Intranodal glue embolization for lymphorrhea following inguinal lymphadenectomy in penile cancer: A case report.

An 86-year-old man underwent total penectomy and bilateral inguinal lymphadenectomy (ILND) for penile cancer with an enlarged right inguinal lymph node. The accumulation of 100-150 ml of lymphatic fluid was observed in the right inguinal drain in a day after surgery. Compression was performed, without any improvement in lymphorrhea.

Differential treatment responses to immune checkpoint inhibitor (ICI) therapy in a case of multiple primary malignancies: the programmed death ligand-1 (PD-L1) negative ureteral and lung metastasis from a clear cell renal cell carcinoma appearing after robotic-assisted partial nephrectomy progressed after ICI therapy, while synchronous PD-L1-positive primary lung squamous cell carcinoma responded very well to ICI therapy: a case report.

Background: Renal cell carcinoma (RCC) and non-small cell lung cancer (NSCLC) are representative malignancies that respond well to immune checkpoint inhibitors (ICIs). Research has been conducted to identify biomarkers, such as programmed death ligand-1 (PD-L1), that would allow the response to ICI therapy to be predicted; however, the complex tumor immune system consisting of both host and tumor factors may also exert an influence.

Case Presentation: Computed tomographic imaging (CT) incidentally revealed a left renal mass, and a left pulmonary nodule with multiple lymph node metastases (LNMs).
