Liposarcoma in the Nasal Cavity of a Cow

Abstract

Liposarcomas are rare neoplasms in domestic animals, but have been reported to occur in many species. in humans, liposarcoma is one of the most common malignant mesenchymal tumors. classification of liposarcomas in humans has been well established and categorization by type can be of prognostic value; no such unique classification scheme has been established for liposarcomas in animals. Liposarcoma of the head and neck in humans are uncommon, and are rarely reported in the nasal cavity, sinuses, and nasopharynx. To our knowledge, a liposarcoma has never been reported in the nasal cavity of a domestic animal. In this report we describe a liposarcoma that developed in the nasal cavity of a cow, with local invasion into the oral cavity.
