title: Cervical lymphadenopathy in young children: case report of nontuberculous mycobacterial infection.
abstract: A four-year-old male presented with right-sided facial swelling near the angle of the mandible. Despite the presence of multiple dental carious lesions, the cervical lymphadenopathy did not appear to be of dental origin. Otolaryngology referral with subsequent excision of the affected lymph nodes confirmed the cervical lymphadenopathy to be due to a Mycobacterium avium intracellulare infection. A two-year follow-up showed successful resolution of the condition. The purpose of the present report was to describe a case with multiple dental carious lesions and cervical lymphadenopathy, with the latter attributed to a nondental etiology. A differential diagnosis of nondental etiologies of cervical lymphadenopathy in young children is described.
