ABSTRACT
El ameloblastoma es un tumor odontogénico benigno, localmente invasivo y recidivante, que constituye aproximadamente el 10% de los tumores odontogénicos. Estos tumores ocurren más frecuentemente en la mandíbula. El cuadro clínico se caracteriza generalmente por presentar deformaciones faciales, crecimiento lento y asintomático. El tratamiento depende del tipo, la localización y el tamaño del tumor, así como de la edad del paciente. En este artículo se presenta un caso de ameloblastoma multiquístico en la mandíbula, que implica a una paciente del sexo femenino de 57 años, en el cual se discuten los aspectos diagnósticos e histopatológicos, así como el tratamiento menos invasivo empleado en el caso(AU)
Ameloblastoma is a benign odontogenic tumor, locally invasive and recurrent, representing approximately 10% of odontogenic tumors. The majority of cases occur in the mandible with slow and asymptomatic growth that can lead to facial deformities. The treatment of choice is based upon on the type, location and size of the tumor, as well as the age of the patient. A case of multicystic ameloblastoma of the mandible affecting a 57 years old female patient is presented discussing the diagnostic, histological, and less invasive treatment used in the case(AU)

Peripheral ameloblastoma is a rare odontogenic soft tissue tumor, derived from epithelial and/or mesenchymal elements being part of the tooth-forming apparatus. The lesion responses for approximately 1% to 5% of all cases of ameloblastoma affecting alveolar mucosa and gingiva occur, mainly, in the middle age. This article describes a case of peripheral ameloblastoma involving a 20-year-old male located in the (upper/lower, vestibular/buccal) gingiva. After the case presentation, clinical and microscopic findings are discussed.

Dermoid cysts of the floor of the mouth are rare lesions thought to be caused by entrapment of germinal epithelium during the closure of the mandibular and hyoid branchial arches. They usually present as a nonpainful swelling. This type of lesion occurs more frequently in patients between 15 and 35 years, but can be seen in all age ranges. Histologically, all dermoids are lined by epidermis. The contents of the cyst lining determine the histological categories of the cyst: epidermoid, if epidermis is lining the cyst; dermoid, if skin annexes exist; or teratoid, if there are tissues derivated from the three germinal layers. Anatomical classification is useful for surgical approach choice, intra- or extraorally. This report presents a case of a dermoid cyst of the floor of the mouth in a 12-year-old patient, and a review of all steps necessary for its diagnosis and treatment was made.
