Sarcoma in a Patient with Laryngeal Papillomatosis: A Case Report.

Introduction: Recurrent respiratory papillomatosis (RRP) is classically described as a benign neoplasm of the larynx. Nevertheless, transformation to dysplasia and invasive carcinoma can occur. Sarcoma of the larynx is rare.

Pancreatic resection for renal cell carcinoma metastasis: An exceptionally rare coexistence.

Introduction: Pancreatic metastases are uncommon and only found in a minority of patients with widespread metastatic disease at autopsy. The most common primary cancer site resulting in pancreatic metastases is the kidney, followed by colorectal cancer, melanoma, breast cancer, lung carcinoma and sarcoma.

Presentation Of Case: Herein, we report a 63-year-old male patient who presented -3.

Immunohistochemical evaluation of CXCL12-CXCR4 axis and VEGFR3 expression in primary urothelial cancer and its recurrence.

Aim: The aim of this study was to investigate the expression of CXC chemokine ligand-12 (CXCL12), CXC chemokine receptor 4 CXCR4 and of vascular endothelial growth factor receptor 3 (VEGFR3) in primary urothelial bladder carcinoma and their recurrence in relation to grade and pT status.

Materials And Methods: Immunohistochemistry was applied to 67 primary tumor (PC) sections and their recurrenct tumors (RC).

Results: The expression of CXCL12 both in PC and in RC was positively associated with tumor grade (p<0.
