1 Unilateral or bilateral agenesis of the submandibular glands is extremely rare.

2 Unilateral submandibular gland agenesis is typically asymptomatic and discovered incidentally through imaging of the neck. Bilateral agenesis is more likely to produce symptoms in affected patients such as xerostomia, dysphagia, and dental problems.

3 Submandibular gland agenesis may be accompanied by genetic syndromes such as Treacher Collins syndrome, hemifacial microsomia, ectodermal dysplasia, and lacrimo‐dento‐digital syndrome.

4 Physical examination of the neck might not disclose unilateral or bilateral agenesis of the submandibular glands. It becomes necessary, therefore, to examine the oral cavity where the unilateral Wharton duct opening may not be present. CT or MR imaging of the neck will unequivocally establish the diagnosis of agenesis of the submandibular gland as this case demonstrated.
