Primary sellar glomus tumor with BRAF K601E mutation: an aggressive tumor of uncertain malignant potential.

Abstract excerpt

Glomus tumor (GT) is a mesenchymal neoplasm composed of modified perivascular cells exhibiting smooth muscle-like features, resembling those of the normal glomus body. The lesions often occur in areas rich in glomus vascularis, most of which occur in the distal limbs, while the sellar GT is extremely rare. Here, we present a case of primary sellar GT harboring a BRAF K601E mutation, identified through...
