Plain-English summary
An 8-week-old puppy was found to have a growing lump in the groin area, which turned out to be a type of cancer called lymphangiosarcoma. This cancer affected the blood vessels and spread to nearby lymph nodes. Unfortunately, the puppy was later euthanized at 8 months old due to severe joint infections, and the cancer was confirmed to have spread. This case highlights the aggressive nature of lymphangiosarcoma in young dogs and the importance of early detection.

Abstract
Lymphangiosarcoma was diagnosed from biopsy material obtained from an 8-week-old puppy with a progressively enlarging subcutaneous inguinal swelling. Histologically, the tumor was composed of endothelial cells immediately adjacent to large collagen bundles. Tumor cells formed irregular vascular channels which extended along the connective tissue investments of small vessels and nerves of the subcutis and deep dermis. Similar neoplastic tissue extensively infiltrated an inguinal lymph node. Neoplastic cells were immunohistochemically stained for factor 8-related antigen and were weakly positive when compared with several hemangiomas and hemangiosarcomas. Transmission electron microscopy revealed numerous micropinocytotic vesicles and a continuous basal lamina. The puppy was euthanatized at 8 months of age due to severe septic polyarthritis. Lymphangiosarcoma was documented at the site of the original tumor as well as in the axillary lymph node at necropsy.
