Figure 9. CT-guided needle biopsy of the left lung, upper lobe, showed A) lung parenchymal infiltration by a spindle cell malignant neoplasm with pleomorphic cells that are morphologically similar to the patient's prior known diagnosis of pleomorphic/dedifferentiated leiomyosarcoma, FNCLCC grade 3, (100X, H&E)​. B) tumor cells with bizarre nuclei and surrounding stromal hyalinization (400X, H&E).
