Mangoba3 aA case of a 37 year old female with a seven-year history of a huge left-sided maxillary mass is presented. Radiologic and CT findings along with the initial biopsies were suggestive of a Mucocele. Excision of the mass along with a Medial Maxillectomy was performed. The final histopathology is Ossifying Fibroma with a secondary Aneurysmal Bone Cyst. Characteristics of these and similar lesions as well as the surgical approach are discussed.  aActa Medica Philippina, 1999 35 (3 & 4) pages 36-42 2aFibroma, Ossifying 2aBone Cysts, Aneurysmal 2aMaxillary Sinus
