A 12-year-old spayed female American short-haired cat presented with a palatal gingival
mass located between the right maxillary third incisor and the canine teeth. The mass was
dark red and had a narrow attachment to the gingival margin of the canine tooth. The mass
was completely removed by marginal excision and the histopathological diagnosis was a
capillary hemangioma. The mass did not relapse until 1 year later; however, the tooth was
extracted because of cervical resorption of the right maxillary canine immediately
adjacent to the mass resection site. This report presents a rare case of the gingival
hemangioma in a cat and the possibility of a causal relationship between the occurrence of
external cervical tooth resorption and hemangioma resection.
