title: Trisomy 2 in three cases of canine haemangiopericytoma.
abstract: Two female (12 and 14 years old) and one male dog (10 years old) developed haemangiopericytomas. Three copies of chromosome 2 were present in the tumours of all three dogs. Additional alterations were an interstitially deleted chromosome 1, centric fusions 3/34 and 8/15, isochromosome 32 and two unidentified marker chromosomes (M1, M2) in one bitch. In the other bitch, the additional alterations were trisomy 37, centric fusions 8/38 and 30/31, and a derivative chromosome 13 (der13). In the male dog, tandem fusion 2/19 was present in addition to two structurally normal chromosomes 2.
