Hemoabdomen secundario a hemangiosarcoma esplénico en canino.

Abstract

Hemangiosarcoma is a malignant neoplasm that originates from pluripotential bone marrow cells circulating in the blood. It is highly metastatic and originates from the vascular endothelium and is generally located in the spleen, liver, heart (right atrium) and with lesser incidence in other organs such as bone, urinary bladder, kidney, lung, skin, oral cavity, muscle and peritoneum. The most common alterations are anemia, abdominal effusion and periodic weakness or collapse due to peripheral hypoperfusion. An 8-year-old white Siberian Husky male dog, neutered, weighing 29.5 kg, reported anorexia, lethargy and abdominal distension of one week of evolution. The general clinical examination revealed pale mucous membranes, pendulous and tender abdomen. Paraclinical findings were normocytic normochromic anemia, thrombocytopenia, lymphocytosis. Abdominal ultrasound showed free fluid in the peritoneal cavity and a mass with focal areas of echogenicity in the spleen. The patient was admitted for exploratory laparotomy where a splenic hemangiosarcoma was confirmed.
