Findings

No curated finding names diffuse meningeal melanocytosis yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

A diffuse or multifocal proliferation of uniform nevoid polygonal cells in the leptomeninges. Cells may spread into the Virchow-Robin spaces without frank invasion of the brain. Diffuse melanocytosis carries a poor prognosis even in the absence of histologic malignancy. (WHO)
