Epulis is an inflammatory or reactive hyperplasia of the gingiva, and commonly occurs in the oral region. However, epulis osteoplastica （peripheral ossifying fibroma） is a relatively rare disease. We report the case of a massive epulis osteoplastica covering the palate.
The patient was a 75-year-old woman who came to our clinic because of a palatal tumor. The tumor measured 60 × 50 × 20 mm and was elastical hard and pedunculated. A radiopaque area was found on radiographic examination. The clinical diagnosis was epulis osteoplastica, and gingival tumor excision was performed under general anesthesia. The histopathological diagnosis was peripheral ossifying fibroma （epulis osteoplastica）. As of 17 months after the operation, there has been no recurrence, and oral function is good.
