Non-smoking female with a new right upper lobe lung mass and three PET-positive mediastinal lymph nodes

The Case Continues
A first aspirate was done from the level 4L node. Rapid on-site examination was positive for malignancy, favoring adenocarcinoma. Using a 22-gauge needle, the second aspirate showed core tissue. Part of the core was placed in formalin for histopathology and part was placed in stabilizing solution to be later used for extraction of RNA and DNA.
