Lymphangiosarcoma in a dog presenting with massive head and neck swelling.
A three-year-old, neutered male Chesapeake Bay retriever was presented for acute onset of severe, progressive swelling of the head, neck, and cranial trunk. Diffuse lymphangiosarcoma involving the superficial and deep dermis and subcutaneous tissue was observed on skin biopsies. Lymphangiosarcoma is a rarely reported tumor of the lymphatic system in dogs and cats. The importance of obtaining skin biopsies in animals with acute edema of unknown etiology is emphasized. Additionally, neoplasia should be considered as a potential diagnosis in a dog with an acute onset of edema.
