Elastosis in meningioma

A 63-year-old woman underwent a left craniotomy for the removal of a middle cranial fossa meningioma. Microscopically, the tumor showed a transitional and fibroblastic histological pattern. Within the tumoral tissue there were collagenous foci where little eosinophilic masses were found. This compon...

Description
Summary:A 63-year-old woman underwent a left craniotomy for the removal of a middle cranial fossa meningioma. Microscopically, the tumor showed a transitional and fibroblastic histological pattern. Within the tumoral tissue there were collagenous foci where little eosinophilic masses were found. This component corresponded to elastic material with typical staining properties. Such features disappeared when the histological slides were incubated with elastase. Elastosis is very uncommon feature observed in meningiomas, with an uncertain significance.
