Haemangiosarcoma with a Metastasis of a Malignant Mixed Mammary Gland Tumour in a Dog.

Summary An 11-year-old dog with a history of weight loss, anorexia, anaemia, epistaxis and a nodule in the mammary gland showed multifocal lung masses during radiography. At necropsy as well as in the histological examination two different tumours were identified in several organs including the right heart auricle. By immunohistochemistry, using a double-staining DAKO® kit (DAKO Diagnostics, Zug, Switzerland), it was possible to identify the two components as haemangiosarcoma and metastasizing malignant mixed mammary gland tumour.
