Abstract
Roentgenographically occult squamous cell carcinoma (ROSCC) was reported to have been cured after complete resection. We experienced unusual local and distant metastases after complete resection of a ROSCC of left B6 bronchus. During the operation due to the proximal bronchial stump being positive for squamous cell carcinoma (SCC), a left lower sleeve lobectomy was performed. Six years after the operation, a chest CT showed no abnormal shadows. 6Â months later a PET-CT showed metastases on bilateral supraclavicular lymph nodes, mediastinal lymph nodes, and the right adrenal glands. A biopsy of the right supraclavicular lymph node revealed that it was a metastatic SCC. The possibility of recurrence from a second pulmonary SCC might still remain. A prolonged follow-up over many years is desirable for a heavy smoker with a ROSCC.
