We present a case of a 20-year-old woman presenting initially with an asymptomatic palatal swelling. Radiographic examination showed a cyst at the right maxilla with bucco-lingual expansion and perforation of palatal bone. Incisional biopsy was carried out via a buccal approach and the result revealed a benign odontogenic cyst, in keeping with radicular cyst. The patient was then scheduled for cyst enucleation. During the procedure, it was found that the palatal lesion was unrelated to the maxillary cyst. Incisional biopsy of the palatal mass was carried out and revealed a low-grade mucoepidermoid carcinoma. The patient then had a partial maxillectomy with fibula flap reconstruction. There was no recurrence at postoperative 1 year follow-up and she was rehabilitated with dental implants.
我们报告一例20岁女性患者，最初表现为无症状的腭部肿胀。影像学检查显示右侧上颌骨有一个囊肿，伴有颊舌向扩展及腭骨穿孔。通过颊侧入路进行了切开活检，结果显示为良性牙源性囊肿，符合根尖囊肿。随后该患者被安排进行囊肿摘除术。在手术过程中，发现腭部病变与上颌囊肿无关。对腭部肿物进行了切开活检，结果显示为低级别黏液表皮样癌。该患者随后接受了部分上颌骨切除术及腓骨瓣重建术。术后1年随访未见复发，她接受了牙种植修复。
