Summary

This report details a rare canine case of multiple congenital lymphangiomas, a type of lymphatic hamartoma. Surgical treatment was successful after recurrence, offering insights into managing these complex lymphatic malformations.

Area of Science:

  • Veterinary Medicine
  • Pathology
  • Surgical Oncology

Background:

  • Lymphangiomas are benign congenital tumors originating from lymphatic vessels.
  • While common in humans, multiple lymphangiomas with lymph node involvement are exceptionally rare in canines.
  • This case involves a seven-month-old Golden Retriever presenting with extensive cystic masses.

Observation:

  • The patient exhibited numerous cystic masses in the inguinal and caudal mammary regions.
  • Histopathological examination revealed lymphatic endothelial cells expressing factor VIII-related antigen and smooth muscle, consistent with human lymphangiomas.
  • A comprehensive literature review found no similar canine cases with these specific characteristics.

Findings:

  • The dog was diagnosed with congenital lymphangiomas (lymphatic hamartomas).

  • Initial surgical intervention resulted in tumor recurrence.
  • A second surgical procedure led to a disease-free outcome for the patient.

    • Implications:

    • This case expands the understanding of lymphangioma presentation and behavior in veterinary patients.
    • The findings suggest that surgical management, even after recurrence, can be effective for canine lymphangiomas.
    • Further research into the specific cellular markers and etiology of canine lymphangiomas is warranted.
