Results of. An indolent but aggressive tumour. Braz J Otorhinolaryngol. Warthin tumor is the 2nd most common benign lesion. The tumor usually presents as a slow-growing mass and tends to spread along nerve sheaths. The incision is made where it is less likely to leave a noticeable scar: either in a crease of the neck or hidden along the earlobe and hairline, similar to the approach used in a face-lift. In the parotid, this may threaten local structures and so prompt surgical intervention is required.
