Primary Esophageal Meningioma

Abstract

We have described a primary esophageal meningioma (MG) clinical case diagnosed in a 62-year-old woman; also, we review the literature about extracranial MGs. To our knowledge, this is the first case report of an extracranial MG occurring primarily in the esophagus. These are benign neoplasms reported classically in the central nervous system (CNS). The extrancranial MGs have histopathologic and inmunohistochemical features identical to those observed in CNS MGs; thus, the main diagnostic hurdle is to keep it in the differential for lesions occurring outside the CNS.

Metastatic Meningioma Presenting as Cancer of Unknown Primary

“…Firstly, metastatic meningioma is exceedingly rare, especially with appendicular osseous involvement as the presenting site. Other extracranial sites of metastatic disease reported in the literature include lungs, 5 blood vessels, 6 esophagus, 7 and skin. 8 Secondly, the initial biopsy finding at the outside institution was suggestive of poorly differentiated carcinoma, and the primary site was not identified.…”
