Of all primary renal neoplasms, 80-85% are renal cell carcinomas (RCCs), which develop in the renal cortex. There are more than 10 histological and molecular subtypes of the disease, the most frequent of which is clear cell RCC, which also causes most cancer-related deaths. Other renal neoplasms, including urothelial carcinoma, Wilms' tumor, and renal sarcoma, each affect a particular age group and have specific gross and histological features. Due to the genetic susceptibility of each of these malignancies, early mutation discovery is necessary for the early detection of a tumor. Furthermore, it is crucial to avoid environmental factors leading to each type. This study provides relatively detailed and essential information regarding each subtype of renal carcinoma.

Transgender individuals experience lower overall health outcomes than cisgender individuals due to a higher burden of chronic illnesses in this demographic. An early loss in renal function is frequently seen in acute interstitial nephritis (AIN), which is defined by the presence of inflammatory infiltrates and edema inside the interstitium. Infections or medication use can cause interstitial nephritis. In two-thirds of cases, interstitial nephritis caused by drugs is detected. Few people are affected by it, thus, it's thought to be immune-mediated rather than dose-dependent. In this report, a 32-year-old transgender female was admitted to a hospital due to generalized swelling following filler injections in the buttocks region.It is important for doctors and patients to be informed about these procedures' potential risks. Additionally, more study has to be done on the negative effects of filler injections.
