Summary
Orbital angiosarcoma, a rare endothelial cell tumor, can present as exophthalmos. This case highlights the challenges in diagnosing and treating this aggressive cancer, even with extensive intervention.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Angiosarcoma is a rare malignant endothelial cell tumor.
- Primary orbital angiosarcoma is exceptionally uncommon, with limited case reports available.
- Orbital tumors can present with varied symptoms, including proptosis and diplopia, necessitating thorough diagnostic evaluation.
Observation:
- A 46-year-old woman presented with progressive diplopia and right exophthalmos.
- Initial imaging suggested a cavernous hemangioma, while ultrasound indicated a metastatic lesion.
- Biopsy confirmed angiosarcoma, histologically similar to a prior breast angiosarcoma.
Findings:
- The orbital mass was diagnosed as angiosarcoma via histopathology and immunohistochemistry.
- Despite surgical intervention (subtotal excision and orbital exenteration), the tumor recurred.
- The patient succumbed to the disease despite aggressive multidisciplinary treatment.
Implications:
- This case underscores the diagnostic challenges of orbital angiosarcoma, often mimicking benign or metastatic lesions.
- Aggressive management, including surgery and multidisciplinary care, may not prevent recurrence in advanced orbital angiosarcoma.
- Further research into the pathogenesis and treatment of orbital angiosarcoma is warranted to improve patient outcomes.
