Primary intracranial pleomorphic angioleiomyoma—A New Morphologic Variant. An immunohistochemical and electron microscopic study

BACKGROUND: Angioleiomyomas usually are benign subcutaneous neoplasms that occur most often in extremities of middle-aged individuals. Very few cases have been described in other locations; none along the neuroaxis. An intracranial example of angioleiomyoma displaying unusual morphologic features not seen in the typical peripheral variants of this tumor is described. METHODS: The tumor was studied with conventional histology, …
