Renal tumors comprise a diverse spectrum of neoplastic lesions with relatively distinct patterns in children and adults. Variety of both benign and malignant tumours arises from different components of the renal parenchyma, notably tubular epithelium. Majority of renal neoplasms are epithelial in origin and malignant in nature. This study aim plunges on the wide spectrum of renal tumours, to study the frequency of benign and malignant tumours correlating with respect to age and sex of the patients. A Total of 33 Cases of renal neoplasms diagnosed at the Department of Pathology, at Silchar Medical College and Hospital over a period of 5 years were reviewed.All adult renal tumours –nephrectomies received in surgical pathology as well as renal tumours which were diagnosed at autopsy cases were included. All inflammatory conditions were excluded from the study. Most common age of presentation of renal tumours is 5th decade (39.4%). Male to female ratio is 2.3:1. Most common benign tumour is angiomyolipoma (6.1%) and most common malignant tumour is renal cell carcinoma, clear cell type (57.6%). Left kidney is reported to be more effected with tumours than right kidney. Accurate diagnosis of most renal tumours is not possible before surgery and histopathological evaluation is essential. Majority of the renal tumors in our study comprised of malignant lesions. Wilms tumor was the most common childhood tumor and renal cell carcinoma was the predominant malignant tumour of kidney. Among the subtypes of RCC clear cell type was the most common.
