Adenomatoid odontogenic tumour (AOT) is a rare benign odontogenic tumour characterized by a progressively slow growing pattern and symptomless behavior. The differential diagnosis between AOT and other odontogenic tumours, such as ameloblastoma, should be well conducted in order to avoid extensive ablative surgery. The present case report is of a 27 year old female who reported with a chief complaint of mild intermittent pain and a swelling which was gradually increasing in size, on the left mid-facial region since 6 months. Radiographic Investigations revealed a round uni-locular radiolucent image of an intra-osseous lesion with a well defined border in the left maxilla. The tumor was encapsulated and was attached with 2 impacted supernumerary teeth which were fused and shaped as maxillary premolars. The images also showed multiple impacted supernumerary teeth in the maxilla and mandible. The clinical and radiographic diagnostic hypothesis of Adenomatoid odontogenic cyst and a differential diagnosis of Dentigerous Cyst was given. Surgical enucleation of the lesion was done under General Anaethesia. The histological sections were consistent with AOT.
腺样牙源性肿瘤(AOT)是一种罕见的良性牙源性肿瘤,其特征为生长缓慢且无症状。为避免进行广泛的切除手术,应准确鉴别AOT与其他牙源性肿瘤,如成釉细胞瘤。本病例报告的是一名27岁女性,她主诉自6个月以来左侧面中部区域有轻度间歇性疼痛和逐渐增大的肿胀。影像学检查显示左上颌骨内有一个边界清晰的圆形单房性透射影像,为骨内病变。肿瘤被包膜包裹,并附着有2颗融合且形态如同上颌前磨牙的埋伏多生牙。影像还显示上颌骨和下颌骨有多个埋伏多生牙。给出了腺样牙源性囊肿的临床和影像学诊断假设以及含牙囊肿的鉴别诊断。在全身麻醉下对病变进行了手术摘除。组织学切片与AOT相符。
