Hypertrophic Osteopathy Associated with Lung Adenocarcinoma in a Cat: An Overview

Abstract Hypertrophic osteopathy (HO) is a pathological condition characterized by progressive, bilateral and symmetrical periosteal bone hyperostosis. considered secondary disease that occurs as consequence of many chronic processes, which are primarily localized in the thoracic cavity (intrathoracic lesions), less result changes abdominal (extrathoracic lesions). We describe case 3.5-year-old female unneutered short-haired cat with history weight loss, decreased appetite, dyspnea, wet cough. During native X-ray examination cavity, clearly limited homogeneous radiopaque shadow covered entire was found, well periostitis front limbs, mainly on humeri, radii ulnae. After euthanizing cat, control necropsy body performed. The revealed soft-tissue proliferation measuring 13 x 5 4 cm weighing 228 g, pronounced ossified periostosis long bones, while histopathological findings adenocarcinoma lung metastasis to mediastinal lymph nodes. outcome hypertrophic mostly depends primary cause. If initial lesion had been identified removed time, would have also receded spontaneously. tool determining diagnosis. Considering determination this an indicator ongoing severe disease, especially its early diagnosis lead prolongation animal's life.
