Renal cell carcinoma has a complex and variable natural history. We report a case underlining this who presented concomitant renal cell carcinoma metastasis with pituitary and adrenocortical adenomas. A 62-year-old woman presented with visual loss. Imaging revealed a large sellar mass with suprasellar extension. Four years before, nephrectomy and adrenalectomy had been performed for a renal cell carcinoma with metastasis in a coexistent adrenocortical adenoma. Faced with progressive visual loss and the questionable pituitary pathology, the patient underwent trans-sphenoidal surgery. Due to profuse tumor bleeding, only a biopsy was possible. In a second operation, the patient underwent craniotomy with subtotal resection of the tumor. Histological examination of the specimen revealed a metastasis of the renal cell carcinoma and a pituitary adenoma. The case presented here and a review of the reports suggest that there are some differences between the clinical features and outcomes of metastases of renal cell carcinoma and those of pituitary gland metastases from other primary sites.

Precise and rapid disease detection is critical for controlling infectious diseases like COVID-19. Current technologies struggle to simultaneously identify viral RNAs and host immune antibodies due to limited integration of sample preparation and detection. Here, we present acoustofluidic integrated molecular diagnostics (AIMDx) on a chip, a platform enabling high-speed, sensitive detection of viral immunoglobulins [immunoglobulin A (IgA), IgG, and IgM] and nucleic acids.

Purpose: Identifying prognostic indicators for risk stratification in metastatic renal cell carcinoma (mRCC) is crucial for optimizing treatment strategies and follow-up plans. This study aims to investigate the prognostic role of the glucose-to-lymphocyte ratio (GLR) in patients with mRCC receiving tyrosine kinase inhibitors (TKIs) as first-line therapy.
Methods: A retrospective cohort study was conducted using data from the Turkish Oncology Group Kidney Cancer Consortium Database.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.

Objectives: Renal cell carcinoma (RCC) with extrarenal fat (perinephric or renal sinus fat) invasion is the main evidence for the T3a stage. Currently, computed tomography (CT) is still the primary modality for staging RCC. This study aims to determine the diagnostic performance of CT in RCC patients with extrarenal fat invasion.
