Hybrid odontogenic tumors are rare conditions that can affect the oral maxillofacial region and usually occur in adults as an asymptomatic swelling. Hybrid odontogenic tumors exclusively involving adenomatoid odontogenic tumor (AOT) and calcifying cystic odontogenic tumor (CCOT) are rare, with only 4 reported cases. In addition, there are only few studies describing the presence of abortive enamel in AOT and, to our knowledge, CCOT was not present in any of them. We described a rare case of AOT associated with CCOT and abortive enamel formation in a 2-year-old child, a condition not well described in the international literature. Secretory cell activity was assessed by periodic acid-Schiff and Congo red stains.
混合性牙源性肿瘤是一种罕见的疾病，可累及口腔颌面部区域，通常发生于成年人，表现为无症状性肿胀。仅累及腺样牙源性肿瘤（AOT）和牙源性钙化囊性肿瘤（CCOT）的混合性牙源性肿瘤极为罕见，仅有4例报道。此外，仅有少数研究描述了AOT中存在发育不全的釉质，据我们所知，其中均未提及CCOT。我们报道了1例罕见的2岁儿童AOT合并CCOT及发育不全釉质形成的病例，这一情况在国际文献中鲜有描述。通过过碘酸-希夫染色和刚果红染色评估分泌细胞活性。
