We report a rare case of synchronous presentation of nasopharyngeal and renal cell carcinomas in a-50-year old male patient with long standing smoking history. The patient was initially presented with a diagnosis of nasopharyngeal carcinoma. During staging process, the abdominal computed tomography detected a right renal solid mass, 6.5 cm in diameter, originating from posterior portion of the right renal cortex. Right radical nephrectomy was performed and pathological examination revealed renal cell carcinoma. Smoking was thought to be a risk factor for both cancers. Systemic evaluation of kidney should not be discarded in patients diagnosed with nasopharyngeal carcinoma living in western countries with a smoking history.

In the past decade, the use of immune checkpoint therapy (ICT) has increased across many malignancies, including metastatic renal cell carcinoma as an option for frontline and subsequent lines of therapy. Despite the many therapeutic benefits of ICT, its use is complicated by the potential risk of immune-related adverse events (irAEs). One rare but potentially life-threatening irAE is hemophagocytic lymphohistiocytosis (HLH).

Pulmonary arterial hypertension (PAH) is a rare and potentially fatal condition characterized by progressive increases in blood pressure in the arteries of the lungs. Oral selexipag, approved by the Food and Drug Administration (FDA) in 2015 for the treatment of PAH, targets prostacyclin receptors on pulmonary arterial vascular smooth muscle and endothelial cells to improve blood flow through the lungs and reduce pulmonary vascular resistance. Oral selexipag is effective, but may be discontinued due to factors like side effects, emergency conditions, or inability to take oral medication, potentially leading to severe adverse events, such as rebound pulmonary hypertension and right heart failure.

Dipeptidase 1 (DPEP1), initially identified as a renal membrane enzyme in mature human kidneys, plays a pivotal role in various cellular processes. It facilitates the exchange of materials and signal transduction across cell membranes, contributing significantly to dipeptide hydrolysis, glucose and lipid metabolism, immune inflammation, and ferroptosis, among other cellular functions. Extensive research has delineated the complex role of DPEP1 in oncogenesis and tumor progression, with its influence being context dependent.

Background: In renal cell carcinoma (RCC), skin metastases (SMs) occur in only 3.3% of cases and are even rarer as an initial manifestation of the disease. Although combination therapy with immune checkpoint inhibitors (ICIs) and targeted agents is the current standard of care, access to these treatments may be limited in certain regions due to cost constraints.

Background: Transitional cell carcinoma (TCC) of the renal pelvis is a rare cancer within the urinary system. However, the prognosis is not entirely satisfactory. This study aims to develop a clinical model for predicting cancer-specific survival (CSS) at 1-, 3-, and 5-year for White Americans with renal pelvic TCC.
