Osteopatia hipertrófica paraneoplásica por condrossarcoma pulmonar em cão: relato de caso

Abstract

Objectives: Hypertrophic osteopathy (OH) is a secondary disease characterized by periosteal proliferation. The paraneoplastic presentation of OH is associated with primary or metastatic lung tumors, such as chondrosarcoma. Clinical manifestations include pain, limb edema, and claudication. Diagnossis is made through radiographic examination, allowing visualization of the periosteal proliferation. Intevention for OH involves ablation of the neoplasm and vagotomy. Methodology: A male, mixed-breed dog was presented with bilateral edema of the thoracic limbs, pain, and lameness, with a history of chondrosarcoma 3 years prior. Radiographic were requested, identifying palisading periosteal proliferation in the diaphysis of the phalanges to the humerus, also detecting various pulmonary nodules. Prednisolone 20mg was prescribed for 24 days, resulting is a reduction of edema, pain, and lameness in the limbs. The findings were consistent with paraneoplastic OH, decribed as the main primary cause. Remission of chondrosarcoma 3 years after limb amputation without the aid of adjacent protocols was 893 days. Discussion: The findings were consistent with paraneoplastic OH, associated with lung neoplasia, described the main primary cause. Remission of chondrosarcoma 3 years after limb amputation without the aid of adjacente protocols was 893 days. Conclusion: Hypertrophic osteopathy, is caused by several factors, the main one being lung neoplasia. Its etiology is note clear, so further studies are needed.
