Hemangiosarcoma
Hemangiosarcoma is a malignant cancer of blood vessel lining cells (endothelium). It primarily affects dogs, most commonly in the spleen, heart, and skin. It is aggressive and often diagnosed when internal bleeding occurs.
Key Facts
- Most common in dogs; rare in cats
- Predisposed breeds: German Shepherd, Golden Retriever, Labrador
- Three forms: dermal (skin), hypodermal (under skin), visceral (internal organs)
- Visceral form often presents as sudden collapse from internal bleeding (splenic rupture)
- Diagnosis often incidental during emergency surgery for internal hemorrhage
- Treatment: surgery + chemotherapy (doxorubicin-based protocols)
- Median survival with surgery alone: 1-3 months; with chemo: 5-7 months
- Dermal form has better prognosis than visceral
- Species: dogs (primarily); cats (rare)
