Background: Difference between the benign and malignant counterparts of mesenchymal tumours is significant due to the differences in the clinical outcome and the role of the surgical pathologist in making this distinction (especially in difficult cases) cannot be underestimated.2 The aim of the current study is to evaluate the histomorphological features of mesenchymal tumours of uterine corpus. Materials and methods: was undertaken in the Department of Pathology, JJM Medical College, Davangere over a period of two years from July 2010- June 2012. Results: Out of the 492 cases, majority were benign tumours accounting to 485(98.58%) cases, followed by 6(1.22%) cases of malignant tumours and one (0.20%) smooth muscle tumour of uncertain malignant potential (STUMP). Conclusion: Differentiation between the benign and malignant counterparts of mesenchymal tumours is through the use of multivariate criteria; that is, criteria that involves several microscopic features such as differentiated cell type , presence and type of tumor necrosis, the degree of cytologic atypia, the mitotic index, and the relationship to surrounding normal structures, including extrauterine sites. Morphological features supported by proper usage of IHC markers will help in arriving at the final diagnosis.
