Slowly enlarging, nontender mass in the right submandibular region

Slow-growing, soft tissue masses in the submandibular region of the neck frequently are caused by tumors of the submandibular salivary gland. These neoplasms are most commonly benign and characteristically develop during a prolonged period--often, during 15 or more years. The recommended treatment is excision of the gland, and, if adequately performed, the probability of the tumor's recurring is insignificant.
