Abstract


RÉSUMÉ
Une patiente de 22 ans a été admise pour une tumeur du maxillaire à gauche découverte après avulsion dentaire. A l’examen, la tumeur était sous muqueuse, friable, saignant modérément au contact et franchissant la ligne médiane. La tomodensitométrie a montré un processus tumoral tissulaire du maxillaire, musculo-muqueux avec extension au plancher du sinus maxillaire et au palais osseux. La patiente a eu trois interventions chirurgicales pour récidive et extension tumorale locale. L’examene histologique a évoqué successivement une tumeur bénigne à cellules géantes puis un améloblastome. Le diagnostic de carcinome améloblastique a été établi à la quatrième intervention chirurgicale. Le traitement complémentaire a comporté six cures de chimiothérapie. La patiente était sans récidive avec un recul de 15 mois.

ABSTRACT
We report the case of a 22 years old female presenting a left maxillary tumor discovered after dental avulsion. On examination, the tumor was submucosal, friable, bleeding on contact and crossing the midline. CT scan showed a tissular process of the left maxillary, extending to the floor of the maxillary sinus and hard palate. The patient underwent three surgical procedures for tumor recurrence and local extension. Histological results firstly suggested a giant cell benign tumor then an ameloblastoma. The diagnosis of ameloblastic carcinoma was established after the fourth surgical operation. The patient had six chemotherapy sessions. Fifteen months after surgery, the patient had no recurrence.
