Background:
Primary meningeal melanomas of the central nervous system (CNS) are a rare malignant process with the majority originating from the leptomeninges. Primary dural melanomas have been reported to occur in isolation or in conjunction with Nevus of Ota. The association of primary dural melanoma with multiple cutaneous blue nevi has not been reported previously.
Objective:
To describe a case of a 41-year-old Asian woman patient with a primary dural melanoma that arose in association with ocular melanosis and multiple cutaneous blue nevi. The patient is alive almost more than 8 years after subtotal and subsequent total resection of her primary tumor. Primary dural melanomas, Nevus of Ota, and blue nevi are discussed in relation to their coexistence and potential for intracranial melanoma.
Conclusion:
CNS melanoma is regarded as an extremely aggressive disease with poor prognosis. This case and previous reports of dural melanomas occurring in isolation or with Nevus of Ota have demonstrated relatively prolonged survival after surgical intervention. We conclude that dural melanomas are less aggressive tumors requiring surgical extirpation only.
Insights
Primary dural melanoma, a rare CNS cancer, can be associated with ocular melanosis and blue nevi. Surgical removal offers prolonged survival, suggesting dural melanomas are less aggressive than other CNS melanomas.
Area of Science:
- Neuro-oncology
- Dermatology
- Pathology
Background:
- Primary meningeal melanomas of the central nervous system (CNS) are rare, typically originating from leptomeninges.
- Primary dural melanomas are occasionally linked with Nevus of Ota.
- The association of primary dural melanoma with multiple cutaneous blue nevi is unprecedented.
Observation:
- A case report details a 41-year-old Asian woman with primary dural melanoma.
- The patient presented with ocular melanosis and multiple cutaneous blue nevi.
- The patient remains alive over 8 years post-tumor resection (subtotal and total).
Findings:
- This case highlights a novel association between primary dural melanoma, ocular melanosis, and multiple blue nevi.
- Prolonged survival was achieved through surgical intervention.
- Dural melanomas may exhibit a less aggressive clinical course compared to other CNS melanomas.
Implications:
- The coexistence of these conditions warrants further investigation into their shared etiology.
- Surgical extirpation appears to be a viable and effective treatment for primary dural melanoma.
- This case challenges the perception of CNS melanoma as uniformly aggressive, particularly for dural variants.
