Research paper thumbnail of Prevalence of Testicular and Paratesticular Tumours: A 10-year Retrospective Study

National Journal of Laboratory Medicine, 2020

There is high incidence of testicular tumours in the western world compared to Asian and African countries. TGCTs occur at an early age compared to malignant tumours of other organs. Nonseminomatous germ cell tumours should be distinguished from seminomatous tumours because, the later have higher cure rate. Mesenchymal tumours are more common in paratesticular area. Aim: To know the prevalence of testicular and paratesticular tumours. Materials and Methods: This was a retrospective descriptional study done in Department of Pathology, NRI Medical College, Chinakakani, Guntur, Andhra Pradesh, India, over a period of 10 years from January 2010 to December 2019. The data such as age and histopathological diagnosis of testicular and paratesticular tumours were archived from the medical record...

Research paper thumbnail of A Five-Year Histopathological Review of CNS Tumours in a Tertiary Centre with Emphasis on Diagnostic Aspects of Uncommon Tumours

Journal of Evidence Based Medicine and Healthcare, 2016

These tumours show specific predilection for age and sex groups, more commonly than of tumours of other systems. Though tumours of glial tissue are more common, other tumours of neural, ependymal and meningeal origin are not uncommon. Metastatic disease is the common encounter in elderly. Tumour diagnosis is not always straight forward as many non-neoplastic lesions and reactive proliferations mimic tumours. Immunohistochemistry may help in problematic cases and thus can be used as an adjuvant tool in the diagnosis of such cases in addition to the routine histopathological staining methods. An accurate histological diagnosis is of extreme importance in these sites as exact diagnosis helps in proper management and favourable clinical outcome. MATERIAL & METHODS This study is on a retrospective and prospective basis in our institution from January 2011 to January, 2016. Our institute is a tertiary care center attached to a medical college catering to the needs of a rural based population. During this period, a total of 717 central nervous system tumour specimens were received and diagnosed based on examination of Haematoxylin and Eosin stained sections of formalin fixed and paraffin embedded specimens. Immunohistochemical markers (IHC) were applied in selective cases for an accurate diagnosis and a number of rare cases were diagnosed based on morphology and IHC marker studies. RESULTS Age and sex incidence and anatomic distribution of various tumours were studied. In adults, meningiomas occurred most frequently in the present study followed by nerve sheath tumours, astrocytomas, metastatic deposits, glioblastomas and pituitary adenomas. Embryonal tumours occurred frequently in children. Other rare tumours identified are amyloidogenic pituitary adenoma, central neurocytoma, glioneuronal tumour with neuropil-like islands, ganglioglioma, large cell medulloblastoma, rhabdoid and secretory meningioma, immature teratoma and gliosarcoma. Grading of the tumours was done according to the revised World Health Organization criteria. CONCLUSION In this study, we discuss the process of establishing accurately the diagnosis of central nervous system tumours including spinal tumours, with emphasis on rare tumours encountered and how IHC helped in the diagnosis.

Research paper thumbnail of Hashimoto′s thyroiditis associated Evans syndrome: A rare case report on the clustered autoimmune disease triad

Indian Journal of Endocrinology and Metabolism, 2013

Evans syndrome is a rare combination of autoimmune hemolytic anemia and immune thrombocytopenia. ... more Evans syndrome is a rare combination of autoimmune hemolytic anemia and immune thrombocytopenia. Their association with autoimmune thyroid diseases has been reported by few authors; however, a sequential development of the Evans syndrome in cases of Hashimoto's thyroiditis is extremely rare. The clustering of these autoimmune diseases might share a common pathogenic pathway. We present the fourth such case in world literature, of a 34-year-old female diagnosed with Hashimoto's thyroiditis in 2006, who has been taking synthetic thyroid hormone since then. Her condition is now clinically complicated with the development of the Evans syndrome.
