Cutaneous malignant melanoma "recurred as" or "in coexistence" with meningioma?

BACKGROUND

The authors report a rare case of a patient with previously treated cutaneous malignant melanoma that recurred 1 year later as an intracranial meningioma.

CASE DESCRIPTION: A 20-year-old woman presented with exophthalmos, diplopia and a mass in the left supraorbital area. Imaging study revealed an enhanced intracranial extradural mass with bone destruction. The patient had a history of cutaneous malignant melanoma surgery on the same location 1 year before. The patient underwent left frontotemporal craniotomy for total resection of the mass. Histological study revealed the intracranial mass to be an atypical meningioma.

CONCLUSION

To our knowledge, this is a rare report of a patient with this tumor occurrence. This case serves to remind neurosurgeons of the potential existence of benign and/ or malignant tumors of neural crest origin.
