Volume 23, Number 4Kidney CancerImaging Techniques in the Diagnosis of Renal Cell Carcinoma: Contemporary Trends and Future DirectionsGautam JayramIncreasing radiographic detection of incidental small renal masses has led to a growing concern regarding overtreatment of these lesions. Given the limitations of computed tomography and magnetic resonance imaging, there is an unmet need for improved kidney imaging techniques that can provide more accurate assessments of renal lesions. This review provides a summary of established kidney imaging modalities and also those likely to be meaningful in the near future. Kidney imaging has evolved, with several modalities contributing to the overall diagnostic landscape. There is great optimism that a new era of molecular imaging in renal cell carcinoma can vastly improve diagnostic capabilities and limit unnecessary invasive procedures.Carcinoma, renal cellCarcinomaKidney neoplasmsmolecular imagingpositron-emission tomography
Volume 23, Number 3Kidney CancerResponse to Targeted Therapy and Checkpoint Inhibition in a Patient With Mucinous Tubular and Spindle Cell Carcinoma: A Case Report and Literature ReviewRuchi AgarwalDaniela V. CastroYu Jun LiJaya GoudSalvador Jaime-CasasMucinous tubular and spindle cell carcinoma (MTSCC) is a form of renal cell carcinoma characterized by its tubular structure, mucinous stroma, and spindle-shaped cells. It makes up less than 1% of all renal cell carcinoma cases and has been classically described as indolent, although the disease course varies. Here we analyze the case of a 67-year-old woman with metastatic MTSCC with a sarcomatoid component. The course of treatment was extensive and included targeted therapy and immunotherapy. Thus, this case review offers insight into the heterogeneous clinical course of MTSCC and potential therapeutic options for these patients.Immunotherapyimmune checkpoint inhibitorsCarcinoma, renal cellCarcinomaneoplasms, squamous, mucinous, and serouscarcinoma, tubular
