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. A biopsy is a surgical removal of a portion of the tumor. Both are odontogenic tumors of limited growth potential that do not recur if adequately excised; both occur in middle and late adulthood of the species concerned. odontogenic benign neoplasms (NOBN) and odontogenic benign neoplasms (OBN) in 130 dogs with oral tumors.

Amyloid-producing odontogenic tumors (APOT) have been described in dogs, cats and a Bengali tiger. FNA involves taking a small needle with a syringe and suctioning a sample of cells directly from the tumor and placing them on a microscope slide. POF appears to originate from the periodontal ligament, arising in the soft tissue adjacent to a tooth, and is covered by epithelium. Some of the gingival enlargements previously described as fibromatous and ossifying epulides were renamed as peripheral odontogenic fibromas (POFs). 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.

In some cases partial mandibulectomy is required to completely excise the mass and eliminate the trauma. Epulis, ossifying epulis, fibromatous epulis, and fibroosseous epulis are all terms that have been used in the past. Although rare, Peripheral Odontogenic Fibroma’s have been known to show variable amounts of bone and bone matrix. A biopsy is required in order to definitively diagnose Peripheral Odontogenic Fibromas (Epulis). Staging is recommended for oral tumors, and CT imaging is advised for planning treatment, whether surgical or radiation. The excision and extraction site are typically closed with 4-0 monocryl in a large dog or 5-0 monocryl in a small dog. (11) There are no reports of metastasis of APOT in the literature.

Peripheral Odontogenic Fibroma (POF): This is a type of tumor that was previously referred to as an “epulis,” or a growth associated with dental structures.As pathologists delved into oral pathology more thoroughly in recent years, they realized that “epulis” was an over-simplified definition, and as such, it went out of favor. Dogs that undergo excision of Peripheral Odontogentic Fibromas do well post-operatively with minimal to no change in appearance as well as quality of life greatly heightened. POFs are slow growing benign neoplasms that are common in dogs, and less common in cats. This can cause a significant swelling in the region and also obvious pain. Any remaining tooth socket (alveolus) is contoured with a diamond bur to remove any remaining periodontal ligament fibers. One, the common fibromatous epulis.

Peripheral odontogenic fibroma (previously called ossifying epulides) is similar in appearance to a fibromatous epulis as it also has a pink smooth surface, but it has an osteoid matrix; it’s made up of early-stage bone cells known as osteoblasts. Treatment involves surgical removal of the tumorous tissue. Many of the tumors previously described as fibromatous and ossifying epulides have been reclassified as peripheral odontogenic fibroma (POF). Like humans, benign and malignant tumors occur in dogs’ mouths. Diagnosis may be performed via fine needle aspiration or biopsy. Spread to mandibular lymph nodes does occur.
