Mandibular compound odontoma in a young Border collie

Abstract

A four-month-old, female Border collie was presented with a firm swelling of the left mandibular body. The most important differential diagnosis for this type of lesion in a young dog consists of a dentigerous cyst, a papillary squamous cell carcinoma or an odontoma. Intra-oral radiographs were taken and a biopsy was performed to reach a diagnosis. Histopathologic examination revealed a compound ondontoma and the dog was surgically treated. Follow-up showed uneventful healing of the wound and no signs of recurrence were visible on the three-month postoperative radiographs.
