Myopericytoma arising adjacent to the common carotid artery: Case report and systematic review of deep located neck myopericytomas

Background Myopericytoma is a perivascular tumor of the skin and subcutaneous tissue of the extremities, it is a rare finding in the head and neck, and even rarer is its deep location. Methods A 38‐year‐old woman presented with a slowly growing mass at the right carotid triangle. Contrast‐enhanced C...

Description
Summary:Background Myopericytoma is a perivascular tumor of the skin and subcutaneous tissue of the extremities, it is a rare finding in the head and neck, and even rarer is its deep location. Methods A 38‐year‐old woman presented with a slowly growing mass at the right carotid triangle. Contrast‐enhanced CT scan revealed a moderately enhancing mass. At surgery, the tumor was firmly attached to the common carotid artery, making it necessary to excise a small portion of the vessel wall. Results The histopathologic report was myopericytoma. The postoperative course was uneventful, without tumor recurrence. Conclusion The very few deep located myopericytomas at the head and neck region show a predilection to appear near the great neck vessels with a possibility to require vascular repair, or at the parotid space where they can be multicentric. © 2016 Wiley Periodicals, Inc.
