Cytological study of body fluids has become integral part in both diagnostic and management of suspected malignant cases. The meticulous examination of body fluid for there cytomorphological properties throws light on the cause, presence of metastatic cells, typing of unknown cases, staging and prognosis of cancer.1) To study and evaluate current trends in cytological evaluation of body fluids for various pathologi­cal conditions in a tertiary care centre. 2) To analyse their frequency in relation to diagnosis.The present study is prospective type of analysis of 311 body fluids received in Department of pathology for duration of one year from Jan 2018 to Dec 2018 in our tertiary care centre. A total of 311 body fluid samples were analyzed in this study. Pleural fluid comprised of the major bulk of the study with 120 cases followed by peritoneal fluid with 100 cases. Non-malignant diagnosis was given in majority of the cases. Slight male preponderance was noted with male to female ration 1.37:1. Cytological analysis of body fluid is routine diagnostic investigation which offers definite aid to the treating physician. Preliminary body fluid analysis in resource limited setups still remains the most simple, convenient and cost effective technique in reaching to a particular diagnosis.

Introduction: Helicobacter Pylori and its association with carcinogenesis has significantly changed the field, establishing new guidelines for the detection of it. Carcinogenicity of H. Pylori necessitates grading the variables with visual analogue scale in accordance to Sydney system classification. The objectives of this study is to assess chronic gastritis and grade with visual analogue scale of Sydney classification. Methods: This is a prospective study of 3 years in which 50 gastric endoscopic mucosal biopsies were included in the study. Grading of the variables were done with reference to Sydney classification. Morphological changes in all cases were studied with special reference to atrophy, dysplasia, metaplasia, neutrophilic infiltration, lymphoid follicle formation, plasma cell infiltration & malignant changes along with identification of H. pylori. Results: Of the 50 cases studied for gastritis, 20 cases (44.4%) had Chronic H. pyloric gastritis followed by 18 cases (38.6%) of chronic gastritis with nonspecific features. Evaluation for graded variables showed 41 cases of gastritis with chronic inflammation of which 22 cases showed H. Pylori positivity. Of the 20 cases of gastritis showed inflammatory activity, 11 showed H. Pylori positivity. H. pylori was seen in 21 cases which could be graded. Of the 15 cases of gastritis showing surface epithelial damage, 9 cases showed H. pylori positivity. Chronic inflammation was most commonly observed and 22 of the 41 cases with chronic inflammation showed H.pylori positivity. Presence of H. pylori was an useful indicator in grading of gastritis. Conclusion: Visual analogue scale is an useful indicator to histologically grade chronic gastritis and detection of H. Pylori and helps in better evaluation of patient in preventing the further progression of the disease.

Introduction: Tumour Associated Tissue Eosinophilia (TATE) is an important phenomenon occurring in the tumour microenvironment and has a pivotal role. TATE is defined as “eosinophilic stromal infiltration of a tumour not associated with tumour necrosis or ulceration”. The exact role of TATE in malignancies is yet unclear but studies have shown that TATE usually has a favourable outcome in head and neck Squamous Cell Carcinoma (SCC). Therefore, more studies are needed to substantiate this data. Aim: To compare TATE between normal epithelium and Oral Squamous Cell Carcinoma (OSCC) and compare TATE between the histological grades of OSCC. Materials and Methods: A retrospective study was conducted at Dr. BR Ambedkar Medical College, Bangalore, Karnataka, India, from June 2019-January 2021 which included 50 cases, 10 from normal mucosa and 40 histopathologically diagnosed cases of OSCC. 1% congo red solution was used to stain 4 μm thick sections. The sections were examined at a high magnification (40X) and 10 microscopic fields were examined in succession for eosinophils. The average number of eosinophils observed were compared using univariate analysis, which included the Analysis of Variance (ANOVA) test and the Chi- square test and a p-value of 0.001 was considered statistically significant. Results: The mean value of tissue eosinophils increased in OSCC compared to normal mucosa, according to present study findings. When comparing different grades of carcinoma, statistical analysis revealed that well differentiated squamous cell carcinoma had a greater TATE than other grades, which was statistically significant (p-value <0.001). Conclusion: The higher eosinophil count in well differentiated OSCC compared to the other grades could be associated with a better clinical outcome for the patient. In OSCC, TATE can be utilised as a predictor of a good prognosis.

Introduction: Psoriasis is a chronic inflammatory immune mediated cutaneous disorder. Histologically it shows epidermal proliferation and neovascularisation in papillary dermis. Histological grading of psoriasis is done using Trozak Histological assessment Score (THS). Angiogenesis drives psoriasis. Vascular Endothelial Growth Factor (VEGF) and Cluster of Differentiation (CD34)/Micro Vessel Density (MVD) are proangiogenic cytokines in psoriasis and are overexpressed in psoriatic skin when compared to normal controls.Aim: 1) To analyse and compare the IHC expression of VEGF and CD34/MVD in skin biopsies of psoriasis cases and controls; 2) To compare the expression of VEGF, CD34/MVD with histological grade done by THS. Materials and Methods: A retrospective study was done in the Department of Pathology at Dr. BR Ambedkar Medical College and Hospital between September 2020 to August 2021. Twenty five cases and 25 controls (normal skin) were included in this study. Histopathology/Immunohistochemistry (IHC) for VEGF and CD34 was performed. Suprabasilar layers of the epidermis were assessed for VEGF expression. Cell showing granular positivity within the PARTICULARS OF CONTRIBUTORS:
