Abstract
Aneuploidy is frequently noted in malignant tumours. There is much controversy about its cause and effect in relation to malignant tumours. Failure of the spindle checkpoint caused by mutation of the responsible genes may be one of the important factors for the development of aneuploidy. Telomere dysfunction may also be a possible source of failure of cytokinesis resulting in aneuploidy. Evidence such as tumour specific aneuploidy, presence of aneuploidy in various preneoplastic conditions, increased frequency of genetic instability in aneuploid cell lines compared with diploid cells, and mutation of mitotic checkpoint genes suggests that aneuploidy possibly plays an active role in carcinogenesis. In this brief review, the various aspects of aneuploidy with special emphasis on its mechanism of development and impact on progression of cancer are discussed.

Abstract
In this study, we evaluated the usefulness of fine needle aspiration cytology (FNAC) in the diagnosis of soft tissue tumours. We have also assessed the various pitfalls of FNAC of soft tissue tumours. This was a retrospective study and here we analysed only 82 histopathology proven cases of FNAC of soft tissue tumours diagnosed in a five and half year period. On histopathological examination, 55 of these cases were malignant and 27 were benign. There was a total of 15 recurrences and histopathology was available prior to FNAC in only eight of these cases. Therefore, excluding these eight cases, malignant tumours were primarily diagnosed by FNAC in 47 cases. The sensitivity, specificity and positive predictive value of FNAC in diagnosis of soft tissue tumours were 91.5%, 92.5% and 95.5%, respectively. Only 22 of 47 cases (46.8%) were correctly categorized. There were two false-positive and four false-negative cases. One case each of fibromatosis and schwannoma were reported as sarcoma. False-negative cases were fibrosarcoma (1), malignant nerve sheath tumour (2) and haemangiopericytoma (1). FNAC was very useful in distinguishing benign from malignant soft tissue tumours. However, it was not so effective in exact categorization of tumours.

Abstract
In this retrospective study, we tried to ascertain the fine needle aspiration cytology (FNAC) features of six histopathologically proven cases of the follicular variant of papillary carcinoma of thyroid (FVPCT). These proven cases were diagnosed from 1998-2000. May-Grunwald-Giemsa and haematoxylin & eosin stained FNAC smears were studied independently by two observers (MP and PD) for detailed cytological features. A comparison of the cytological features was undertaken with those reported in the literature. There were six cases of which only one case was diagnosed as FVPCT while the other five cases were diagnosed as follicular neoplasm (four cases) and neoplasm unclassifiable (one case) on FNAC smears. All these cases showed abundant cellularity with a prominent follicular pattern. No papillae were identified in any of the cases. Syncytial clusters (five cases), nuclear grooves (six cases), nuclear inclusions (one case) and chewing gum colloid (three cases) were noted in variable proportions. We suggest that a differential diagnosis of FVPCT should be considered if the cytology smears show abundant cellularity, syncytial clusters and follicular arrangement along with thick colloid.

Abstract
The ovary is a frequent site of metastasis. However the incidence of metastatic tumours to the ovary is not exactly known. The reported incidence in the literature varies from 2.95 to 27.8%. The gastrointestinal tract (GIT) and the breast have been reported to be the frequent primary sites of the metastatic deposits in the ovary. The aim of this study was to determine the incidence of metastatic ovarian tumours and analyse their detailed morphologic features. All the metastatic ovarian neoplasms diagnosed in the Department of Cytology and Gynaecologic Pathology, Post Graduate Institute of Medical Education and Research, Chandigarh from 1996 to 2000 were included in the study. Nineteen metastatic tumours out of a total of 363 ovarian neoplasms (5%) were identified. The patients frequently presented with abdominal distension and mass. The age ranged from 17 to 75 years. The primary site was unknown in ten cases. Uterus was the most common site (4 cases) followed by GIT (3 cases). Six Krukenberg's tumours were identified. In cases simulating the primary ovarian tumours, the following features were helpful to suggest the metastatic deposit in the ovary: bilaterality, no significant ovarian enlargement, vascular emboli, a Krukenberg's morphology, no omental deposits and the absence of transition from benign to malignant epithelium.

Abstract
The cytologic features in twelve cases of giant-cell tumor (GCT) and five cases of giant-cell tumor of tendon sheath (GCTTS) diagnosed by fine-needle aspiration cytology (FNAC) are described. All of these cases were histopathologically confirmed. The aspirates of GCT are composed of a dual population of mononucleated spindle cell and multinucleated giant cells. The peripheral adherence of giant cells to the spindle cell is the feature of diagnostic significance in GCT. In GCTTS, the aspirate consists of a polymorphic population composed of mononuclear histiocyte-like cells, hemosiderin laden macrophages, foamy macrophages, and a few multinucleated giant cells. FNAC can be used as a diagnostic tool for an early and accurate detection of these two giant cell-rich lesions, since the cytologic features when evaluated in conjunction with the clinical and radiologic features are sufficiently diagnostic.

Abstract
OBJECTIVE To determine whether loop diathermy excision of the transformation zone and laser vaporisation are equally effective in the treatment of cervical intraepithelial neoplasia. DESIGN Randomised controlled trial. POPULATION Women referred for evaluation of cytological abnormality who were considered suitable for outpatient local destructive treatment. SETTING Seven colposcopy units in the North West Region. METHODS Loop diathermy excision of the transformation zone and laser vaporisation. MAIN OUTCOME MEASURE Smear reported as moderate dyskariosis or worse following treatment. RESULTS Of 289 women randomised, 285 had one or more smears following treatment. Women were more likely to have a smear reported as moderate dyskariosis or worse following laser vaporisation [hazard ratio 3.01 (95% CI 1.27 to 7.12)]. The cumulative risk of a smear reported as moderate dyskariosis or worse was 6.0% at six months and 12.1% at three years in those allocated laser vaporisation, and 2.0% at six months, and 3.3% at three years in those allocated loop diathermy excision of the transformation zone. CONCLUSIONS Loop diathermy excision is a more effective treatment of cervical intraepithelial neoplasia than laser vaporisation.

Abstract
PURPOSE To evaluate the role of image-guided fine-needle aspiration cytology (FNAC) of deep-seated lymph nodes. MATERIAL AND METHODS Image-guided FNACs were performed on 242 patients of deep-seated lymph nodes which included thoracic, retroperitoneal and abdominal nodes. A sterile 3.5/5-MHz micro convex sector probe was used for localisation of the node. The FNAC was performed using a 0.7- to 0.9-mm needle with the stylet removed and attached to a 20-ml syringe and FNAC handle after the needle was visualised in the lesion. For each case a minimum of 4-5 smears were made, and two observers without bias interpreted the smears. RESULTS A total of 242 patients were aspirated, of which 216 (90%) aspirations were US-guided and the remaining 26 (10%) were CT-guided. Adequate material for cytologic diagnosis was obtained in 208 (86%) patients with a similar diagnostic accuracy. The aspirate material was non-representative or scanty in 34 (14%) patients. The most common cytological diagnosis was tuberculosis/consistent with tuberculosis seen in 108 (45%) patients followed by metastasis (17%) and reactive hyperplasia (10%). Non-Hodgkin lymphoma was diagnosed in 22 (9%) patients. All patients were briefly followed for a period of 1 1/2 to 2 years (mean 1 year). CONCLUSION Image-guided FNAC has a pivotal role, and is a cost-effective tool for establishing tissue diagnosis as a primary investigative modality. It is also helpful and accurate in follow-up of patients with a known malignant disease, thereby avoiding surgical intervention.

Abstract
BACKGROUND Radiotherapy, open surgery and endolaryngeal excision (with or without laser) are all accepted modalities of treatment for early stage glottic cancer. Case series suggest that they confer similar survival advantage. Opinions on optimal therapy vary across disciplines and between countries. OBJECTIVES To compare the effectiveness of open surgery, endolaryngeal excision (with or without laser) and radiotherapy in the management of early glottic laryngeal cancer SEARCH STRATEGY Electronic search of MEDLINE (from 1966 to October 2000), EMBASE (from 1980 to October 2000), CINAHL (from 1982 to October 2000) and CancerLit (from 1963 to October 2000) databases and the Cochrane Controlled Trials Register. SELECTION CRITERIA Randomised controlled trials (RCT) comparing open surgery, endolaryngeal resection and/or radiotherapy DATA COLLECTION AND ANALYSIS Two reviewers independently assessed RCTs identified from the electronic searches for eligibility and methodological quality. All authors of the review discussed the results of these assessments. MAIN RESULTS Only one RCT was identified which compared open surgery and radiotherapy among a substantial number of patients with early glottic laryngeal cancer. REVIEWER'S CONCLUSIONS There is currently insufficient evidence to guide management decisions on the most effective treatment. Interpretation of the only large scale RCT comparing open surgery and radiotherapy in patients with early glottic cancer is limited because of concerns about the adequacy of treatment regimens and deficiencies in the reporting of the study design and analysis. Endolaryngeal resection of early glottic tumours is becoming more common and a well designed multicentre RCT is warranted.

Abstract
Literal meaning of artefact given by 'Oxford Advanced Learner Dictionary' is 'a thing made by people'. In medical science 'the fact' is not true; but we observe routinely is called artefact. We face various types of artefacts in daily reporting of pathology specimen. Many times artefacts hinder the actual diagnosis. The artefacts i. e. fixation artefact, processing artefact, staining artefact, mounting artefact, air bubbles etc. can cause difficulty in diagnosis and a pathologist should be trained to identify those artefacts.

Abstract
OBJECTIVE To quantitate different antigens by flow cytometric immunophenotyping (FCI) in small round cell tumors (SRCTs) and to compare the FCI technique with immunocytochemistry (IC). STUDY DESIGN IC and FCI were performed on 24 consecutive cases of SRCT on fine needle aspiration biopsy material using a panel of antibodies--e.g., cytokeratin (CK), leukocyte common antigen (LCA), desmin, epithelial membrane antigen, neuron-specific enolase, chromogranin, retinoblastoma gene product, neuroblastoma clone (NB84a (NB), vimentin and Mic-2 gene product. IC was done by indirect immunoperoxidase and FCI by indirect immunofluorescence onflow cytometry. RESULTS In Ewing's sarcoma, with the help of FCI, positive results were obtained in an additional 4 samples in CK, 2 samples in actin and 3 samples in desmin. Similarly, one each sample was additional positive regarding Mic-2 and vimentin by IC. In cases of neuroblastoma with the help of FCI, additional positive results were obtained in one each sample of CK, LCA and NB and two in actin. Combined use of FCI and IC helped to show chromogranin positivity in an additional two cases. Divergent differentiation was noted in four cases of Ewing's sarcoma, one neuroblastoma and two peripheral neuroectodermal tumors. CONCLUSION FCI technique is sensitive, more objective and quantitative in comparison with manual absorbance-based microscopic detection of enzyme immunohistochemistry products. FCI may determine divergent differentiation in SRCTs.

Abstract
OBJECTIVE To analyze nuclear image morphometry in fine needle aspiration cytology smears of different groups of malignant round cell tumors (MRCTs) to evaluate its diagnostic role. STUDY DESIGN In this study there were 55 cases of MRCT, consisting of 18 Ewing's sarcoma (EW), 10 neuroblastoma (NB), 5 non-Hodgkin's lymphoma (NHL), 6 rhabdomyosarcoma (RMS), 4 peripheral neuroectodermal tumor (PNET), 8 Wilm's tumor (WT), 2 retinoblastoma (RB) and 2 undifferentiated round cell tumor (URCT). A Leica image cytometer with Quantimet 600 software (Leica, Cambridge, U.K) was used to measure nuclear area, nuclear diameter, nuclear perimeter, nuclear convex perimeter (CP), nuclear roundness and nuclear convex area on hematoxylin and eosin-stained cytologic smears. At least 100 cells were studied in each case. RESULTS The RB group of tumors showed the highest mean nuclear area (NA), convex area (CA), CP, diameter (D), perimeter (P) and roundness (R). RMS had the highest mean CA, and URCT had the highest mean roundness. ANOVA was performed on the tumors and showed significant differences for all the variables in all the groups (P < .000). All the morphometric data (except roundness) were significantly different in RMS versus all other MRCTs except RB. Similarly, morphometric data on WT were also significantly different from that on NHL. Most of the morphometric data (except CA and R) showed significant differences between RB and all other MRCTs except RMS. PNET, EW and NB could not be differentiated with those variables. CONCLUSION RMS and RB could successfully be differentiated from all other MRCTs with the help of morphometry. It was not possible to differentiate RMS and RB by image cytometry (ICM) since the ICM data overlapped in those two groups. It was possible to differentiate WT and NHL with ICM. Nuclear ICM was not significantly different in the NB, PNET and ES groups, and probably ICM would not be very helpful to differentiate these groups of MRCT.

Abstract
OBJECTIVE To evaluate the role of fine needle aspiration biopsy (FNAB) material in 25 HIV-positive cases with lymphadenopathy. STUDY DESIGN We selected 25 cases for the present study who were enzyme-linked immunosorbent assay positive for HIV (HIV-1). FNAB was performed as a routine, outdoor procedure with informed consent of the patient. For each case, along with routine May-Grünwald-Giemsa and hematoxylin and eosin staining, Ziehl-Neelsen staining for acid-fast bacilli and periodic acid-Schiff staining for fungi were performed wherever necessary. RESULTS A total of 28 sites were aspirated from 25 HIV patients. All these patients were heterosexual, and none had a history of drug abuse. FNAB was performed under ultrasound guidance in all four cases of a retroperitoneal group of lymph nodes. The most common FNAB diagnosis was reactive lymphoid hyperplasia (10), followed by tuberculosis (8). There were three cases diagnosed as fungal infection (two, Cryptococcus; one, histoplasmosis). FNAB of a case of lymph node was suggestive of tuberculosis. There was one case each diagnosed as non-Hodgkin's lymphoma and squamous cell carcinoma (metastatic). One case of a small axillary lymph node did not yield representative material. CONCLUSION FNAB is a relatively inexpensive initial investigative technique in the diagnosis and management of HIV-positive patients. It can obviate the need for surgical excision and enable immediate treatment of specific infections.

Abstract
OBJECTIVE To analyze cases of palpable cutaneous/ subcutaneous scalp nodules and evaluate the clinical features and role of fine needle aspiration cytology (FNAC) in their diagnosis. STUDY DESIGN A total of 1,022 cases of metastatic malignancies at various sites were analyzed over a period of two years. FNAC was performed as a routine outpatient procedure for palpable lesions and under ultrasound or computed tomographic guidance for nonpalpable, internal sites. Histologic correlation was done when possible. RESULTS Eighteen cases were found to be metastatic scalp nodules. The scalp as a metastatic site constituted 1.76% of all metastatic sites, 7.72% of extranodal sites, and 15.3% of extranodal and extrahepatic sites. Of the 18 cases, 7 (38.9%) had primaries in the head and neck region (thyroid, 3; orbit, 1; tonsil, 1; tongue, 1; and parathyroid, 1). Cutaneous/subcutaneous metastasis was encountered in 58 patients, and the 18 cases of scalp metastasis constituted 31.03% of all cutaneous sites. CONCLUSION Careful examination of the skin on the entire body, with particular attention to the scalp, should be done when a primary internal malignancy or recurrence is suspected. FNAC is a very helpful and cost-effective modality in determining the nature of such lesions.

Abstract
This study was carried out with the objective of studying the cytomorphology of the wide variety of chest-wall lesions. Two hundred twenty-seven chest-wall lesions were studied over a period of 4 yr. Routine May-Grünwald-Giemsa (MGG) and hematoxylin-eosin (H&E) slides were studied along with special stains, whenever required. The malignant lesions comprised 36.13% of all cases (81/227). Of the 126 benign lesions, the majority were inflammatory in nature (68/126), the next commonest lesion being lipoma (38/126). Rare cases of tuberculosis involving the sternum, epithelioid leiomyosarcoma, and neuroendocrine tumors involving ribs, malignant nerve sheath tumors involving the chest wall, metastatic carcinoma of the stomach and prostate, and papillary carcinoma thyroid are reported in this series. Histopathology was available in 24 cases, and hematological correlation in one case. A 100% cytohistological and cytohematological correlation was found, with no false positives or false negatives. In conclusion, fine-needle aspiration cytology is a rapid, diagnostic tool, eliciting many interesting lesions in the chest wall. It is useful not only in detecting primary and metastatic lesions, but also in follow-up of tumor recurrence.
