“…Neoplastic lesions associated with unerupted teeth have previously been described in 16 dogs: 13 odontomas (7 compound odontomas, 1 ameloblastic odontoma, 1 ameloblastic fibro-odontoma, and 4 non-specified odontomas), 1 squamous papilloma, 1 peripheral odontogenic fibroma, and 1 squamous cell carcinoma (14, 26, 31, 32, 38, 39, 44, 47, 52, 56, 59, 86). Only in six out of 16 cases (37.5%) a cystic component was also described (32, 39, 59, 86).…”

Lack of dental eruption may be accompanied by development of dentigerous cysts and has also been rarely associated with neoplasia. However, little information is available on prevalence of unerupted teeth and associated lesions in dogs and cats. The main objective of this study was to describe the epidemiologic data of canine and feline dental patients with unerupted teeth, and assess the prevalence of associated dentigerous cysts and tumors. Secondary aims included the evaluation of possible factors implicated in cystic development, and description of the histological features of dentigerous cysts. Medical and dental records, intraoral photographs, intraoral radiographs of client-owned dogs and cats with clinically missing teeth examined between 2001 and March 2018 were reviewed. Collected data included signalment, reason for presentation, number, type, depth of inclusion and angulation of unerupted teeth, presence of cystic lesions or tumors, abnormalities affecting involved teeth, histopathological findings, performed treatment and outcome. Seventy-three animals (69 dogs and 4 cats) with 113 unerupted teeth were included. The most frequent unerupted tooth in dogs was the first premolar teeth (78%), followed by the canine and third molar teeth. Dentigerous cysts were diagnosed associated with 48 (44.4%) teeth in dogs and one out of five unerupted teeth in cats. The affected teeth in dogs were predominantly in horizontal inclination (40%) and in soft tissue inclusion (77%). Brachycephalic canine breeds were overrepresented. The only unerupted tooth in boxer dogs was the first premolar tooth (32 teeth). Ninety percentage of boxers with unerupted teeth developed associated lesions (25 dentigerous cysts and one tumor). Two ameloblastomas (one in a dog and one in a cat) and one osteosarcoma (in a dog) were diagnosed in association with three unerupted teeth. Histology was essential in diagnosing two odontogenic cysts not evident on radiographs. In all cases that were followed-up, treatment (i.e., extraction, extraction and surgical curettage, or operculectomy) appeared successful. Untreated dentigerous cysts showed progression at re-examination. None of the unerupted teeth without evidence of cyst at the time of diagnosis showed incipient cystic development. None of the evaluated factors were associated with lack of eruption and/or development of associated lesions.

A 35-month-old female German shepherd weighing 33.2 kg was referred to our department with a 10-month history of sneezing and left nasal swelling. On clinical examination, the dog showed deformity of the left nasal plane in the absence of any cutaneous lesions or nasal discharge, and presented with nasal snoring noises during both the inspiratory and expiratory phases. The patency of nasal cavities was evaluated using the cotton swab test, and was found to be preserved only on the right side. Endoscopic, radiographic and computed tomographic examination revealed an osteoproductive lesion that distorted the nasal, maxillar and frontal bones, completely occupying the left nasal cavity and frontal sinuses, resulting in destruction of the nasal septum and invasion of the contralateral nasal cavity. Five bioptic samples of the mass were collected from the cutaneous surface using a 9G Jamshidi bone marrow bioptic instrument. Histologically, the lesion consisted of a non-encapsulated, multilobulated mass composed of dense coalescing trabeculae of well-differentiated bone, which was lined by osteogenic cells. The morphology was suggestive of nasal osteoma. Due to the large size of the mass, evidenced by computed tomography, chronic systemic nonsteroidal anti-inflammatory treatment with carprofen was proposed instead of surgery. The description of this case is useful for veterinarians, who should consider osteoma as a possible differential diagnosis for nasal tumours.

“…23 Even with benign neoplasia such as osteomas, recurrence at the surgical site has been reported. 24 For that reason, histologically clear bone margins should be attempted with an excisional craniectomy. A publication recommended that bone margins of 1-2 cm should be the goal of excision.…”

A 3‐year‐old spayed female German Shepherd dog was presented for investigation and treatment of a firm slow growing mass over the right surface of the skull. Computed tomography (CT) of the head revealed a proliferative, rounded and well‐defined compact bone mass expanding extracranially. A right rostrotentorial craniectomy was performed with ‘en bloc’ mass resection. To achieve clear margins, the excision of the outer table of the frontal bone, with subsequent opening of the right frontal sinus, was necessary. To provide an appropriate sealing between the cranial cavity and the nasal cavity, thereby preventing future complications, a cemented partial obliteration and reconstruction of the right frontal sinus was performed. The dog recovered uneventfully. Histopathological analysis confirmed complete resection with clear margins and the final diagnosis of an osteoma. The dog was progressing with no clinical signs 8 months after the surgery.
