  • Title: [A case of invasive thymoma displaying endobronchial and endocaval polypoid growth].
    Author: Ichimanda M, Okada S, Kai T.
    Journal: Nihon Kyobu Geka Gakkai Zasshi; 1991 Jun; 39(6):938-42. PubMed ID: 1894972.
    Abstract:
    The hens' egg-sized tumor connecting from anterior mediastinum to the hilus by chest radiography and chest CT was noted in a 63 year old female who complained of facial swelling and cough. The defect of the thumb tip-sized shadow was noted in the superior vena cava by superior vena cavography, and polyp covered with white coating obstructing the right apical bronchus was noted by fibrotic bronchoscopy, and malignant finding was obtained by biopsy of this polyp. After midsternotomy, a mass invaded to the superior vena cava and the right upper lobe was resected, and then superior vena cava was reconstructed by using supported polytetrafluoroethylene. The resected specimen revealed that the tumor extended not only to the pulmonary parenchyma with polypoid growth into the lumina of bronchi but also to the superior vena cava with polypoid growth. The patient was discharged at the postoperative radiotherapy with 40 Gy, and he is still alive free from the disease 3 years and 11 months after operation.
