BACKGROUND: Urine cytology is useful to diagnose urinary neoplasms, whereas its role in the study of microhematuria is debatable. Usually, standard urinalysis (dipstick test and sediment examination with bright field microscope) detects the presence of microhematuria, but only urinalysis with phase-contrast microscopy (PCM) (dipstick test and sediment examination with PCM) allows the observation of red blood cell (RBC) morphology and identify their source. Usually glomerular diseases show RBCs with morphological alterations in high percentages, whereas on urologic bleeding, RBCs are rather homogeneous without morphological alterations...

BACKGROUND: Liquid-based cytology (LBC) can improve adequacy, monolayer quality with a clean background compared to conventional smears (CS). AIMS AND OBJECTIVES: The objective was to compare the quality and diagnostic yield of CS and LBC in routine cytological investigations. MATERIALS AND METHODS: This retrospective study consisted of 306 samples (255 gynecological, 39 nongynecological, and 12 fine needle aspiration cytology [FNAC]) during a 2-year period (2019-2020)...

BACKGROUND: Immunotherapy currently stands as a novel treatment option, specifically in cases of advanced non-small cell lung carcinoma (NSCLC). Expression of programmed death ligand-1 (PD-L1) in tumor cells forms the mainstay for the use of anti-PD-L1 monoclonal antibodies in the treatment of NSCLC. AIMS: The objectives of the study were to assess utility of cell blocks for testing of PD-L1 in adenocarcinoma lung and to compare the expression of PD-L1 in cell blocks and the corresponding biopsy specimens...

AIMS: Thyroid nodules are one of the most frequent medical issues in endocrinology in our country and around the world. The appropriate evaluation of the nodule is critical in the management of patients. Fine needle aspiration cytology (FNAC) is one of the most accurate tools for evaluating these nodules. Conventional and liquid-based (LB) methods are available for thyroid FNAC. In this paper, we aim to determine the best cytological method for the evaluation of thyroid fine needle aspiration materials...

BACKGROUND: HPV 18 is one of the important oncogenic types. HPV 18 is generally evaluated together with HPV 16 and/or high-risk HPV types in light microscopic studies. The purpose of this study was to evaluate the impact of only HPV 18 on the nucleus/cytoplasm ratio, and chromosomal and nuclear degenerative changes in liquid-based samples. MATERIALS AND METHODS: Eighty liquid-based cervical samples were used in this retrospective study. These smears were prepared by HPV Deoxyribonucleic Acid (DNA) detection and genotyping with the Cobas 4800 HPV system...

BACKGROUND: Lymphoblastic lymphoma (LBL) accounts for about 2% of all lymphomas. Recognition of T/B-LBL albeit of their rareness is very important as they present as localized diseases with low tumor burden. They can present both at nodal and extranodal sites. Limitation of diagnosis and classification of lymphoma on fine needle aspirate (FNA) can be minimized by clubbing it with flowcytometric immunophenotyping (FCI) to ensure diagnostic accuracy rapidly. AIM: Study of a series of 18 cases of LBL to assess the utility of FCI on FNA and effusion samples in extramedullary LBL...

CONTEXT: The conventional smears (CS) and Liquid based cytology (LBC) are important tools to detect carcinoma cervix and its precursor lesions. AIMS: The present study was done to compare the cytomorphological features of cervical lesions using both techniques and compare with the histopathological diagnosis. SETTINGS AND DESIGN: This was a prospective observational study over a period of 1.5 years at a tertiary care hospital. METHODS AND MATERIAL: A total of 969 women in the age group of 21-65 years presenting with either routine screening or complaints of vaginal bleeding, discharge, or pelvic pain were enrolled for the study...

BACKGROUND: Serous effusion cytology (SEC) reporting is important for the management of the cancer patient. The International System for Reporting Serous Fluid Cytology (ISRSFC) provides tiered reporting terminology to standardize practice, looking into the risk of malignancy (MAL) for each category. In this study, we have assessed the utility of the ISRSFC and reported our experience at a tertiary cancer center. MATERIALS AND METHODS: Serous fluid cytology reported from January 2019 to December 2020 was categorized according to ISRSFC diagnostic categories: nondiagnostic (ND), negative for MAL (NFM), atypia of undetermined significance (AUS), suspicious for MAL (SFM), and MAL...

Castleman disease is a nonmalignant, lymphoproliferative disorder. Unicentric disease type involves a single enlarged lymph node or nodal regions, and multicentric disease involves multiple lymph node site involvement. We present a case of 26-year-old young female presented to outpatient with complaint of generalized weakness and abdominal pain for last 2 months. Her imaging included positron emission computed tomography which showed soft-tissue mass along the body of pancreas. Endoscopic ultrasound done showed nodal mass with extensive calcification and doppler endoscopic ultrasound showing arborising vessels...

INTRODUCTION: Cellblock (CB) with immunohistochemistry (IHC) is practically indispensable in the diagnostic workup of serous effusions; however, CB requires a minimum of 15-20 h for routine histopathological processing. A reduction in processing time can expedite a faster diagnosis. AIM: This study was undertaken to evaluate the utility of the heat-induced CB (HICB) technique. MATERIAL AND METHODS: Two sets of agar-embedded CBs were processed from 50 effusion samples...

INTRODUCTION: Fine Needle Aspiration Cytology (FNAC) is a well-established early diagnostic technique for evaluating mass lesions in adult patients. Now, FNAC in children is gaining acceptance and is used as a first-line investigation in diagnosis of pediatric lesions. AIMS: To analyze the cytomorphologic spectrum of head and neck lesions in pediatric age group with histopathological correlation wherever possible and to study the utility of FNAC in pediatric head and neck lesions...

OBJECTIVE: To explore the feasibility of sampling Chinese patients by suction curettage for cytological and histological screening of endometrial cancer related to Lynch syndrome. METHODS: This retrospective study enrolled patients who underwent endometrial biopsy at our hospital between May 2018 and January 2019. Endometrial sampling (cytological and micro-histological specimens) was conducted by suction curettage. The gold standard for diagnosis was traditional sharp dilation and curettage (D&C)...

BACKGROUND: Oral cancer is a major health problem in developing countries. Cytology has been widely accepted as a tool in the early diagnosis of cancer. OBJECTIVES: To evaluate the diagnostic utility of four different cytology techniques, that is, modified brush cytology (BR) technique, brush cytology cytocentrifugation (BRCC) technique, modified scrape cytology (SR) technique, and scrape cytology cytocentrifugation (SRCC) technique and correlate the cytopathological diagnosis with the available histopathological diagnosis...

To estimate the feasibility of diagnosing ovarian cancer, fallopian tube cancer, and primary peritoneal cancer through endometrial cytology, we performed a systematic review and meta-analysis to calculate the pooled positive rate of malignant cells in endometrial cytology samples. We queried PubMed, EMBASE, Medline, and Cochrane Central Register of Controlled Trails from inception to November 12, 2020 for studies estimating positive rates of malignant cells in endometrial cytology samples from patients with ovarian cancer, fallopian tube cancer, and primary peritoneal cancer...

BACKGROUND AND AIMS: After liquid-based cytology (LBC) technique developed for cervical cytology, it has been used for nongynecological samples and has been very successful. It offers having extra slides of the samples for further examination and ancillary tests. Moreover, cell blocks can be formed from the residue material. The study aimed to evaluate the importance of preparing a second LBC slide or a cell block from the residue material of thyroid fine needle aspiration (FNA) samples to reach a definitive diagnosis in cases diagnosed as nondiagnostic (ND) after the first slide...
