Multiple Fibrolipomas of the Tongue: A Rare Case Report of a Pediatric Patient With Whole Exome Sequencing of the C2CD3 Gene.

Abstract

Multiple fibrolipomas of the tongue are rare benign tumors with a prevalence of 0.2% among both adults and children. Moreover, this lesion affecting an infant has not been reported in the literature. This is the first reported case of multiple fibrolipomas of the tongue in an infant. This case report describes the genetic sequencing and treatment of a 1-year-old child suffering from multiple fibrolipomas. Irregular growths on the anterior and lateral border of the tongue were reported by the mother of the child at the time of birth. The patient was presented to the hospital at the age of 1, and surgical excision of the lesions was performed under general anesthesia. The surgery was uneventful. Genetic sequencing was performed via whole exome sequencing, and two variants of the C2CD3 gene have been identified that may be associated with this condition, although causation has not yet been confirmed. Although this is a rare entity of the oral cavity, there are various differential diagnoses. Therefore, maxillofacial surgeons should perform histological diagnosis to confirm the findings. This is the first study in literature to understand the genetic sequencing of multiple fibrolipomas in an infant. Hence, the finding of this report can be utilized in further studies registering such cases.
