Extracranial meningioma is very rare with few cases reported, especially in the oral cavity. Its diagnosis is considered a challenge owing to the unusual site of occurrence. We report, to the best of our knowledge, the first case of extra-cranial meningioma as a primary tumor in the hard palate with no detected intracranial extension. A 59-year-old Egyptian female patient presented with a 22-year history of a large painless swelling at the right side of the hard palate, which could not be seen on radiographs. An incisional biopsy was taken and, after assessment with a panel of immunohistochemical markers, the lesion was diagnosed as extracranical grade I mengiothelial meningioma. The patient did not show up for surgical excision and follow-up was not performed because of the lose of contact with the patient. Intraoral meningioma is a rare tumor. Immuohistochemical markers are important for confirming this diagnosis.

Introduction: Primordial odontogenic tumors are a rare recently described mixed odontogenic tumor composed histopathologically of dental papilla like tissue and enamel organ like tissue. Only nine cases have been documented worldwide and we are reporting the tenth case which is from Egypt. Clinical finding: A 2-year-old Egyptian boy that presented with an asymptomatic swelling of the mandible which appeared with multilocular radiolucency associated with an impacted developing tooth on a computerized tomography (CT) scan. Diagnoses, interventions, and outcomes: The lesion was excised and diagnosed as a primordial odontogenic tumor. The patient was followed up for two years with no recurrence. Conclusion: Differentiation of primordial odontogenic tumors from other odontogenic tumors, which resemble it histopathologically is crucial to avoid unnecessary aggressive treatment.
