||P.215 2nd paragraph: "Renal medullary carcinoma (RMC) is a very rare malignancy that accounts for less than 1% of all renal neoplasms [BNID 113715]. RMC exhibits a highly aggressive behavior and is usually seen among young men aged between 10 and 40 years. Most patients are young African-American men [ref 2]. RMC occurs in the right kidney of more than 75% of the patients. The reported patients were associated with sickle cell hemoglobinopathy, mainly with sickle cell trait and less frequently without sickle cell disease [ref 3]." P.218 left column 2nd paragraph: "RMC is a very rare aggressive malignancy that affects all age groups. RMC has a poor survival because metastatic disease is almost universal at the time of diagnosis, with a median survival of about 4 months. It typically presents in young African patients with sickle cell trait or disease, with the involvement of the right kidney characteristically in over 75% of the cases."
