Abstract : Ameloblastoma is the most prevalent non- cancerous tumor originating from the dental epithelium. It arises in both the mandible and maxilla but with a higher occurrence in the posterior region of mandible. Ameloblastoma is characterized by its benign but locally aggressive features of a slow growing tumor ultimately causing expansion of the bone with displacement and resorption of surrounding structures. Herein, the authors describe a case report of a 22-years-old female who presented with an ulcerated and easy bleeding swelling on the left side of the midface which was clinically similar to a malignant tumor, however first histopathological diagnosis following incisional biopsy established the diagnosis of odontogenic myxoma, second phase incisional biopsy established the diagnosis of ameloblastoma all of which are benign lesions. The tumor was surgically removed and the defect was repaired by a rotational cheek flap to achieve satisfactory functional and cosmetic results. Clinical, radiological and pathological characteristics as well as surgical treatment approaches are further discussed. This was one of a kind unusual presentation of a maxillary ameloblastoma encountered in our setting.
