Abstract

A 60 year old female with a family history of ovarian and breast cancer underwent a follow-up laparoscopic exploration which revealed peritoneal implants and mucinous deposits on the appendicular surface. The peritoneal implants were diagnosed as serous carcinoma with a characteristic immunophenotype, while the mucinous […]

Abstract:

Recently, the study of the EGFR mutations in lung cancer has become mandatory due to their usefulness in target therapy. Lately, the use of specific antibodies to study themost prevalent of these mutations has been introduced. The newly published discovery of the existence of a cross-reaction between […]
