Consequently, oral surgeons should possess extensive knowledge regarding the etiology of cervical lymphadenopathy. The present article describes a case of a 60-year-old female who reported to the Department of oral medicine and oral surgery at the University Dental Clinic of Monastir- Tunisia with a complaint of painless swelling of 5 days duration on the right side of her neck, specifically in the jugular-carotid region. The oral examination revealed an infected right maxillary third molar, confirmed on the radiograph. Considering the possibility of neck swelling caused by reactive lymphadenitis secondary to an infected molar, removing the third molar on the right side was performed under antibiotic coverage, which was uneventful.

The patient remained free of the presenting symptoms 28 days later. As well as complete regression of the swelling.
