Probable hypercalcemia of malignancy in a cat with bronchogenic adenocarcinoma

Abstract

An eight-year-old, neutered male, domestic shorthair cat was referred with a four-day history of acute vomiting. Hypercalcemia was identified on serum biochemical testing. Thoracic radiographs showed multiple pulmonary nodular densities. Postmortem and histopathological examination identified the nodules as bronchogenic adenocarcinoma with metastases to the tracheobronchial lymph nodes, diaphragm, and parietal pleura. To the authors' knowledge, this is the first reported case of hypercalcemia of malignancy associated with bronchogenic adenocarcinoma in a cat.
