Mammary gland disease Flashcards
How often are mammary neoplasia malignant in dogs and cats
dogs- 50% and up to 50% have metastasized by presentation
cat- 85%
List 6 prognostic indicators of mammary neoplasia
rapid growth
poor delineation
inflammatory changes
ulceration
metastasis to regional LN
tumour size at presentation
Stage the tumour:
Poppy has a 1 cm well-defined clearly marginated firm nodule in R mammary gland 4. There is no difference in size between the L and R inguinal lymph node
T1, NX, MX
Likely Stage 1
Stage this tumour:
Trudy has a 3.5 cm poorly-defined soft ulcerated nodule in L mammary gland 4. The L inguinal lymph node is 2.5 x 1.5 x 0.5 cm
There is lung metastases
T2, N1, M1
Stage 5
How would you treat Masses less than 1cm in diameter and firm on palpation
Lumpectomy
How would you treat
Masses greater than 1cm and those attached to skin or deeper tissue
single mastectomy
If a mammary neoplasia has grown rapidily what shouldn’t you do
lumpectomy
because shows is of an aggressive nature
T/F we treat mammary neoplasia more aggressively in cat compared to dogs
True
Radical mastectomy is recommended
List 6 common conditions of the mammary gland
Galactostasis
Agalactia
Mastitis
Mammary Tumours
Pseudopregnancy
Fibro-epithelial hyperplasia in queens
what is Galactostasis
is milk retention, and there is no systemic illness, even though the glands become engorged, hot, and painful.
what is agalactia
is the absence of milk production in an animal that should be producing milk.
what is mastitis associated with
ascending bacterial infection with E. coli, streps and staphs
Describe how to treat mastitis
Broad spec ABs
hot-packing
fluid therapy
if abscessed- lance, drain and flush
what is fibroepithelial hyperplasia
Significant mammary enlargement caused by local growth hormone production in response to progesterone (like a local acromegaly)
Describe how to treat fibroepithelial hyperplasia
need to remove the progesterone stimulation
needs to be managed quickly
spay
