Which malignant tumor of the parotid gland is known for exhibiting perineural invasion?

Explanation

Among parotid gland malignancies, adenoid cystic carcinoma is distinguished by its tendency to invade along nerve sheaths, a process known as perineural spread. This characteristic differentiates it from other tumors such as pleomorphic adenoma, Warthin’s tumor, and ductal papilloma, which typically do not demonstrate this pattern.
