Abstract:
A collision tumor is a rare entity consisting of 2 different tumors that, because of proximity, merge together. The diagnosis of a collision tumor requires that the 2 tumors be histologically distinct. This phenomenon has been described mostly at the esophagogastric junction, where a squamous cell carcinoma of esophageal origin collides with a gastric adenocarcinoma. The present case is of 2 histologically distinct tumors with aggressive features occurring at the mediastinum.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
