Other Tumor Types Flashcards
Cutaneous Hemangiosarcoma
UV light induced
Inguinal and epidermal (doesn’t penetrate dermis)
Who is most likely to get cutaneous Hemangiosarcoma?
Lightly-haired glabrous skin
Dalmatians, pits, boxers, beagles, whippets
What is the difference in biologic behavior for cutaneous and visceral hemgiosarcoms in dogs?
??
Where is primary visceral HSA mostly found?
Spleen
Liver, right atrium and skin
Anywhere there are Bvs
Most common cardiac tumor
Presentation of visceral HSA
RHF- ascites
Weakness, lethargy, collapse, anemia with pale mm, waxing and waning
Differential dx of splenic masses
Hematoma
Hyperplasia
2/3 malignant and 2/3 HSA
How do you dx Hemangiosarcoma
Histopathology*
Cytology (+ if malignant cells)
Imaging (hypoechic, cavitary)
Clin path changes with Hemangiosarcoma
Anemia: regen if old bleed, non with acute bleeding
Thrombocytopenia
DIC (Exposure of endothelium)
Schistocytes
EKG changes with Hemangiosarcoma
Electrical alternans
Small complexes
What predisposes to injection site carcinoma?
Multiple Ags in the same Vx
Killed Vx
Adjuvanted vx
Which Vx should you use to avoid ISS
Monovalent, non-adjuvated, only necessary Vx, admin SQ not IM
What is the surgical recommendation to get complete margins in ISS?
Avoid interscapular space
Distal limb (allow for amputation)
Tail (more distal)
Sx for ISS
GP MTR= 2-3m
Boarded surgeon= 14m
Amputation
MST= 2y
Recurrence rate after sx for ISS
40-70% with MTR 6m despite clean margins
Signalment of transitional cell carcinoma of the bladder
Older dogs
Females predisposed
Scotties, WHWT, wire-haired fox terrier, shelties, beagles
