Acute biliary pancreatitis masking haemobilia due to a false aneurysm of the right hepatic artery after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy is a commonly performed surgical procedure. The postoperative course is often uncomplicated; however, complications like infection, biliary leakage, and bleeding and bile duct injury can occur. Here we report on a patient with common bile duct obstruction and haemobilia due to a false aneurysm of the right hepatic artery after laparoscopic cholecystectomy, masked by biliary pancreatitis, complicated by an infarction of the liver after embolisation.

Combined evaluation of the FAS cell surface death receptor and CD8+ tumor infiltrating lymphocytes as a prognostic biomarker in breast cancer.

Multiple studies showed the prognostic capacities of tumor-infiltrating lymphocytes (TILs) in triple-negative breast cancer (TNBC), but not in other subtypes. We evaluated tumor expression of FAS, a key receptor in T-cell mediated apoptosis, as possible explanation for this differential prognostic value of TILs. Furthermore, we evaluated the prognostic relevance of FAS, both as an independent biomarker and in relation to CD8-positive T-cell presence.
