Thoracic duct (TD) cyst is an uncommon abnormality that can be manifested as a cervical swelling. Pathogenesis includes congenital or degenerative weakness of the wall of the TD and obstruction of the lymphoid flow. Diagnosis is crucial to eliminate malignant disease or vein thrombosis and can be established by imaging and needle aspiration. We report a case of recurrent cervical swelling with spontaneous chylothorax and chyloperitoneum. A TD cyst with a terminal obstruction of the TD was diagnosed on lymphangiography. Treatment by microsurgical lymphovenous anastomosis was successful, and the patient was free of symptom 3 years later.

We report a case of intercostal muscle flap used in tracheobronchial reconstruction for extensive necrosis after burn lesions of the posterior wall. A 32-year-old man attempted suicide by ingestion of caustic material. He underwent emergency total esogastrectomy, tracheostomy, and feeding jejunostomy. Ten days later, endoscopy showed complete destruction of the membranous trachea, extending from the tracheostomy to the carina. Reconstruction was conducted with the patient under venovenous extracorporeal membrane oxygenation by use of a pedicled intercostal muscle flap. The patient was weaned from respiratory support on the 14th postoperative day. Examination of a biopsy specimen from the flap 7 months after tracheoplasty showed ciliated neoepithelium.
