to diagnose melanoma in horses
Surgical resection!, radiation therapy, intratumoral chemotherapeutics, cimetidine,
melanoma vaccination, intratumoral interleukin - Answer-6 treatment options for
melanoma in horses
Sarcoid - Answer-Benign but locally aggressive tumor of horses classified according to
gross appearance (occult, verrucous, nodular, fibroblastic, mixed, malignant) that can
occur at any age following an injury and can be associated with bovine papillomavirus 2
Typical clinical features (associated with injury/non-healing wounds, gross appearance),
PCR for BPV, surgical excision with biopsy - Answer-What diagnostics are used to
diagnose sarcoids in horses
Benign neglect, surgical removal + chemotherapy - Answer-What are the treatment
options for sarcoids in horses
Mesothelioma - Answer-Second most common primary thoracic tumor in horses that
typically affects young horses with nodules that disseminate throughout the pleura and
stimulates effusion; no treatment
95% - Answer-Transitional cell carcinoma makes up ___% of bladder cancer in dogs
Hematuria, dysuria, stranguria, pollakiuria, recurrent UTIs, tenesmus - Answer-What are
6 common presenting complaints associated with potential bladder cancer
UTI, stones, cystitis, coagulopathy, neoplasia - Answer-What are the 5 most common
differentials for a presenting complaint that involves the bladder
Scotties - Answer-Which breed of dog is most predisposed to bladder cancer
Abdominal ultrasound - Answer-Bladder masses are best identified using ____ ____
Trigone - Answer-What is the most common location within the bladder for tumors to
occur
, Voided - Answer-30% of bladder masses can be classified based on a ____ urine
sample (TCC)
Urinalysis/sediment, traumatic catheterization, cystoscopy, biopsy, BRAF test - Answer-
What are 5 ways to determine what type of neoplasm a bladder mass is
Medial iliac, sacral - Answer-What lymph nodes does TCC tend to metastasize to?
Non-trigonal mass provides better prognosis because their urethra is not blocked as
soon so they can urinate (not being able to urinate is why trigonal TCC patients die) -
Answer-Why is the prognosis better for non-trigonal bladder masses compared to
trigonal bladder masses
Chemo (mitoxantrone, vinblastine, chlorambucil), NSAIDs (piroxicam) - Answer-What is
the treatment of choice bladder cancer
1 year, 6 months - Answer-What is the prognosis for TCC with chemo and NSAIDs vs
only NSAIDs
SCC, lymphoma - Answer-What are the most frequent conjunctival neoplasms in horses
Hemangioma/hemangiosarcoma - Answer-Neoplasm that can present in the conjunctiva
of dogs that is suspected to be related to UV exposure that appears as solitary, smooth,
red nodules that can be locally invasive; dx by exam/biopsy; excision typically curative
Histiocytoma, papilloma - Answer-Eyelid tumors in dogs are usually benign and the two
most common types are ____ and ____; spontaneous regression or surgical excision
Preserve vision, limit effect on cosmetic appearance, preserve function of the lids, limit
recurrence - Answer-What are the 4 goals of periocular tumor management
SCC - Answer-Most common type of periocular/ocular tumor in horses, cats, and cattle
Debulk mass, adjunctive cryotherapy or topical chemotherapy - Answer-What is the
treatment for conjunctival SCC
Radiation (strontium 90), CO2 laser - Answer-What is the treatment for SCC of the
limbus or cornea
Sarcoid - Answer-What is the second most common periocular tumor in horses
Surgical excision (needs adjunctive therapy from the start), topical immune stimulants,
immune-therapy, radiation, local chemotherapy, cryotherapy - Answer-What are the
potential treatment options for periocular sarcoids in horses
