Abstract
✓ A case of meningeal fibroma in a 5-year-old girl is described. The lesion presented as a benign intracranial tumor, eroding the frontal bone and protruding under the skin. It was composed of fibroblasts and collagen, embedded in a loose background with focal myxoid changes. The authors describe the patient's clinical presentation and the tumor's histological, immunohistochemical, and ultrastructural features, and discuss its differential diagnosis. It is concluded that fibromas of the meninges should be distinguished from fibroblastic meningiomas.
