Abstract

A three-month-old, male German shepherd dog was admitted with a facial mass of two months' duration. Clinical examination showed a round mass, 3 cm in diameter, in the left infraorbital area. The upper last premolar deciduous tooth was not erupted. No other abnormalities were detected. Radiological examination revealed a posterior maxillary mass of mixed opacity. The mass was surgically excised. Histopathological examination demonstrated a connective tissue stroma containing foci of irregular enamel and dentine, resembling rudimentary teeth (denticles), surrounded by new bone formation. Morphology and structure of the denticles were also confirmed by scanning electron microscopy. A compound odontoma was diagnosed. One year after surgery, the dog was free of clinical signs.

摘要

一只三个月大的雄性德国牧羊犬因持续两个月的面部肿块入院。临床检查显示，左侧眶下区域有一个直径3厘米的圆形肿块。上颌最后一颗乳前磨牙未萌出。未发现其他异常。放射学检查显示上颌后部有一个混合性密度的肿块。该肿块通过手术切除。组织病理学检查显示，结缔组织基质中含有不规则釉质和牙本质灶，类似原始牙齿（牙瘤），周围有新骨形成。扫描电子显微镜也证实了牙瘤的形态和结构。诊断为复合性牙瘤。手术后一年，这只狗没有临床症状。
