Summary
This case report details a rare instance of ocular choroidal melanoma metastasizing to the pelvis in a teenage girl. Surgical reconstruction with a hemipelvic prosthesis led to excellent functional recovery and no recurrence.
Area of Science:
- Oncology
- Ophthalmology
- Orthopedic Surgery
Background:
- Choroidal melanoma is a rare primary ocular malignancy.
- Metastasis from choroidal melanoma typically occurs to distant organs like the liver or lungs.
- Pelvic metastasis from choroidal melanoma is exceptionally rare.
Observation:
- A 16-year-old female presented with right hip pain and claudication.
- Imaging revealed an osteolytic lesion with a soft tissue mass in the right hemipelvis.
- SPECT and PET-CT confirmed no other metastatic sites.
Findings:
- The patient underwent tumor resection and hemipelvic prosthesis reconstruction.
- Pathological diagnosis confirmed metastatic malignant melanoma.
- Postoperative follow-up showed no evidence of recurrence at 30 months.
Implications:
- This case highlights the potential for late and unusual metastasis from choroidal melanoma.
- Hemipelvic prosthesis reconstruction is a viable option for pelvic tumor resection.
- This represents a unique case of ocular melanoma metastasis to the pelvis with successful surgical management.
