Amyloid stroma in meningiomas.
Twenty-three cases of meningiomas with psammoma bodies (PBs) and 15 without PBs have been studied using histochemical, ultrastructural and immunohistochemical methods for amyloid. Amyloid was found in all cases showing PBs and in only 5 cases in the group devoid of PBs. Meningiomas may contain amyloid in their stroma.
