Summary
Congenital tongue anomalies are rare, with fewer than 50 documented cases of lingual hypoplasia. This study details a newborn with an absent anterior tongue and micrognathia, contributing to understanding these rare conditions.
Area of Science:
- Developmental biology
- Pediatric medicine
- Medical genetics
Background:
- Congenital anomalies of the tongue are rare developmental conditions.
- Lingual hypoplasia, first described in 1719, has been reported in fewer than 50 cases.
- These anomalies are often associated with the hypoglossia-hypodactylia syndrome.
Observation:
- A case of a newborn presenting with congenital tongue anomaly is described.
- The newborn exhibited an absent anterior tongue and a rudimentary posterior tongue remnant.
- Associated micrognathia was also noted in the infant.
Findings:
- The case highlights a severe form of congenital lingual hypoplasia.
- The presentation includes both tongue malformation and mandibular hypoplasia (micrognathia).
- Discussion includes embryological origins and potential pathogenetic mechanisms.
Implications:
- This case expands the spectrum of known congenital tongue anomalies.
- Further research into the embryology of the tongue may elucidate pathogenesis.
- Understanding such rare conditions is crucial for accurate diagnosis and management in neonates.
