Interpretive Summary: Technical Abstract: Depending on whether the etiologic agent is known, neoplastic diseases of poultry are divided into two main categories: a) virus-induced neoplastic diseases, and b) neoplastic diseases of unknown etiology. Neoplastic diseases cause economic losses from tumor mortality as well as poor performance. Virus-induced neoplastic diseases of poultry are caused by either a herpesvirus (Marek’s disease) or by a retrovirus (leukosis/sarcoma, reticuloendotheliosis and lymphoproliferative disease of turkeys). Neoplastic diseases of unknown etiology include a wide variety of benign and malignant neoplasms derived from muscle, epithelial, and nerve tissues; serous membranes; and pigmented cells. The most common neoplasm of unknown etiology encountered in commercial chickens is dermal squamous cell carcinoma (avian keratoacanthoma), a skin condition most commonly found in broiler chickens. This review is primarily focused on virus-induced neoplastic diseases of poultry, namely Marek’s disease, avian leukosis and reticuloendotheliosis |
