ABSTRACT
Background: Malignant epithelial tumours are the most common ovarian cancers and also the most lethal gynaecological malignancies. This study was undertaken to analyse histomorphological spectrum and clinicopathological correlation of ovarian tumours. Methods: This retrospective study was done for the period of one year at Department of Pathology, New Civil Hospital, Surat, which is a tertiary health care center. Here we studied 55 cases of ovarian mass received in formalin, which were subjected to histopathological examination and immunohistochemistry as and when required. Results: In total, 55 ovarian tumour specimens were examined. Out of which 28 cases (51%) were benign, 3 cases (5%) were borderline and 24 cases (44%) were malignant. Most common histological type was surface epithelial tumours (60%) followed by germ cell tumours (13%). The commonest benign tumour was mucinous cystadenoma and commonest malignant tumour was serous adenocarcinoma. Malignancy was quite common in ovarian masses in our institute. Conclusions: Ovarian tumours are quite common in our set up and epithelial tumours are the commonest variety of ovarian tumours. The histological type of ovarian tumour correlates with the prognosis of the tumour.
ABSTRACT
Leiomyosarcoma, a rare malignancy of smooth muscle may arise from the retroperitoneum. They often reach a large size before diagnosis is made. Patient presents with vague symptoms, as such retroperitoneal malignancies are related to displacement of organs and obstructive phenomenon. The present paper is one of the very few case reports of retroperitoneal leiomyosarcoma which illustrates the presenting symptoms, gross and microscopic findings, treatment modalities and prognostic indicators of a 70 years old male seen at Government medical college, New Civil Hospital, Surat.
ABSTRACT
Background: Cancers of the upper aero-digestive tract (UADT) constitute 3.5-4% of all malignancies. Majority of cases are squamous cell carcinomas which are related with various epidemiologic factors. Aims & Objective: The objective of this study is to know the histopathological spectrum of tumours of UADT. Material and Methods: This study comprises of 156 cases of histopathological diagnosed tumours of upper aero digestive tract who attended new civil hospital, government medical college, Surat, from August 2010 to august 2012. All prospective and neoplastic cases were included and retrospective and non- neoplastic cases were excluded. Routine paraffin sectioning and staining was done and immunohistochemistry was applied when required. Results: Out of total 156 cases of UADT, 129 malignant, 19 cases benign and 8 were carcinoma in-situ cases. In malignant cases, 124 (96.00%) cases of carcinomas, 1 (0.80%) case of sarcoma, 2 (1.60%) cases of melanoma, and 2 (1.60%) cases were of lymphomas. Most common site of carcinoma was oral cavity (tongue). Most common carcinoma was Squamous cell carcinoma. Most common site of SCC was hypo pharynx (pyriform Fossa), followed by oral cavity (tongue) and larynx (supra glottis). In benign tumours, most common site was nasal cavity (7 cases) and common varieties were Angiofibroma and Capillary Haemangioma. Conclusion: Tumours of UADT are predominant in males affecting older age group. People with tobacco chewing, smoking, alcoholism, poor socioeconomic background, mixed diet and poor oral hygiene are more vulnerable.
ABSTRACT
Background: Most of the patients suffering from malaria shows reduced Red cell count, leukopenia and varying degree of thrombocytopenia but it is rarely associated with haemorrhagic manifestations. Aims & Objective: This study was undertaken to correlate the incidence and severity of thrombocytopenia with the prevalent species of malaria. Material and Methods: Total 1480 Patients were included in this study after positive identification on PSMP. Platelet count was done by haematology analyser (Sysmax Kx 21). Results: Incidence of thrombocytopenia was seen in 83.80% and 74% cases of P. falciparum and P. vivax malaria respectively. Severe thrombocytopenia in P. falciparum was found in 7.70% cases while in P. vivax 3.67% cases. No difference was observed in incidence of thrombocytopenia in both age groups in relation to both prevalent species. In paediatric age group, significant leukopenia was found in 22.22% Cases of P. falciparum in comparison to P. vivax (14.96%). Hb less than 10 mg/dl was found in 66.11% cases in P. Falciparum while in P. vivax it was found in 40.13% cases. In adults leukopenia was found in 27.46% Cases of P. falciparum in comparison to P. vivax 22.61% cases. Hb less than 10 mg/dl was found in 41.28% cases in P. falciparum while in P. vivax it was found in 28.57% cases. Conclusion: Severe thrombocytopenia is commonly associated with P. falciparum malaria however severe thrombocytopenia also observed in P. Vivax malaria. In both species of malaria significant number paediatric patients present with low Hb level compared to adults. In P. vivax malaria significant number of adult patients presented with leukopenia as compared to paediatric patients.
ABSTRACT
Background: The impact of diagnostic immunohistochemistry for the surgical pathology is legendary especially when it provides true identity of undifferentiated tumours. This not only is important for prognostication & therapy but also provide further insights into the pathobiology of these tumours. Aims & Objective: This study was undertaken to determine the role and significance of immunohistochemistry for accurate diagnosis and subtyping of undifferentiated malignant tumours as it is essential in guiding therapy and prognosis. Material and Methods: Immunohistochemical staining (IHC) performed was based on Peroxidase Antiperoxidase (PAP) method on paraffin sections, using appropriate mono/polyclonal antibodies. Total 74 cases including six consultation cases were studied from August 2008 to November 2011, which were reported as undifferentiated or poorly differentiated malignant tumor using routine hematoxylin- eosin stains. Results: The histopathology and IHC reports of 74 tumours were reviewed and assigned to appropriate categories. It was possible to arrive at a diagnosis in 73 cases (98.65%) with the help of IHC. Carcinoma was the commonest diagnosis (27 cases, 36.50%) followed by lymphoma (18 cases, 24.32%), sarcoma (14 cases, 18.92%), malignant melanoma (3 cases, 4.05%) and neuroblastoma (3 cases, 4.05%). Conclusion: Immunohistochemistry is helpful in the majority of difficulties arising during histological diagnosis of undifferentiated malignant tumours and serves as a diagnostic, prognostic, and predictive tool.
ABSTRACT
Background: Malaria is a major health problem and infects many individuals despite of various efforts to control it. The present study was aimed to observe characteristics of malaria, seasonal variation and prevalence of malaria in our region. Methods: This retrospective study was conducted in our institute from period of January 2012 to December 2012. All the fever cases undergone investigations for malarial parasites were included in present study for defined time period. All the laboratory data of the patients having fever were retrieved from the Pathology Laboratory of our institute. Results: out of total 32674 reports studied 4907(15.01%) were positive for malaria with overall Slide positivity rate and slide falciparum rate were 15.01% and 38.29% respectively. Incidence of malaria occurs throughout year with increased incidence of P. falciparum in monsoon. Conclusion: In the present study incidence of malaria was higher in monsoon in comparison to other seasons. But throughout the year no declining trends in incidence of malaria was observed. P. vivax malaria was more commonly observed in our study but incidence of P. falciparum increased in monsoon.
ABSTRACT
Mortality in sickle cell disease is high at young age group. So it is necessary to find out the cause of death in young patients with sickle cell disease. We are presenting 5 cases of sudden death in young adults with undiagnosed sickle cell disease. The provocative factors for those terminal events were vasoocclusive crisis. In our patients crisis was secondary to fever (infection), conductive arrhythmia, cardiovascular collapse, post partum shock and hemorrhage. On microscopic examination of viscera, not a single patient showed signs of chronic organ damage, sequestration crisis or acute chest syndrome, which are the common causes of death in sickle cell disease.
