RESUMO
Ameloblastomas are common in Niger. Their main risk is recurrence, which nearly always follows inadequate surgery: these tumors require radical excision followed with mandibular graft. A preoperative diagnosis is therefore indispensable. X-ras are non-specific. In Niger, the danger of osteomyelitis makes surgical biopsies dangerous. The attention is brought to the existence of gum lesions in 8 cases of ameloblastoma in Nigerian patients. Their biopsy may provide the diagnosis in quick and safe conditions.

Les auteurs presentent les differentes lesions kystiques et tumorales odontogenes sous forme d'une classification fondee sur leur histogenese et sur l'embryogenese des tissus dentaires. Les principaux caracteres radiologiques et anatomo-pathologiques etant definis de maniere nette et aisement memorisable; l'accent est mis sur la therapeutique et le pronostic; sachant que la premiere dicte le second et ne souffre pas d'errement. A cet egard; le probleme principal etant l'ameloblasme; les auteurs decrivent 7 observations d'une lesion gingivale originale; qui en permet aisement le diagnostic
