cases. 5 , 11 , 12 Hemangiosarcoma (HSA) is the most common splenic tumor reported in dogs, but it appears to be less common in cats with a reported prevalence of 2% to 21%. 4 , 10 Nevertheless, it accounts for 60% of all neoplasms of cats presenting
Hemangiosarcomas, malignant neoplasms arising from the vascular endothelium, are rare in cats and account for < 1.5% to 2% of nonhematopoietic neoplasms. 1,2 Feline hemangiosarcoma is commonly classified as dermal or visceral, with no distinction
plasma concentrations of cTnI measured by use of that kit is from < 0.03 to 0.07 ng/mL, with the upper tolerance limit (ie, 0.07 ng/mL) at the 90th percentile with 95% confidence. 11 In dogs, hemangiosarcoma most commonly involves the spleen, right
9 was designated as grade 2, and a total score of 10 to 12 was designated as grade 3. For dog 1, histologic assessment revealed a completely excised (< 0.2-mm-wide margins) grade 2 nodal hemangiosarcoma; lymph node architecture was evident in
Hemangiosarcoma is a malignant neoplasm of vascular endothelial origin. It is reported in approximately 0.3% to 2% of recorded necropsies and represents approximately 5% of all nonskin primary malignant neoplasms in dogs. 1,2 Most dogs with
Hemangiosarcoma is a common, highly aggressive malignant tumor of endothelial origin in dogs. 1 Dogs with hemangiosarcoma often have concurrent hemostatic abnormalities, particularly DIC. 2,3 In 1 study, 2 12 of 24 (50%) dogs with
H emangiosarcoma is a rapidly growing, highly invasive cancer arising from the lining of blood vessels of any tissue. 1 More than half of all dogs with hemangiosarcoma primary tumors arise within the spleen. 2 – 4 Because of its aggressive
Hemangiosarcoma is a malignant neoplasm of vascular endothelial cells and, in most anatomic locations, is associated with an aggressive biological behavior and poor prognosis. This type of neoplasm can arise in any tissue; however, in dogs, it is
Hemangiosarcoma is a highly malignant neoplasm of vascular endothelial origin that occurs more commonly in dogs than any other species. 1,2 The spleen is the most common primary site, accounting for 35% to 62% of all primary hemangiosarcomas. 3
Hemangiosarcoma is a malignant tumor of endothelial cells that commonly arises from the spleen, heart, liver, and subcutis in dogs, accounting for 7% of all canine malignant tumors. 1–4 Such tumors are extremely aggressive owing to their high
