  • Background: Renal medullary carcinoma (RMC) is an aggressive form of non-clear cell kidney cancer that typically affects young adults and is almost exclusively associated with sickle cell trait. Typical RMC patients tend to be young black males (2:1 male to female predominance) with sickle cell trait who present with pain and hematuria and are found to have metastatic disease at diagnosis. Prognosis is extremely poor, with a mean survival of less than a year in most cases.; Case Report: We present a case illustrative of many of the classic findings of RMC. A 25-year-old female with a past medical history of sickle cell trait presented to the emergency room with right-sided flank pain. Initially, a computed tomography (CT) scan showed only a benign-appearing cystic lesion 4.5 cm in diameter in the right kidney. Six months later, the patient re-presented with hematuria, lightheadedness, and dizziness. A repeat CT scan showed that the renal cyst had enlarged to 5.6 cm. The patient underwent a decortication and fulguration procedure that revealed malignancy in the wall of the cyst. She was given a series of treatments but experienced progressive disease and passed away 2 years and 8 months after metastatic diagnosis.; Conclusion: Neither systemic therapy nor radiation therapy has been found to be particularly efficacious in the treatment of RMC. As the underlying biologic mechanisms of RMC are further elucidated on a basic science level, we expect new translational research opportunities will emerge and novel treatment options will be developed for this rare and dismal disease.
