Odontogenic tumours are neoplasms developed exclusively in maxilla and mandible, arise from the epithelial component or the mesenchyman. They account for minimum percentage of all oral cavity tumors, represent between 5 % and 8 %. Mostly are benign neoplasms only 5 % are malignant. Clinico-pathological features, radiological findings and outcomes: odontogenic myxoma, primary intraosseous carcinoma and one ameloblastic carcinoma are presented. Odontogenic neoplasm derived from the odontogenic apparatus or its cellular remnants comprise a morphologically heterogeneous group of tumors that affect the oral and maxillofacial region. Most common histological types are the complex and compound odontomas (65 %), followed by ameloblastoma with 11 %, adenomatoid odontogenic tumour with 3 % and odontogenic myxoma. Our review comprises two malignant tumors and one benign. Odontogenic tumors are rare we must consider them in the differential diagnosis in maxilla and mandible tumors. Wide surgical resection with oncologic margins is the treatment of choice.
