Orbital chondroma rodens in a dog
Journal of the American Veterinary Medical Association
|July 15, 1979
Summary
A canine chondroma rodens in the orbit was surgically removed and treated with radiation therapy, showing positive outcomes. This condition differs from the human juvenile aponeurotic fibroma.
Area of Science:
- Veterinary Ophthalmology
- Comparative Pathology
- Oncology
Background:
- A 9-year-old dog presented with chronic unilateral epiphora, indicative of orbital abnormalities.
- Ophthalmic examination revealed a space-occupying mass in the superficial medial aspect of the right orbit.
Purpose of the Study:
- To describe the diagnosis, surgical management, and therapeutic outcomes of chondroma rodens in a canine patient.
- To differentiate canine chondroma rodens from human juvenile aponeurotic fibroma based on histologic and epidemiologic features.
Main Methods:
- Surgical excision of the orbital mass.
- Histopathologic examination of the excised tissue.
- Radiation therapy as an adjunct treatment for residual or recurrent tumor.
- Comparative analysis of histologic and epidemiologic data with human counterparts.
Main Results:
- Chondroma rodens was diagnosed in the canine orbit.
- Initial excision was followed by recurrence, necessitating further surgical intervention.
- Radiation therapy yielded encouraging results in managing the tumor.
- Canine chondroma rodens exhibits distinct histologic and epidemiologic features compared to human juvenile aponeurotic fibroma.
Conclusions:
- Chondroma rodens is a distinct entity in dogs, requiring multimodal treatment including surgery and radiation therapy.
- The condition is not directly analogous to human juvenile aponeurotic fibroma due to significant differences.
