Acanthomatous epulis is a malignant form of gingival tumor. This is a case of epulis affecting a four-year old, intact, female Maltese dog raised as indoor pet in Iksan city. Clinical examination showed an enlarged palpable mass along the rostral maxillary gingiva. Section of the excised mass showed epithelial overgrowth and expansion from the basal portions through the tissue stroma. Post-surgical radio-graph showed displacement of the first and second maxillary incisors. Histochemical staining showed strongly positive reaction to epithelial marker cytokeratin and moderately positive reaction to connective tissue marker vimentin. This case was diagnosed as a form of maxillary gingival acanthomatous epulis. Routine clinical oral examination is suggested.

A 5-year-old male Chihuahua with oral discomfort due to the presence of a maxillary acanthomatous epulis was referred to the acupuncture service at the Veterinary Medical Center of the University of Florida. For the patient, acupuncture treatments were performed for 11 sessions, at 1 month intervals with Chinese herbal medicine. The acupuncture points and Chinese herbal medicine used were selected based on TCM principles. The selected acupoints were Zusanli(ST36), Fenglong(ST40), Gongsun(SP4), Sanyinjiao(SP6), Pishu(BL20), Weishu(BL21), Taichang(LIV3), and Baihui(GV20). In addition, the Chinese herbal formulas Nei Xiao Wan and Si Jun Zi Tang were chosen. After one year of acupuncture and administration of Chinese herbal medicine, the acanthomatous epulis was remarkably decreased in size. It is considered that the use of acupuncture and Chinese herbal medicine would be useful treatments of canine acanthomatous epulis.

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.

The congenital epulis of newborn is a rare benign tumor that occurs on the gingiva of the anterior alveolar ridge of the jaws, also known as a congenital granular cell tumor. Females are affected 8 - 10 times more often than males. The typical location is the alveolar ridge of the maxilla near the canine but the mandibular region can also be involved. The lesion may be sessile or pedunculated with red or normal color. The size of tumor varies from several millimeters to a few centimeters in diameter. Surgical excision is generally indicated and no recurrences have been noticed. Spontaneous regression is rare. It is histologically similar to the granular cell tumor, although pseudoepitheliomatous hyperplasia does not occur in the former lesion. Thus sheets of large, closely packed cells showing fine, granular, eosinophilic cytoplasm comprise the tumor mass. This is a case report of congenital epulis in the fetus. The lesion was detected in ultrasonogram, its size is 3cm in diameter. The infant showed nursing disturbance and respiratory obstruction after birth, so the tumor was surgically excised under local anesthesia.

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)

Congenital epulis (CE) is an extremely rare benign tumor of the gingiva that is found on the alveolar ridge of newborns, and the main treatment option is simple excision. Postoperative prognosis is very good, and spontaneous regression may occur despite incomplete excision. This report presented a rare case of CE and its healing process after surgery under local anesthesia. The treatment plan was decided upon through consultation between a medical team and the patient's family, with surgical excision for the main lesion, which benefitted from surgery, and follow-up for a very small-sized lesion, which was thought to be appropriate for a newborn. No recurrence was found after its removal, and favorable healing was observed.

A 4-month-old female thoroughbred foal was presented with large mass on mandibular gingiva. The enlarged mass was firm and yellowish pink in color, and occupied the whole mandibular arcade. The filly could not close her mouth with her lips. Radiographs showed radioopaque mass under the mandible. The mass was surgically excised from mandible. Histopathologically, gingival mass was characterized by hyperplastic gingival epithelium, well vascularized collagenous stroma and large area of bony tissues. Based on the gross and histopathologic findings, this case was diagnosed as ossifying epulis in the mandibular gingiva. This is the first report of ossifying epulis in a thoroughbred horse in Korea.

Purpose: The congenital epulis is a rare, benign tumor. It can protrude out of the newborn's mouth to prevent normal closure of the mouth and it can interfere with respiration or feeding. Methods: An 11-day old female neonate presented with a $1.5\;{\times}\;1.5\;{\times}\;2.3cm$ sized mass in the gingival and anterior alveolar ridge of the mandible. We performed a simple excision. Results: In our case, histologically, there was no pseudoepitheliomatous hyperplasia. The staining for S-100 protein, and actin was negative. After 8 months, the patient had normal teeth eruption and no recurrence of the tumor. Conclusion: With early detection and appropriate treatment, we were able to help the baby avoid developing any dyspnea. Nursing was possible after the mass had been removed.
