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. 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. The lesion was excised and diagnosed as a primordial odontogenic tumor. The patient was followed up for two years with no recurrence. Differentiation of primordial odontogenic tumors from other odontogenic tumors, which resemble it histopathologically is crucial to avoid unnecessary aggressive treatment.
原始牙源性肿瘤是一种最近才被描述的罕见混合性牙源性肿瘤，组织病理学上由牙乳头样组织和牙釉质器样组织组成。全球仅记录了9例，我们现报告第10例，该病例来自埃及。一名2岁的埃及男孩，下颌出现无症状肿胀，计算机断层扫描（CT）显示为多房性透射区，伴有一颗阻生的发育中牙齿。病变被切除，诊断为原始牙源性肿瘤。对该患者进行了两年随访，无复发。将原始牙源性肿瘤与其他组织病理学上与之相似的牙源性肿瘤区分开来，对于避免不必要的积极治疗至关重要。
