Abstract:
We describe a case of spontaneous internal jugular vein thrombosis occurring as the first sign of occult lung cancer. The peculiarity of the case was the unusual site of thrombosis and the lack of risk factors for DVT (only a moderated reduction of protein S without inherited thrombophilia) as well as the absence of clinical signs of cancer. This report shows once again the strong association between idiopathic venous thromboembolism and cancer. Hypercoagulation tests confirmed the association between cancer and thrombophilia. Reduction of protein S has been discovered recently in patients with lung cancer but further data are required to confirm this finding. Combined treatment (chemotherapy and radiotherapy) associated with oral anticoagulation therapy was started in our patient at the moment of diagnosis.

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

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...
