Inflammation of the glands and tissues of the pharynx (throat), including the adenoids and other lymphoid tissue.
From Greek 'aden' (gland) + 'pharynx' (throat) + '-itis' (inflammation suffix). This clinical term emerged to distinguish throat inflammation that specifically involves glandular tissues from simple pharyngitis.
Kids get adenopharyngitis far more often than adults because their immune systems are still learning to fight infections, and those adenoid glands swell up dramatically—by adulthood, adenoids shrink, which is why you rarely hear about this condition in older people.
