Introduction: Cervical cancers are the second most frequent type of cancer in females. It develops from premalignant to invasive stages in a multistep process of carcinogenesis. The differentiation between cervical intraepithelial neoplasia III (CIN III) and early squamous cell carcinoma (SCC) of the cervix could be difficult to diagnose in certain situations unless we see the invasion. The objective of the study was to determine the expression of p53 & Ki67 in CIN and cervical cancers and its correlation with grading and differentiation of cervical cancers with special emphasis on whether the use of Ki67 & p53 markers could help in differentiating CIN III from early SCC. Material and Methods: A prospective study on 90 cases of cervical biopsies, including-cases of : chronic cervicitis (40), CIN III (19) and invasive carcinoma (31). All cases were evaluated by immunohistochemistry using Ki67 & p53 monoclonal antibodies. Results: Both Ki67 & p53 showed higher expression in CIN III and invasive cervical carcinoma than chronic cervicitis with statistically significant difference p<0.01 and p<0.001 respectively. High significant difference of p53 & Ki67 expression was found between patients with CIN III and invasive cervical carcinomas. There was a clear trend for increasing number of cases with positive Ki67 & p53 index with increasing grades of cervical cancer. Conclusion: Ki67 & p53 showed increased expression from CIN III to SCC and it may be helpful adjunct in differentiating these two lesions. These markers could be used as biomarkers in the evaluation of the proliferative activity and progressive potential of dysplastic and neoplastic changes.
The development of testes occurs in the abdomen during fetal life, after which they migrate into the scrotal sacs during the third trimester. During their descent, they may get arrested anywhere along the tract. Risk of testicular cancer is higher in patients with undescended testes, abdominal testis being more prone than inguinal. Seminoma is the commonest cancer in undescended testis. However, synchronous seminoma involving bilateral cryptorchid testis is rare. Present case is uncommon due to synchronous involvement of abdominopelvic and inguinal testes in extended age. It also exhibited unusual morphology with marked heterogeneity grossly as well as microscopically, instead of a common homogenous appearance.
Background: Minor salivary gland benign tumors constitute a very small fraction of salivary gland tumors. The majority of monomorphic adenomas arise from the main salivary glands but rarely these can arise from the minor salivary glands of the buccal mucosa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
