Summary
An 11-year-old Labrador Retriever presented with oestrus signs and vaginal bleeding, diagnosed with an ovarian granulosa cell tumor. Successful surgical and chemotherapeutic treatment showed no recurrence, highlighting effective management of canine reproductive cancers.
Area of Science:
- Veterinary Oncology
- Reproductive Endocrinology in Canines
Background:
- A spayed 11-year-old female Labrador Retriever exhibited clinical signs of oestrus and vaginal bleeding.
- The patient had a history of being spayed at less than 6 months of age and had not previously cycled.
Observation:
- Clinical presentation included signs of oestrus and vaginal bleeding.
- Diagnostic investigations revealed an ovarian granulosa cell tumor.
Findings:
- The dog had a prior history of localized grade III mast cell tumor and hepatic hemangiosarcoma.
- Both previous conditions were successfully treated with surgery and chemotherapy.
Implications:
- This case demonstrates the successful management of a complex oncological case in a canine patient.
- Early diagnosis and multimodal treatment (surgery and chemotherapy) are crucial for managing ovarian granulosa cell tumors and concurrent or prior malignancies in dogs.

01:24Disorders of the Female Reproductive System
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
