Abstract

The multinodular bone tumor is a slow-growing, locally invasive malignant tumor capable of metastasizing. Its occurrence is greater in the flat bones of the skull and hard palate. The clinical signs depend on the location of tumor and are generally related to compression of adjacent structures. This report describes the follow-up of a case of multinodular bone tumor in a currently thirteen-year-old dog, Yorkshire Terrier breed, which was initially treated with neoformation in a region overlapping the topography of the left zygomatic arch and the caudal portion of the left mandibular branch. After performing a skull radiographic evaluation, computed tomography and laboratory investigation, surgical removal and histopathological examination were performed, which confirmed the suspicion of a multinodular bone tumor. Two years after surgery, pulmonary metastasis was found on the left side of the lung. At the time of this publication, the animal is in good general condition and without respiratory symptoms, despite progressive metastatic growth.
