An idiopathic severe macroglossia in a young adult patient: a rare case.

Macroglossia, an uncommon anatomical anomaly, can manifest as either congenital or acquired. The size of the tongue undergoes variations with age, peaking at 8 years and reaching full maturity at 18 years. Congenital macroglossia stems from diverse conditions, such as muscular hypertrophy, hemangioma, lymphangioma, Down syndrome, and others. Acquired macroglossia can result from malignancies, endocrine and metabolic disorders, chronic infectious diseases, and head and neck infections, among other factors. Additionally, extended-prone surgery can lead to its development. The incidence of macroglossia is likely underreported. This presentation is rare with only six reported cases in the literature.
