Degloving technique을 이용하여 양측성 상악골 절제술로 치료한 범랑아 세포암종(ameloblastic carcinoma)의 치험례

A case report of ameloblastic carcinoma treated with bilateral maxillectomy using degloving technique

This is a report of case about the ameloblastic carcinoma arising in both maxillary sinus regions of 50-year-old female patient after the maxillectomy because of unidentified odontogenic carcinoma 4 years ago. The ameloblastic carcinoma is defined as an ameloblastoma in which there is histologic evidence of malignancy in the primary tumor or the recurrent (or metastasis), regardless of whether it has metastasized and occurs exceedingly rare. The clinical course is aggressive with extensive local destruction and spread, frequent recurrences and occasionally metasized neck node. Histologic features generally resembled those of conventional ameloblastoma but with cytologic features of epithelial malignant disease. The most common sign is swelling, pain and rapid growth. The primary treatment should be accomplished by complete resection rather than by palliative operative procedures or radiotherapy. In this case, the authors treated successfully with bilateral maxillectomy via the midfacial degloving technique and Lt. side RND.
