Background: Sickle cell disease (SCD) has a high mortality rate with unexpected sudden death. So, the purpose of the study was to analyze clinical and/or autopsy findings at the time of death among sickle cell disease (SCD) patients. Methods: This is a retrospective study of SCD patients who died between January 2011 to December 2011 and the morphological evidence of the cause of death was studied in a tertiary care hospital of south Gujarat. The clinical data, including the age, gender, symptoms and the major autopsy findings and cause of death were obtained for each patient that included histopathological examination. Results: A total of 472 autopsies were performed, out of which sickled erythrocytes were detected in 40 cases. The mean age at death was 30 years and a male/female ratio of 3:1 and peak mortality was in the 2 nd and 3 rd decades of life. The common causes of death in this study include vaso-occlusive crisis (45%), infection (40%). The terminal infection was heralded by upper respiratory tract (43.7%) and by gastroenteritis (31.2%). Other causes of death included intracranial haemorrhage (2.5%) and cirrhosis (2.5%). Among the cases of SCD, 10% of deaths were non-haemoglobinopathy related such as fall (accidental), organophosphorus poisoning and snake bite. Conclusion: This study is to precise analysis of causes of death is needed to focus and improve morbidity and mortality in sickle cell disease especially in highly prevalent area and will impact on the overall survival of these patients.

Background: The objective of the study was to study the spectrum of pathological lesions in patients with lung mass and to study correlation between clinical findings, histopathological pattern and immunohistochemical stains in various biopsy specimen for differentiation and typing of tumors. Methods: This retrospective study was done for the period of three years at Department of Pathology, New Civil Hospital, Surat, India, which is a tertiary health care Centre. Here we studied 78 cases of lung biopsy received in formalin, which were subjected to histopathological examination. Immunohistochemistry was performed as and when required. Results: Total 78 lung biopsy specimens were examined. Out of which, 59 cases (75.6%) were neoplastic, 12 cases(15.4%) were non-neoplastic and 7 cases (9%) were inconclusive. The commonest histological type of malignancy was adenocarcinoma which is associated with peripheral mass lesion, female gender and in non-smokers. Commonest non-neoplastic lesion was tuberculosis. Malignancy was seen quite common in patients presented with lung masses in our institute. Conclusions: Lung tumours are quite common in patients presented with mass lesion. Similar to global trend, adenocarcinoma is the commonest histological type now and associated with change in incidence among women, in non-smokers, molecular alteration and prognosis which need further investigation. Immunohistochemistry is helpful in cases which are not accurately subtyped by histomorphology alone.

Background: : Immunohistochemistry play a very important role in modern surgical pathology especially for identification of tumors lacking the evidence of lineage differentiation on the basis of routine Hematoxylin and Eosin (H&E) stain alone. More than 90% of the tumor with diagnostic difficulties by routine H & E stain could be very well classified by using IHC. The aim of present study is to classify and identify MSRCT. Methods: The study was carried out in Department of Pathology, Government Medical College in a period from August 2008 to November 2011. Total 38 cases of MSRCT are selected for Immunohistochemical staining (IHC) and they are classified and categorized accordingly after IHC. Results: Out of 38 cases of MSRCT, there are 18 cases (47.36%) of non-Hodgkin lymphoma, 3 (7.89%) cases of Neuroblastoma, 3 (7.89%) cases of Synovial Sarcoma, 2 (5.26%) cases of Ewing Sarcoma, 2 (5.26%) cases of Undifferentiated neuroendocrine carcinoma, 2 (5.26%) case of Desmoplastic Small Round Cell Tumor, 1 (2.63%) case of Primitive Neuroectodermal Tumor, 1 (2.63%) case of Amelanotic Melanoma (Small cell variant), 1 (2.63%) case of Anaplastic Dysgerminoma, 1 (2.63%) case of Osteosarcoma, 1 (2.63 %) case of Wilm's tumor, 1 (2.63%) case of Dendritic cell Tumor Testis, 1 (2.63%) case of Undifferentiated Nasopharyngeal Carcinoma, 1 (2.63%) case of Embryonal rhabdomyosarcoma. Conclusions: IHC is very valuable tool for adequate and accurate categorization of MSRCT.
