title: Operative wound implantation of inflammatory sarcomatoid carcinoma of the lung.
abstract: We describe a patient with iatrogenic chest wall implantation of inflammatory sarcomatoid carcinoma. A 43-year-old man underwent right partial lung resection for hemopneumothorax, with large bullae and an alveolar accumulation of histiocytes found on pathology. Three months later, a subcutaneous tumor appeared at a thoracoscopic port site. Needle aspiration of this tumor suggested a malignant neoplasm; therefore, a right upper lobectomy and chest wall resection were performed, and a pathologic diagnosis of sarcomatoid carcinoma was made. Pathologic reexamination of the original sample suggested that the tumor has been implanted in the patient's chest wall at the time of the first operation.
