Mandibular vascular hamartoma in a cat

Area of Science:

• Veterinary Medicine
• Oncology
• Pathology

Background:

• Vascular hamartomas are rare benign tumors often presenting asymptomatically.
• Oral masses in cats can lead to significant clinical signs, including bleeding and difficulty eating.
• Accurate histopathological diagnosis is crucial for understanding tumor behavior and prognosis.

Observation:

• A 10-year-old cat exhibited a one-month history of excessive salivation and oral bleeding.
• Physical examination revealed a palpable mass on the right mandible.
• Computed tomography demonstrated extensive bone proliferation associated with the mandibular mass.

Findings:

• Mandibular bone biopsy confirmed the histopathological diagnosis of vascular hamartoma.
• The tumor involved significant mandibular bone proliferation.

Implications:

• This case highlights the potential for vascular hamartomas to cause severe oral pathology in cats.
• The sudden death of the cat suggests potential complications or rapid progression despite the benign nature of the hamartoma.
• Further research into the behavior and management of feline vascular hamartomas is warranted.
