Representative images of the FNA smears and cellblock material were shown in Fig. 6 .39a-d.The cytological features raise a differential diagnosis that includes neuroendocrine tumor, spindle cell tumors, including sarcomatoid carcinoma and metastatic melanoma of the spindle cell type.	./cache/cord-024141-9sdbhw2g.txt	./txt/cord-024141-9sdbhw2g.txt
