Orbital metastasis from cutaneous melanoma.
Southern Medical Journal
|November 1, 1986
Summary
Orbital metastasis from cutaneous melanoma is rare. This report details two unique cases, presenting the first CT and MRI findings for this condition in advanced melanoma.
Area of Science:
- Oncology
- Ophthalmology
- Medical Imaging
Background:
- Orbital extension is common in ocular melanoma, but rare in cutaneous melanoma.
- Orbital metastasis from cutaneous melanoma has been documented only eight times previously.
Observation:
- Two cases of cutaneous melanoma with orbital metastasis are presented.
- One patient had a history of three primary melanomas.
- The other patient had metastasis to the cauda equina.
Findings:
- Both patients developed orbital involvement years after initial cutaneous melanoma diagnosis.
- Both patients died following the development of orbital metastasis.
- These are the first reported cases including CT and MRI findings of metastatic orbital melanoma.
Implications:
- Highlights the potential for late orbital metastasis from cutaneous melanoma.
- Emphasizes the importance of advanced imaging (CT and MRI) in diagnosing and managing rare melanoma presentations.
- Suggests a poor prognosis once orbital metastasis occurs in cutaneous melanoma.
