Abstract
An approximately 30-year-old intact female Asiatic black bear (Ursus thibetanus) was presented for annual examination and a history of ptyalism. A large 9.5 cm × 5 cm × 5 cm, firm, round mass was identified attached to the hard palate on physical examination. A computed tomography scan was performed, and the heterogeneous, mineral-attenuating mass was seen arising from the right aspect of the palatine bone and extending rostrally to the level of the last maxillary molars, caudally into the oropharynx, and dorsally into the nasal choana. Surgical debulking was performed to remove the portion of the mass within the oral cavity. Histopathologic analysis was consistent with a keratinizing ameloblastoma. Nine months postoperatively, the patient was asymptomatic for the tumor. The patient was euthanized 23-months postoperatively, and severe diffuse pustular dermatitis, growth of the ameloblastoma on the hard palate, and various degenerative and aging changes were noted on necropsy at that time. This is the first report of an ameloblastoma in a member of the Ursidae family.

Abstract
The documented increase in the occurrence of dental diseases in captive big cats over the past decades has necessitated the need to target dental medical research accordingly. The aim of this study was the systematic evaluation of dental and oral pathologies of lions and tigers which included intraoral dental radiography. Thirty-six animals of both sexes, ranging in age from nine months to 18 years, predominantly in circus husbandry, served as the basis of the present study, and their dental health status was investigated. The preliminary report and history, adspection of the awake animal, and examination under anesthesia provided important information. Eight animals were specifically presented for oral examination because of known dental disease. The remaining 28 animals were anesthetized for other medically necessary procedures, and each animal's oral and dental health status was also evaluated while under anesthesia. In the 28 animals that underwent routine oral cavity examination, pathological changes that had not previously been noticed were found in two-thirds of the animals (19/28). One-quarter of all the animals (9/36) had no abnormal oral cavity findings. Dentoalveolar trauma such as tooth fractures and abrasion (24/36) were diagnosed most frequently. The results highlight the importance of regular oral examinations in big cats. Furthermore, the results suggest that there is a relationship between husbandry conditions and the incidence of dentoalveolar trauma in captive big cats.

Abstract
OBJECTIVES This study aimed to characterize the clinical, radiographic and histopathologic features of early-onset gingivitis (EOG) and periodontitis in cats. METHODS The medical records database was searched for cats diagnosed with histologically confirmed EOG or periodontitis from 1997 to 2022. Information such as medical history, lifestyle factors, clinical presentation, radiographic and histopathologic features were included for 27 client-owned cats. Response to treatment and long-term follow-up was also recorded. RESULTS Moderate-to-severe periodontal disease was radiographically confirmed in 78% (21/27) of cats with moderate-to-severe EOG, compared with the evidence of periodontal disease noted in 30% (8/27) of cases during awake oral examination. Horizontal bone loss, along with missing teeth, were the predominant radiographic features noted in 89% (24/27) of cases. The predominant histopathologic feature was moderate-to-severe, erosive-to-ulcerative, neutrophilic and lymphoplasmacytic inflammation with varying degrees of epithelial and stromal hyperplasia. Two cats developed feline chronic gingivostomatitis (FCGS)-like lesions, and seven cats exhibited worsening of aggressive periodontitis (AP). Lack of improvement in the severity of gingivitis or clinical signs evident at the first follow-up appointment was significantly associated with progression of disease (P = 0.004). CONCLUSIONS AND RELEVANCE The results of this study demonstrate the importance of oral evaluations in cats as early as 6 months of age. For cats exhibiting substantial gingivitis, an anesthetized evaluation, periodontal treatment and long-term monitoring are recommended. Given the high frequency of moderate-to-severe periodontitis encountered in these cats, clients should be informed about the potential need for tooth extractions. EOG may progress to AP. Finally, this study suggests that there could be a link between EOG and FCGS; however, further studies are needed to better characterize this condition and establish any potential link between the two entities.

Abstract
CASE SERIES SUMMARY Feline maxillary sarcomas are aggressive spindle cell neoplasms that occur within the maxilla, palate and upper lip of cats. This diagnosis includes fibrosarcoma and sarcomas with indeterminate histomorphology, excluding melanocytic tumors and sarcomas that can be differentiated by histomorphology. In this study of feline maxillary sarcomas in 25 cats, the cats' ages ranged from 4 to 16 years (median 12.5). These sarcomas presented as smooth thickenings or mass lesions of the gingiva and palate, often involving both the right and left quadrants of the maxilla. Radiographic bone loss was typically absent to mild at the time of diagnosis. Histologically, feline maxillary sarcomas were composed of spindle cells with varying amounts of fibrous stroma and mild inflammation. Metastasis was not documented for any cat in the study, although clinical staging was limited. Cats were often euthanized because of local recurrence following incomplete tumor excision and local tumor progression. Median survival time from the date of histologic diagnosis was 70 days (n = 12). RELEVANCE AND NOVEL INFORMATION Feline maxillary sarcomas are aggressive neoplasms that may be difficult to differentiate from a benign, reactive process or other types of spindle cell neoplasms. Our findings indicate that feline maxillary sarcoma has distinctive clinical and histopathologic features, and the information provided in this paper will facilitate early and specific diagnosis of this tumor.

Abstract
Development of gingival enlargement and periodontitis is described in a young dwarf mongoose. Repeated treatments resulted in gingival resection and histologic evaluation however gingival enlargement was ultimately responsive to extraction of associated teeth. In cases such as these, surgical extraction of teeth associated with severe recurrent gingival enlargement should be considered to avoid the stress and risk of repeated immobilizations.

Abstract
OBJECTIVES The aim of this study was to analyse the frequency of oral cavity lesions in cats, their anatomical location and histological diagnosis, and the effect of life stage, breed and sex on different diagnoses. METHODS For this purpose, a retrospective study comprising 297 feline oral cavity lesions was performed over a 6-year period between 2010 and 2015. Histopathological records from the DNAtech Pathology Laboratory (Lisbon, Portugal) were analysed. RESULTS The incidence of oral disease was higher in male cats (n = 173; 58.4%), mature adults (ranging from 7 to 10 years old [n = 88; 33.0%]) and in the European Shorthair breed (n = 206; 73.6%). The gingiva was the site where oral lesions were most commonly found, with 128 samples (43.1%). Incisional biopsies were used to obtain the majority of samples (n = 256; 86.2%), while excisional biopsies and punch biopsies were performed in 36 (12.1%) and five (1.7%) cases, respectively. Inflammatory and neoplastic lesions accounted for 187 (63%) and 110 (37%) of the studied cases, respectively. Malignancies were found in >80% of neoplastic cases. Feline chronic gingivostomatitis was the most common histological diagnosis (n = 116; 39.1%), followed by squamous cell carcinoma (n = 49; 16.5%) and eosinophilic granuloma complex (n = 33; 11.1%). CONCLUSIONS AND RELEVANCE The present work, involving a large series of samples of feline oral cavity lesions, from numerous geographically scattered practices and all examined at a reference veterinary pathology laboratory, adds important new understanding of the epidemiology of feline oral disease.

Abstract
Peripheral odontogenic fibroma (POF) is an uncommon finding in the mouth of cats. Few cases have been reported in the literature. 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. Despite the high incidence of recurrence reported in the literature, recheck examinations up to 11 months postoperatively did not show regrowth of the gingival masses. Thus, marginal excision including removal of underlying bone appears to be a viable treatment option for POF in cats.

Abstract
Objectives There is a distinct subset of lesions arising on the digits of cats, located at or close to the nail-bed epithelium, which are typically composed of proliferative fibroblast-like cells, multinucleate giant cells and areas of osseous metaplasia, but currently there is no published literature detailing the clinical or histological features of these lesions. Methods This study identified 41 such cases from two large commercial diagnostic laboratories and assessed various histological and clinical features; 22 cases had additional follow-up data available. Results All masses in this study were exophytic, variably inflamed, contained large numbers of spindle cells and had areas of capillary formation. The majority also had areas of ulceration, multinucleate giant cells and osseous metaplasia. The mitotic count was variable, but mitoses were confined to the fibroblast-like cells. Male cats appeared predisposed and the second digit was the most commonly affected. Conclusions and relevance These distinctive lesions arising on the digits of cats had potential for local recurrence but metastasis was not reported. Based on these clinical and histological features, the masses in this study appear most similar to giant cell reparative granulomas, and trauma, injury to the nail or nail-bed and nail-bed infections may potentially contribute to their development.

Abstract
Background Neoplastic lesions of the mammary gland, lymph nodes, or oral cavity in African pygmy hedgehogs (Atelerix albiventris) are common in captive animals. Chemotherapy and radiotherapy protocols have not yet been established for the African pygmy hedgehog. Thus, surgical resection is the current treatment of choice in this species. Case presentation A 5-year-old male African pygmy hedgehog showed multiple erythematous, round small tumors located in the oral cavity, on both sides of maxilla. The treatment of choice was surgical resection of tumors using a surgical knife under general anesthesia. Excised neoplastic lesions were diagnosed as peripheral odontogenic fibroma by histopathology. Six months after surgery relapse of tumors in the oral cavity was not observed. Conclusions The treatment adopted in this case report is safe for the patient and provides the best solution for mild proliferative lesions of the oral cavity. To our knowledge this is the first report of surgical resection of oral tumors (peripheral odontogenic fibroma) in the African pygmy hedgehog.

Abstract
Reports of neoplasia in captive reptiles are becoming more frequent; however, there is still scarce knowledge of the occurrence of neoplasia in wild reptiles. A wild black rat snake (Pantherophis alleghaniensis) was presented to the Zoological Medicine service of the University of Georgia's Veterinary Teaching Hospital with a 3 cm in diameter solid mandibular mass that was partially ulcerated. Radiographically, the mass was radiopaque with small bone spicules and partial osteolysis of the adjacent mandible. Histologic examination of the mass revealed a neoplasm composed of cuboidal to polygonal cells arranged in islands, anastomosing cords, and trabeculae of pseudostratified epithelium with a palisading peripheral layer of densely packed columnar cells with cytoplasmic clearing. The neoplastic tissue was separated from the mesenchyme by a prominent band of fine collagen. Neoplastic cells were positive for cytokeratin and negative for smooth muscle actin. Electron microscopy highlighted the presence of tonofilaments and microvilli. These findings led to the diagnosis of ameloblastoma, an odontogenic epithelial tumor known to occur in humans and most veterinary species.

Abstract
Clinical and histologic features of 26 cases of canine peripheral giant cell granuloma (formerly giant cell epulis) are reported. Two main histologic categories were evident: (1) “classic” peripheral giant cell granuloma, characterized by variable numbers of multinucleated giant cells (MNGCs) admixed with densely cellular mononuclear spindle-shaped cells in variable amounts of collagenous matrix, and (2) the “collision” peripheral giant cell granuloma, with features of both a peripheral giant cell granuloma and a fibromatous epulis of periodontal ligament origin. In the 16 dogs for which the outcome was known, 2 peripheral giant cell granulomas recurred after excision. No age or sex predilection was evident; however, lesions were more common in maxillary than in mandibular gingiva. In contrast to cats, peripheral giant cell granulomas in dogs behave like fibromatous epulides of periodontal ligament origin and seldom recur after excision. Positive staining with TRAP (tartrate-resistant acid phosphatase) of the MNGCs and a fraction of the mononuclear cell population is consistent with osteoclastic origin.

Abstract
OBJECTIVES To determine which types of tumour occur in cats up to the age of 12 months based on biopsies submitted to Idexx Laboratories, Wetherby, UK. METHODS Retrospective review of histopathological diagnoses of tumours in cats up to the age of 12 months from biopsies received between September 1993 and March 2008. RESULTS A total of 4196 submissions from cats 12 months old or younger were identified; 233 biopsies (6%) were neoplastic and fulfilled the search criteria. Tumours were categorised as haematopoietic (n=73, 31%), malignant epithelial (n=44; 19%), malignant mesenchymal (n=38; 16%), benign epithelial (n=37; 16%), benign mesenchymal (n=30, 13%) and miscellaneous (n=11; 5%). The most frequent tumours were lymphoma (n=51; 22%), soft-tissue sarcoma (n=34; 15%), mast cell tumour (n=22; 9%) and squamous cell carcinoma (n=16; 7%). The most common tumour site was the skin and soft tissues (41% of tumours). In all, 164 neoplasms (70%) were malignant or had malignant potential. CLINICAL SIGNIFICANCE These data provide unique epidemiological information on a poorly characterised subgroup of feline cancer patients in the UK.

Abstract
Practical relevance Oral cancers are not the most common tumour in our domestic cats, but the death rate associated with cancer in this location is particularly high. This is largely because the cancer is discovered late in its development and also because of the severe debility it causes when the patient is unable or unwilling to eat and drink. Audience This review of malignant oral tumours (squamous cell carcinoma, oral sarcoma, oral melanoma and salivary adenocarcinoma) and benign oral tumours that may mimic malignant lesions is directed at all veterinarians that see older cats - both for ‘health and wellness’ as well as for more advanced treatment of already diagnosed neoplasia. Patient group As it is almost always older cats that are affected, patients will have a strong bond with their owners. These cats also often have unrelated intercurrent disease that may affect treatment choices, the way treatment is administered, and whether the owner chooses aggressive or palliative therapy. Evidence base While the literature on treatment of oral cancer in dogs is well established, until recently it was less so in cats. As researchers focus on treating cats with curative intent, as well as palliatively and supportively, the material available to guide veterinarians has also increased. This article evaluates the current literature from the author's perspective as an oncologist and a cat owner.
