1. 11 The histopathologic picture of the nodule over the coccyx showed numerous xanthoma cells and some fibroblastic proliferations.

2. The histopathologic picture of the nodule over the coccyx showed numerous xanthoma cells and some fibroblastic proliferations.

3. 5 The histopathologic picture of the nodule over the coccyx showed numerous xanthoma cells and some fibroblastic proliferations.

4. Centrioles were observed in angiomatous meningiomas, but cilia and other ciliary structures were found only in the endotheliomatous and fibroblastic meningiomas.

5. The occurrence of cilia and related structures were studied electron-microscopically in 14 endotheliomatous, 3 fibroblastic, and 3 angiomatous meningiomas.

6. Nodular fasciitis is a common benign proliferative fibroblastic tumor in the limbs of adults, but rare in the head and neck of children.

7. Endotheliomatous and transitional forms constituted 85% of the total (71.5% of intracranial tumors), fibroblastic forms 6.6 and 7.5%, respectively, and highly vascularized (endotheliomatous or transitional) meningiomas 5.2% of the intracranial tumors, while true “angioblastic” meningiomas (hemangioblastomas and hemangiopericytomas) amounted to 2.8% of the total (3.1% of the intracranial tumors). 1.2% were “atypical” (so-called malignant) meningiomas; true meningeal sarcomas were excluded.
