The tumor (TU) is 34 mm × 28 mm in size, has well-delineated borders and a hypoechoic, homogeneous echo pattern. A needle passing through the pharyngeal wall into the tumor is visible. ▶ Fig. 4 Specimen obtained by EUS-guided fine-needle biopsy under 100 × magnification. Typical appearance of a pleomorphic adenoma of the parotid gland with epithelial, myoepithelial, and stromal components. Hematoxylin and eosin stain. ▶ Fig. 2 Schematic drawing of the anatomy of the mouth and throat (midsagittal plane), showing the position of the echoendoscope during endoscopic ultrasound (EUS) examination and fine-needle biopsy of the tumor.
