Long-term observation of a case of infantile ameloblastoma leading to eruption of the impacted permanent teeth by enucleation and marsupialization

A radiographic examination of a 6 -year-old girl revealed a monolocular radiolucent area involving the dental germ of lower first molar. The lesion was about the size of a hen's egg and was located at the right side of the mandible. After histological examination of bits of tissues removed from...

Summary:A radiographic examination of a 6 -year-old girl revealed a monolocular radiolucent area involving the dental germ of lower first molar. The lesion was about the size of a hen's egg and was located at the right side of the mandible. After histological examination of bits of tissues removed from the region, the case was diagnosed as ameloblastoma. Enucleation with an open wound was performed repeatedly. The radiolucency disappeared, and the lower first molar erupted when the patient was 8 years old. At the age of 10 years and 10 months, the lower second molar and the premolar also erupted. However, at 16 and 20 years of age, she had recurrences of the tumor. Eventually, the patient underwent extraction of the lower second molar and extirpation of the tumor. The patient, now 21 years old, is doing well, with no symptoms of clinical disturbances.
