Abstract

This case report discusses a cervical psammomatous melanotic schwannoma - a rare form of peripheral nerve sheath tumour - which may be highly vascular and is often associated with the Carney complex. Significant intraneural bleeding, which was encountered intraoperatively, was controlled successfully with a gelatine-based thrombin haemostatic agent (Floseal®, Baxter International, Deerfield, IL, USA) without complication.

Keywords: Carney complex; Psammomatous; Schwannoma; Vascular.
