosis is primarily a pulmonary infection commonly seen in immunocompromised individuals. However, lymphocutaneous nocardiosis is observed in immunocompetent individuals often after trauma. The clinical and cytomorphological features of lymphocutaneous nocardiosis closely mimic the most common infections in India such as tuberculosis and mycetoma (very common cutaneous infection with discharging sinus). As it is crucial to differentiate nocardiosis from tuberculosis, to avoid unnecessary antitubercular treatment, special stains like modified Ziehl-Neelsen stain and Gram stain can be employed to differentiate the morphology of Nocardia from tuberculosis. Fine-needle cytology from these cutaneous lesions helps in yielding adequate material for rapid and accurate diagnosis of immediate specific antibiotic treatment. We report a rare case that presented with clinical diagnosis of tuberculosis but turned out to be nocardiosis on cytomorphology with simple and most feasible fine-needle aspiration method of tissue diagnosis and scrape cytology.

Abstract
Involvement of body fluids by adenocarcinoma is a common phenomenon. However, metastasis to the pericardial fluid by adenocarcinoma is a rare occurrence. The most common malignancies associated with malignant pericardial effusion are carcinoma of the lung, breast, esophagus, melanoma, lymphoma, and leukemia. Here, we discuss a case of a 36-year-old female with hemorrhagic pericardial effusion presenting with cardiac tamponade and psammoma bodies which was suspected and reported as metastatic papillary carcinoma of thyroid on cytomorphology; however, the immunocytochemical and radiological features confirmed metastatic papillary adenocarcinoma of lung contrary to the thyroid which is more common and expected.

Abstract
Phaeohyphomycosis is a chronic subcutaneous fungal infection caused by dematiaceous fungi, commonly involving the extremities, which present as single or multiple lesions mimicking a benign tumor. Fine-needle aspiration cytology (FNAC) is an easy method for the diagnosis of the lesion. Morphology of the fungus is characteristic with no difficulty for cytopathologist for identification; with a close differential diagnosis of Candida and Aspergillosis. The special stains like periodic acid schiff (PAS) highlights the fungus and the Masson Fontana confirm the melanin pigment and dematiaceous nature of the fungi. Liquid-based cytology (LBC) preparation of the aspirated material was attempted, which is not usually performed on day to day basis. However, in our case the conventional smears were better for appreciating the fungal morphology.

Abstract
Hepatoblastoma (HB) constitutes less than 1% of all pediatric malignancies and is the most common malignant tumor of liver in children. The fine-needle aspiration cytological (FNAC) diagnosis and sub-typing of this tumor is challenging, which is of critical importance from its treatment point of view. All cases with a clinicoradiological impression of "HB" during the study period of 1 year were subjected to ultrasound-guided (USG) FNAC and cell blocks were prepared in all cases. Detailed cytopathological examination was carried out based on the cytomorphological pattern and the cell blocks were used to correlate the findings and the final diagnoses were confirmed with the histopathological findings. Four cases were included during this study period. All were children, whose age ranged from 3 months to 10 years. All of them presented with mass per abdomen and increased serum alfa-feto protein (AFP) levels. On a detailed cytological examination, the clinical impression of HB was confirmed in all four cases with a subsequent histological correlation. Based on their distinct cytomorphological pattern, three of them were accurately sub-typed as"fetal type," wile the fourth was an "embryonal type of HB." All four cases had the evidence of extramedullary hematopoeisis. We conclude that a precise preoperative FNAC diagnosis with accurate sub-typing of HB is possible purely on cytomorphologic basis which has prognostic and therapeutic implications. Cell blocks are of great use for ancillary studies. Extramedullary hematopoiesis serves as an important "clue" in diagnosis.

Abstract
Granular cell tumor (GCT) is a rare benign neoplasm of Schwannian origin which accounts of 0.5% of soft tissue tumors. Although the most common site for GCT is tongue, it can occur at any site. GCT presenting as cutaneous nodule is rare, however cases have been reported in literature. We hereby document a case of 30 year female with a hyper-pigmented cutaneous nodule of anterior chest wall on the milk-line mimicking as an ectopic breast, diagnosed as GCT on fine needle aspiration cytology. We also add a note on the differential diagnoses of GCT with differentiating cytological features to emphasize on the correct diagnosis of GCT pre-operatively.
