..To delineate the cytomorphologic appearances of hepatoblastoma (HBL) in the largest series to date and to evaluate the feasibility of subtyping on fine needle aspiration cytology (FNAC)...

....

..Anaplastic CCSK is liable to misdiagnosis as Wilms tumor (WT) with unfavourable histology. Presence of eccentric cytoplasm in cord cells and nuclear grooves are the key to differentiation from Wilms tumor, including anaplastic variants...

....

..The most prevalent genotype observed was type 2 in contrast to many studies from other parts of the world where genotype 1 was the most prevalent type, suggesting geographical variation...

..Outcome for patients with Wilms tumor (WT) with favorable histology is good. Deletions of chromosomes 1p and 16q impart a poorer outcome. Value of apoptotic protein expression is not clear...

..Adjunctive testing using two tests in a parallel or sequential combination can improve diagnostic accuracy, decrease costs and minimise referral rates...

..Presentation of granulocytic sarcoma (GS) as an effusion is very rare and most cases are misdiagnosed as lymphoma infiltration. Detailed descriptions of cytological features of GS in an effusion have not been published to date...

..A meticulous search may reveal the presence of delicate, thin, faintly stained, branching filaments of Nocardia on routine Papanicolaou stain. Special stains and culture studies are useful in confirming the diagnosis...

..To evaluate Bcl-xL, Bax, PCNA, cytokeratin 19 (CK-19), glycogen content and DNA ploidy expression in hepatoblastoma (HB) and their prognostic value...

..jirovecii isolates obtained from HIV-infected patients with a clinical diagnosis of Pneumocystis carinii pneumonia (PCP) admitted to our tertiary care reference health center in New Delhi, India...

..Oncocytic carcinoid tumor of the lung is a rare variant of pulmonary carcinoid. This report describes the morphologic appearance of this rare tumor on filter membrane preparation along with potential pitfalls...

..To review nephrectomy specimens for pediatric renal tumors seen over a period of 9 years (1995-2003)...

..To study the role of cytology and polymerase chain reaction (PCR) for the detection of Pneumocystis carinii pneumonia (PCP) in bronchoalveolar lavage fluid (BALF)...

..We evaluated the efficacy of a limited two-antibody panel comprising calretinin and Ber-EP4 on cytospin and cell block preparations, in 100 effusion samples...

....

..Examination of aqueous humor aspirate revealed presence of malignant cells. Atypical hypopyon, even unilateral can be an indication of relapsing ALL in a child...

..However, it is very rare to detect these organisms in voided centrifuged urine cytology. We, report this rare finding in a 25-year-old patient who presented with achylous hematuria...

..A wide spectrum of HPV types is seen in north Indian women, with the majority being HPV-16 in all grades of histology. A vaccine against HPV-16 and HPV-18 could prevent two thirds of cases of high-grade cervical neoplasia...

..Toluidine blue staining is not only a reliable method for rapid staining and diagnosis, it also permits preservation of cytological material by destaining and restaining with permanent stains...

..Pneumocystis pneumonia appears to be a common opportunistic infection in renal transplant receipients in India...

..Application of scoring in a step-wise manner, on atypical aspirates, can help in selection of cases suitable for biopsy...

..A close inspection of the cytologic features and comparison with the histopathology of the primary tumor helps in making an accurate diagnosis...

..Prompt recognition of these infections permits the clinician to institute appropriate therapeutic modification and improved survival...

..It substantiates embryological chronology of events during the cephalad migration of the primordial germ cells through the developing diaphragm, prior to its closure...

..We present the case of a 25-year-old patient with extramedullary involvement of lymph node and cerebrospinal fluid by AML M7, describing in detail, the morphological features on aspiration as well as exfoliative cytology...

..This study was undertaken to compare the diagnostic accuracy of HPV testing by hybrid capture II (HC-II) with conventional cervical smear cytology for squamous intraepithelial lesions (SIL)...

..In tissue sections, both features were seen in all cases, but with a patchy distribution. The cytological features of GCTTS are uniform, and FNA cytodiagnosis is possible...

..In the present study, cytological findings in 32 clinically unsuspected cases of filariasis were reviewed with emphasis on morphological details and image morphometric measurements...

..Since this tumor is usually unresectable but has a favorable prognosis as compared to hepatocellular carcinoma, a correct diagnosis is essential for appropriate management and prognostication...

..Detailed descriptions about the cytomorphological features of ALCL are few and do not illustrate the various categories of cells, which we have done in this study...

..We report the case to emphasize the importance and possibility of diagnosing of ChRCC on cytology. In addition, the extensive calcification as seen in our case is an unusual cytological finding not previously reported in cytology smears...
