Abstract:
Esthesioneuroblastoma is a rare tumour, for which a multimodal approach, including a combination of surgery and radiation, appears to provide the best disease-free and overall survival. Well-known for its tendency for local recurrence and distant spreading by both lymphatic and haematogenous routes, the most common sites of metastases are lungs and bones, followed by liver, spleen, scalp, breast, adrenals and ovary. One single case of metastasis to the trachea has been reported in the literature. The case is reported here of a patient who developed metastatic esthesioneuroblastoma to the trachea 18 months after primary surgery and radiation therapy. The patient was treated by two subsequent N-YAG laser endoscopic resections and chemotherapy.

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...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
