Renal medullary carcinoma, also known as RMC, is a rare cancer of the kidney that predominantly afflicts young people of African descent who carry the sickle cell trait, sickle cell disease, or other sickle hemoglobinopathies that can cause sickling of the red blood cells. The Mission of RMCRF is to provide a comprehensive guide of the latest research and treatments for Renal Medullary Carcinoma and Sickle Cell Disease. RMC is known to nearly exclusively affect young people of African ethnicity who carry sickle cell disease, sickle cell trait, or other sickle hemoglobinopathies. The diagnosis of RMC should be considered in all patients younger than 50 years with poorly differentiated carcinoma that arises from the renal medulla. Renal medullary carcinoma (RMC) is a rare and highly aggressive malignancy arising from the renal medulla and found mostly in patients with sickle cell trait. Initially it is very common for people with renal medullary carcinoma to be misdiagnosed with having kidney stones, bronchitis or a urinary tract infection. We offer programs that heighten awareness, educate and promote advocacy to increase public understanding, and ultimately a cure for RMC. Renal medullary carcinoma (RMC) is both a malignant and infrequent tumor of epithelial origin [1-4].RMC represents less than 0.5% of renal carcinomas [].Since its description in 1995 by Davis et al [], few cases and case series have been reported [].RMC usually affects older children or young adults with sickle cell trait or heterozygous sickle cell disease … Renal medullary carcinoma (RMC) is a highly aggressive malignancy arising from the collecting duct epithelium of the kidney. [5] Longer survival of beyond one year was reported in one patient[6] and of up to eight years in one individual whose tumor was well circumscribed and non-metastatic at the time of diagnosis,[10] suggesting that early detection could dramatically improve survival.

Radiographic examination demonstrated possible tumor masses in the brain, thorax and left kidney. [7] Carboplatin, gemcitibine, and paclitaxel provided a complete response in a patient with advanced disease. I cannot stress the importance of getting a second opinion because had my brother not researched for himself, he would not be here with us today. The incidence of small renal masses has steadily increased during the last few decades in the United States and globally. Renal medullary carcinoma, also referred to as the seventh sickle cell nephropathy, typically affects young African Americans with sickle cell trait, or, less frequently, patients with sickle cell disease. Renal medullary carcinoma is considered a separate entity from collecting duct carcinoma. It is highly aggressive, and most patients present with metastases at diagnosis. Due to the apparent propensity for the tumor to spread to the central nervous system, it has been suggested that prophylactic craniospinal irradiation should be considered.[9]. Renal medullary carcinoma is a very rare tumor with a dismal outcome that is presented mostly in young males, of African descent.

The patient has renal medullary carcinoma, a form of renal cell carcinoma associated with sickle cell trait. [8] The role of radiation is unclear; some tumors have shown a response to radiation. Believed to arise from the renal papillae or calyceal epithelium and may be triggered by chronic medullary hypoxia as a result of sickled red cells (Urology 2002;60:1083) Called the seventh sickle cell nephropathy (others: unilateral hematuria, papillary necrosis, renal infarct, nephrotic syndrome, pyelonephritis, inability to concentrate urine) African-descent adolescents and young adults with sickle cell hemoglobinopathy are the most affected groups. In a case series of 34 patients, Davis and colleagues reported the following signs and symptoms:[citation needed], Other researchers have reported a palpable renal mass[1] or enlarged lymph nodes. Although renal medullary carcinoma (RMC) is a rare subtype of kidney cancer, it is particularly devastating in that it is nearly uniformly lethal. Therefore, early diagnosis of renal medullary carcinoma requires a high level of suspicion [ 3, 5 ]. Association with sickle cell trait. Renal cell carcinoma (RCC), also called renal cell cancer or renal cell adenocarcinoma, is a common type of kidney cancer.
