Data regarding clinicopathologic features of the 3 most common lesions (canine acanthomatous ameloblastoma [CAA], peripheral odontogenic fibroma [POF], and FFH) were summarized. Peripheral odontogenic fibroma (POF). Like humans, benign and malignant tumors occur in dogs’ mouths. Monitor your dogs mouth regularly at home by lifting his lips and inspecting the gum line. Peripheral Odontogenic Fibroma is the preferred name of a mass in the oral cavity of a dog that is derived from the periodontal ligament cells that hold the tooth in the socket.

This can cause a significant swelling in the region and also obvious pain.

Oral Tumors in Dogs - An Overview. An incision is made to ensure all of the Peripheral Odontogenic Fibroma is removed. Peripheral Odontogenic Fibromas are not commonly seen in cats but when present often present as multiple epulides. Benign Masses6 The most common oral growths were originally termed epulids (fibromatous and ossifying)1; now they are identified as peripheral odontogenic fibromas.6 Another benign oral mass is the acnthomatous ameloblastoma, which was originally termed an epulis. One, the common fibromatous epulis, is equivalent to the rare peripheral odontogenic fibroma in human beings. Discontinue the availability of hard bones or toys. Peripheral odontogenic fibroma (formerly known as fibromatous and ossifying epulis) is a benign, often slow-growing tumor that arises from periodontal structures (gums, ligaments, and bone).

Peripheral odontogenic fibroma (POF) Diagnostic imaging in veterinary dental practice. The excision and extraction site are typically closed with 4-0 monocryl in a large dog or 5-0 monocryl in a small dog. Peripheral Odontogenic Fibromas in Dogs. This type of epulis (once known as a fibromatous epulis or an ossifying epulis) is the most common non-cancerous tumor found in dogs. It is not uncommon for the patient to experience blood tinged saliva for the first 24-48 hours. Any remaining tooth socket (alveolus) is contoured with a diamond bur to remove any remaining periodontal ligament fibers. Dogs are very adaptive and will quickly learn their new ways of eating, drinking, grooming, and playing if the mass is large and extensive tissue removal is needed. Recurrence is not expected.

Masses start small but can continue to grow and become large. Can Vet J 37(12):740-741 ↑ Cook JL et al (1998) Infantile desmoid-type fibromatosis in an Akita puppy. Odontogenic tumors occurring on the gingiva (i.e., as epulides) are referred to as peripheral odontogenic tumors. Some of the gingival enlargements previously described as fibromatous and ossifying epulides were renamed as peripheral odontogenic fibromas (POFs). Jerky Dog Treats from China may be Associated with Kidney Issues. "The author of this clinical commentary was A.R. The teeth associated with the mass are extracted and the bone excised. In dogs, most primary bone tumors are sarcomas, especially osteosarcoma; benign tumors of bone are much less common. Peripheral odontogenic fibromas (POF) are the most common benign tumors while oral melanomas, squamous cell carcinomas, and fibrosarcomas are the most prevalent malignant tumors in dogs. Beckman’s Canine and Feline Dentistry seminars include relevant, practical and engaging lectures, interspersed with hands-on experience performing full-mouth extractions in dogs and cats.”, Peripheral Odontogenic Fibroma and Epulis in Dog. Peripheral odontogenic fibromas (POF) are the most common benign tumors while oral melanomas, squamous cell carcinomas, and fibrosarcomas are the most prevalent malignant tumors in dogs. According to the literature, the most common tumors of The present report describes an adolescent, male-castrated domestic shorthair cat with POFs at the rostral upper and lower jaws that were treated via marginal excision including removal of underlying bone. Canine acanthomatous ameloblastoma: Gray-pink papillary to sessile mass in the vicinity of the alveolus (2,8) These tumors are slowly progressive, locally invasive and can recur locally after excision. Acanthomatus ameloblastomas produce destruction of the underlying bone. Wide margins are not needed however no abnormal tissue should be left following excision. Although rare, Peripheral Odontogenic Fibroma’s have been known to show variable amounts of bone and bone matrix. (11) There are no reports of metastasis of APOT in the literature. J Am Anim Hosp Assoc 34(4):291-294 ↑ Boehm B et al (2011) Odontogenic tumours in the dog and cat. These tumors may also affect the nasal cavity. Figure 11B. Ossifying epulis.
