Plain-English summary
A group of older cats, mostly domestic shorthairs, were found to have unusual growths in their neck lymph nodes, which were diagnosed as a type of cancer called hemangiosarcoma. These cats showed symptoms of swollen lymph nodes, and after biopsies were performed, it was determined that some had benign vascular growths while others had malignant tumors. Unfortunately, six of the cats were euthanized due to their illness, while others survived anywhere from less than a month to over two years after diagnosis. This research highlights the importance of recognizing these types of growths in cats to improve treatment options.

Abstract
A novel form of primary feline hemangiosarcoma and additional cases of plexiform vascularization in the cervical lymph nodes are reported. Sixteen cases of feline lymphadenopathy attributed to abnormal vascular proliferation were identified and evaluated. Most of these lesions were diagnosed histologically as hemangiosarcoma. However, lesions of plexiform vascularization, with and without areas of putative malignant transformation, were also identified. Mean age of the cats was 11 years (range, 3-16 years) with most being domestic shorthair and medium hair (13). Two domestic long hair and 1 Maine Coon were identified. Excisional nodal biopsy was performed in 15 cases and incisional biopsy in 1 case. Six cats were euthanized due to their disease. Survival times ranged from ≤ 1 month to ≥ 30 months. We provide a new clinical differential for cervical lymphadenopathy in cats that is not widely recognized. Proper identification of primary nodal vascular lesions in cats will enable further characterization of clinical features and biologic behavior to determine specific therapy.
