The case of a 49-year-old man with multiple pleuropericardial implants of B2 thymoma is reported. Two years earlier, the patient had undergone left videothoracoscopic (VATS) resection of a 6-cm thymoma in another hospital. The operative report describes a technically correct procedure with morcellation of the lesion within a retrieval thoracoscopic bag. Through a standard thoracotomy, 11 implants were resected with macroscopically complete tumor removal. The origin of cell spillage was ascribed to manipulation of the thymoma during VATS resection.
