Plain-English summary
A Domestic Shorthaired cat was brought in for coughing and severe breathing problems. X-rays showed a large mass in the lungs along with other smaller masses. Unfortunately, the cat was euthanized, and further examination revealed a rare type of lung cancer called pulmonary carcinosarcoma, which is a mix of two different cancer types. This type of tumor is uncommon in pets and had not been previously reported in cats.

Abstract
A Domestic Shorthaired cat was presented with coughing and severe respiratory distress. Thoracic radiographs revealed a lobar mass and numerous additional cavitated intrapulmonary masses. The cat was euthanized and submitted for necropsy. Histological examination of the large mass revealed 2 distinct neoplastic components consisting of bronchial adenocarcinoma admixed with neoplastic areas composed of highly atypical undifferentiated spindle cells (sarcomatous component). Simultaneous expression of vimentin and cytokeratin by a subpopulation of neoplastic epithelial cells and by rare neoplastic spindle cells was identified. On the basis of histology and immunohistochemical results, a diagnosis of primary pulmonary carcinosarcoma with intrapulmonary epithelial metastases was made. Pulmonary carcinosarcoma is a well-known pathological entity in humans. It is a rare tumor in animals and has not been previously reported in cat.
