An epulis(plural: epulides) is a benign neoplasm derived from the periodontal ligament or connective tissue. They occur commonly in dogs [1]. Epulides can be classified into four types on the basis of histologic appearance: Fibromatous, ossifying, acanthomatous and giant cell [2]. Here we report a case of epulis that shows all features of fibromatous, ossifying and giant cell epulides simultaneously. (omitted)

An epulis was occurred on gingiva of 11-year old female dog, Yorkshire terrier. Our case had feature of ossifying epulis but there were a few multi-nucleated giant cells (MGCs). MGCs had osteoclast-like appearance and giant cell epulis usually appears at the site of tooth extraction. Therefore, we suggest that appearance of MGCs in our case may be due to phagocytosis pre-formed osteoid/bone or our case may be mixed epulides of ossifying and giant cell epulis by mixed stimulation of chronic gingivitis and trauma and in flammation by tooth extraction. Thus, MGCs have possibility enough to appear in ossifying epulis, but ossifying epulis accompanying MGCs has not been reported. Therefore, our case may deserves an attention as an unique case and will be helpful to study pathogenesis of giant cell containing lesion of the jaw.
