Epithelial Tissue

Surgical error. Ovarian tissue left behind at OHE/OVE
Pathophysiology of cystic endometrial hyperplasia.
Excess progesterone
Bacteria most responsible for pyometra.
E.Coli
Why is pyometra less common in cats?
Cats are induced ovulators therefore less chance of excess progesterone.
When does metritis occur?
Postpartum (~12 hours - 1week)
The following are a list of etiologies for which reproductive tract infection:
Dystocia
Obstertric manipulation
Retained fetus or placenta
Devitalized uterine tissue
Metritis
This thing is commonly associated with dystocia. It is caused by a rotation of the uterine horn on long axis.
Uterine Torsion- medical emergency
This is a complication of parturition for up to 48 hours following final fetus. More common in cats.
Uterine Prolapse
Most common benign uterine neoplasia in the dog.
Leiomyoma
Feline:
Malignant or Benign Uterine Neoplasia
Malignant and metastatic
What happens in the vagina that is caused by retained embryonic epithelial tissue?
Vestibulovaginal Stenosis
No basis for genetic transmission
Name that v-v stenosis:
“Double Vagina”
Thin band of mucosa
V-v stenosis- SEPTAL
Name that v-v stenosis:
“Imperforate hymen”
Rind shaped
Annular
Name that v-v stenosis:
Narrowed section of vaginal vault
Represents failure of growth
Hypoplasia
Conformational abnormality of the vagina found in medium to large breed dogs. Very common in St.Kitts. Described as a “hooded vulva”
Recessed Vulva
Condition of the vagina where mucosa becomes edematous and protrudes from vulva. Affects young dogs in one of their first proestrus/estrus cycles.
Vaginal edema/hyperplasia
What is the most common neoplasm in the intact female dog?

85-90%
80% adenocarcinoma
A benign mammary lesion that occurs in young cats. Is complicated by trauma, infection and necrosis.
Fibroadenomatous Hyperplasia
Failure of either testicle to descend. Small breeds predisposed. Genetically transmitted.
Cryptorchidism
Origins and their associated hormones of a functional testicular neoplasia.
Sertoli cell- secretes estrogen
Interstitial cell- testosterone
Incomplete formation of the penile urethra
Most common developmental anomaly of external male genitalia.
Most common in Boston Terriers

Adenocarcinoma
Most useful diagnostic tool for simple septal stenosis.
Vaginoscopy
Because you get direct visualization of the stenosis and can evaluate repro and urinary tract.
