Abstract
This paper describes the clinical features and management of adenosquamous carcinomas developing in the larynx and orbit of two dogs. Case 1 showed signs of dysphonia and dyspnea caused by a mass within the vocal cord, and case 2 presented with clinical signs of the hyperlemia of the right-sided palpebral conjunctiva due to a mass occupying the right orbit. In both cases, histopathological examinations revealed that both neoplastic masses contained the elements of adenocarcinoma and squamous cell carcinoma, and these were diagnosed as adenosquamous carcinoma, respectively. Case 1 survives with a reduction in tumor size through chemotherapy, despite a recurrence. Case 2 continues to follow a favorable course without recurrence or metastasis.
