Renal cell carcinoma (RCC) is the commonest malignant renal neoplasm. It is associated with multiple other primary neoplasms, like bladder, prostate, breast, colon, lung and non-Hodgkin lymphoma (NHL) which is a well-known factor; however, its concurrent detection with a gastrointestinal neoplasm is unusual but well acknowledged entity ¹. The prevalence of synchronous RCC and colonic malignancy is variable and its reported incidence in the literature usually varies between 0.03-0.5% ¹. The exact etiopathogenesis of these synchronous malignancies is not yet fully explained. It is postulated that synchronous malignancies affect the tissues having identical embryological roots ¹. Multiple synchronous malignancies occur when these tissues are exposed to certain carcinogens or environmental risk factors (alcohol, tobacco, ultraviolet light, pollution, hormonal factors, chemotherapy, & radiation exposure) ¹.
