摘要
BackgroundMandibular masses caused by inflammatory processes due to bacterial infections, most common with Actinomyces bovis, are well known in herbivors. This case represents a rare differential diagnosis to common inflammatory processes which cannot be distinguished from neoplasia without detailed histopathological examination.Case presentationA large unilateral mandibular mass of a free-ranging female adult red deer (Cervus elaphus elaphus) was submitted for pathological examination. The animal had been shot due to its poor body condition. Grossly, the mandibular mass showed gingival ulceration and necrosis. Histologically, irregular strands and islands of odontogenic epithelial cells and a matrix of dentin and osteoid-like material were found, leading to the diagnosis of an odontogenic tumor. Considering the animal’s age the tumor was classified as odontoameloblastoma with secondary chronic purulent osteomyelitis.ConclusionsOdontogenic tumors are rare in domestic and wildlife species and so far have not been reported in red deer. In addition to the more common inflammatory processes of the mandibula and other neoplastic diseases of the oral cavity, odontogenic tumors represent a rare differential diagnosis that must be kept in mind especially when masked by inflammatory lesions.

背景技术由细菌感染引起的炎性过程引起的前庭肿块，最常见于牛放线菌，在除草剂中是众所周知的。该病例代表了对常见炎症过程的罕见鉴别诊断，如果不进行详细的组织病理学检查，则无法与肿瘤形成区分开。病例介绍提交了一个大的单侧下颌块游离雌性成年马鹿（Cervus elaphus elaphus）进行病理检查。该动物由于身体状况不佳而被枪杀。大体上，下颌肿块显示出牙龈溃疡和坏死。在组织学上，发现牙源性上皮细胞的不规则链和岛以及牙本质和类骨质样物质的基质，从而导致了牙源性肿瘤的诊断。考虑到动物的年龄，该肿瘤被分类为患有继发性慢性化脓性骨髓炎的牙釉质母细胞瘤。除了下颌和口腔其他赘生性疾病的较常见炎症过程外，牙源性肿瘤还代表一种罕见的鉴别诊断，尤其是在被炎症性病变掩盖时，必须牢记。
