Splenic hemangiosarcoma and concurrent ossifying gastric adenocarcinoma in a dog

An eight-year-old, spayed female, mixed Airedale terrier was presented for chronic vomiting and weight loss. Although emaciated, the dog had a pendulous abdomen with a palpable, left-sided, cranial abdominal mass. Diagnostic imaging confirmed a mass effect associated with both the spleen and stomach; it was unclear whether one mass or two was present. Necropsy confirmed the presence of two unrelated malignant abdominal neoplasms: a splenic hemangiosarcoma and an ossifying gastric adenocarcinoma.
