Hamartoma is a congenital benign lesion commonly found in the lungs, kidneys, colon, and other regions, but it is seldom seen in the oral cavity. Multiple hamartoma occurrences in the tongue are particularly rare. This article describes a 7-day-old female infant with multiple tongue tumors and a cleft palate, who had difficulty feeding and subsequently underwent tumor removal under general anesthesia. Nine months later, a cleft palate repair was performed. No genetic abnormalities were detected in the genetic testing. After the tumor removal, follow-ups were conducted every year to observe any recurrence of the tumors, the morphology and function of the tongue, and any systemic abnormalities. After 7 years of follow-up, there was no recurrence of the tumors, and the morphology and function of the tongue were normal, with no systemic diseases found. It is crucial to conduct multidisciplinary consultations for children diagnosed with multiple tongue hamartomas and to monitor their overall development while addressing oral lesions.
