HISTOPATHOLOGICAL SPECTRUM OF NEOPLASTIC LESIONS OF KIDNEY- A THREE YEARS STUDY

Abstract

Background: Kidney can be involved in various pathological process. Both benign & malignant tumors can occur in the kidney. They arise from different components of renal parenchyma, notably tubular epithelium.¹ 99 percent of renal neoplasms are malignant, with renal cell carcinoma and wilm’s tumor being the most common². Men have higher incidence than women (approximately 1.6:1) and vast majority are diagnosed after 65 years of age.

Material and methods: Prospective and retrospective study from January 2017 to December 2019 in the Department of Pathology.

Results: The study comprised of 67 cases of neoplastic conditions, out of which 63 cases are malignant and only 4 cases were recorded as benign.

Conclusion: Malignant tumors far more common than benign lesions. In adults and older individuals, renal cell carcinoma was most common while among paediatric age group, wilms tumor was most common. Benign tumors were uncommon.
