The World Health Organization (WHO) classifies odontomas as odontogenic tumors, consisting of odontogenic epithelium and ectomesenchyme. They result from developmental abnormalities and, therefore, do not constitute authentic tumors. It is a local malformation that has no growth autonomy. They are rarely symptomatic and are usually discovered accidentally during the realization of a radiographic examination. There are two variants of odontomas: complex and compound. Complex odontomas are made of a mass consisting of an anarchic assembly of mineralized tissue (enamel, dentin, and cementum) and dental pulp; while compound odontomas are consisting of a set of small rudimentary teeth, assembling in clusters. They rarely show the features of both types together. The aim of this work is to report a rare presentation of an odontoma in a 24-year-old male patient, which present the characteristics of both complex and compound variants. Surgical excision of the lesion was performed. Anatomopathological examination confirmed the diagnosis. Clinical and radiological survey does not show any recurrence.
世界卫生组织（WHO）将牙瘤归类为牙源性肿瘤，由牙源性上皮和外间充质组成。它们是发育异常的结果，因此并不构成真正的肿瘤。它是一种局部畸形，没有生长自主性。它们很少有症状，通常在进行影像学检查时偶然发现。牙瘤有两种变体：复合性和组合性。复合性牙瘤由一团由矿化组织（釉质、牙本质和牙骨质）和牙髓无规则聚集而成的肿块组成；而组合性牙瘤则由一组小的原始牙齿成簇聚集而成。它们很少同时表现出两种类型的特征。这项工作的目的是报告一名24岁男性患者罕见的牙瘤表现，其呈现出复合性和组合性变体的特征。对病变进行了手术切除。解剖病理学检查证实了诊断。临床和影像学检查未显示任何复发情况。
