Resumo:
The ameloblastoma is the most common odontogenic tumors, being locally invasive
and presenting high relapse rates. It has slow growth and minimal symptoms, and
hardly noticed in its early stages. It occurs in all age groups and is often diagnosed in
the third and fourth decades of life. It is rare in young patients, speculating that by
slow growth, probably, the lesion begins to develop in childhood, just being
diagnosed late years later. The unicystic variant is more common in pediatric patients
presenting radiographically as a cyst, and usually being diagnosed in
histopathological examination of a lesion removed or subjected to surgical biopsy as
an odontogenic cyst. Treatment of unicystic ameloblastomas have a less aggressive
character, and often affect pediatric patients, it is usually by a conservative approach
as enucleation, removal, peripheral osteotomy and the use of cryotherapy or Carnoy
solution. This paper describes a case of ameloblastoma uncicístico in a young
patient, located in the region of molars and mandibular branch right, with 17-month
follow-up. The clinical and radiographic diagnosis was odontogenic cyst, however
histopathological examination revealed that it was a unicystic ameloblastoma. The
proposed treatment was curettage with margin held through peripheral osteotomy
and Carnoy solution.
