分析５例牙源性腺样瘤的临床病理及该肿瘤的组织来源，报道１例来源于牙源性囊肿衬里上皮的牙源性腺样瘤，建议将发生于牙源性囊肿壁上的牙源性腺样瘤称为壁性牙源性腺样瘤．其诊断的依据是在切片中看到囊肿衬里上皮增生并移行为牙源性腺样瘤，两者之间有明确的延续关系．或在同一切片中看到典型的囊壁及肿瘤成份．并进一步讨论了壁性牙源性腺样瘤与牙源性腺样瘤囊性变的鉴别诊断 Analysis of 5 cases of odontogenic adenoid tumor clinicopathological and tissue sources of this tumor was reported in 1 case of odontogenic adenoid derived from the lining of odontogenic cysts, it is proposed that the odontogenic gland occurs in the wall of the odontogenic cyst Athyroid tumor called odontogenic adenoid. The diagnosis is based on the cyst lining in the epithelial hyperplasia and migration to the source of adenoid, there is a clear continuation of the relationship between the two. Or in the same slice to see the typical wall and tumor components. And further discussed the differential diagnosis of cystic degeneration between odontogenic adenoid and odontogenic adenoid
