A short review of canine tumors diagnosed at Department of veterinary pathology, Zagreb, Croatia, during years 2006-2009

Introduction: The significance of monitoring of incidence of animal tumors is indisputable. Taking that in account, we analysed data about canine tumors occurence in Croatia, and presented certain aspects of it. Materials and methods: Data about canine tumors diagnosed at our institution (either submitted from live animal or obtained at necropsy) were retrospectively analysed for years 2006-2009. A WHO Histological Classification of Tumors of Domestic Animals was used at designating diagnosis. Results: There was a total of 1627 tumors, of which 962 (59, 1%) were malignant, and 576 (35, 4%) benign, the rest of 89 (5, 5%) were treated as not specified. Most tumors originated from the skin or subcutis (747, 45, 9%) and mammary gland (352, 21, 6%). Most frequent individual tumor type was mammary tubulopapillary carcinoma (119, 7, 31%), followed by squamous cell carcinoma (89, 5, 47%) and mast cell tumor (81, 4, 98%). Most common tumor types in particular age groups were as follows: 0-1, 99 years and 2-3, 99 years - canine cutaneous histiocytoma (17 cases - 27, 87% and 13 cases – 16, 25%), 4-5, 99 years and 6-7, 99 years – mast cell tumor (16 – 12, 9% and 17 – 8, 09%), 8-9, 99 years, 10-11, 99 years, 12-13, 99 years and 14 years and up - mammary tubulopapillary carcinoma (27 – 8, 65% ; 29 – 8, 36% ; 32 – 11, 98% ; 14 – 8, 75%, respectively). Conclusion: Overall frequencies of dominant tumor types and major tissue of origin show figures comparable to other investigations.
