OBJECTIVE
Primary malignant odontogenic tumors in the suprasellar region have rarely been reported.
CLINICAL PRESENTATION
A partially cystic tumor that originated from the stalk and showed rapid enlargement was observed in a 56-year-old woman.
INTERVENTION
Gross total removal of the tumor was performed with sacrifice of the stalk. The tumor was a malignant epithelial type with odontogenic features, whereas findings consistent with craniopharyngioma were absent. The tumor recurred 14 months after surgery.
CONCLUSION
The present unusual tumor may represent a novel member of malignant tumors of the suprasellar region. Given the common embryological origin of craniopharyngiomas to odontogenic lesions, a possible correlation with craniopharyngioma was suggested.
目的
鞍上区原发性恶性牙源性肿瘤鲜有报道。
临床表现
在一名56岁女性中观察到一个起源于柄部并迅速增大的部分囊性肿瘤。
干预措施
在牺牲柄部的情况下对肿瘤进行了全切除。该肿瘤为具有牙源性特征的恶性上皮型，而未发现与颅咽管瘤一致的表现。肿瘤在术后14个月复发。
结论
目前这种不寻常的肿瘤可能代表鞍上区恶性肿瘤的一个新成员。鉴于颅咽管瘤与牙源性病变有共同的胚胎学起源，提示其与颅咽管瘤可能存在相关性。
