Johannes, C. M., C. J. Henry, et al. (2007). "Hemangiosarcoma in cats: 53 cases (1992-2002)." J Am Vet Med Assoc 231(12): 1851-6.

Hemangiosarcoma is a cancer arising from blood vessels and is considered rare in cats. Traditionally, feline hemangiosarcoma is classified as either dermal or visceral, with no distinction between cutaneous and subcutaneous dermal tumors. The purpose of this study was to characterize feline hemangiosarcoma and determine the signalment, clinical signs, biological behavior, treatment outcomes, and prognostic indicators associated with this type of tumor. In a retrospective case series, data from 53 cats with hemangiosarcoma was evaluated. Cutaneous and subcutaneous locations were more common than abdominal and thoracic locations. In 47 of the cats, surgery was the primary treatment. Tumor-free surgical margins were associated with longer survival times and were more likely to be obtained in cutaneous than subcutaneous tumors. Local recurrence was experienced in 6 of the 12 cats with subcutaneous tumors for which follow-up was available. Metastic disease was experienced by several cats. Of the 21 known deaths or euthanasias, 18 were directly related to the tumor. Subcutaneous hemangiosarcoma was more aggressive than the cutaneous form, and it was more likely to recur locally and result in death or euthanasia. Visceral hemangiosarcoma is associated with a grave prognosis.
