Spindle Cell Carcinoma of the Lung

Sarcomatoid carcinomas are rarely observed lung tumors. A 77-year-old male patient was admitted to our clinic with complaints of cough, anorexia, and weight loss. He had no history of smoking. A mass lesion in the lower lobe of the right lung was detected in the posteroanterior chest x- ray and thorax computed tomography. A fiberoptic bronchoscopy was performed. The biopsy result from the endobronchial lesion in the medial segment of the lower lobe in the right lung was consistent with spindle cell carcinoma of the lung. The patient was evaluated to have stage 3b non-small cell lung carcinoma and six cycles of chemotherapy were applied. An enlarged mass lesion and liver metastases were seen in the control thorax computed tomography at the sixth month of the therapy. We presented this case with spindle cell lung carcinoma as a rarely seen tumor with aggressive progression.
