GINGIVAL VASCULAR HAMARTOMA WITH ASSOCIATED PARANEOPLASTIC HYPERGLYCEMIA IN A KITTEN

A 4-month-old domestic shorthair cat was examined because of a maxilla ry gingival mass that had regrown following excisional biopsy. The kit ten also had a history of persistently high blood glucose concentratio ns, despite 2 weeks of insulin treatment. Radiography revealed maxilla ry alveolar bone lysis and displacement of multiple teeth. Partial max illectomy was performed to remove the mass, which histologically was a gingival vascular hamartoma. Hyperglycemia permanently resolved < 24 hours after mass removal. On the basis of the temporal relationship be tween mass removal and resolution of hyperglycemia, as well as the lac k of evidence of any concurrent disease, hyperglycemia in this cat was considered to be a paraneoplastic syndrome.
