A Case of Intravascular Myopericytoma Located in the Neck.

Background: Myopericytomas are rare tumors originating from perivascular myoid cells, with overlapping features of glomus tumors and myofibromas. Case Report: We present a case of intravascular myopericytoma, a rare variant of myopericytomas, with a mass located in the neck. This case is accompanied by a review of the relevant literature discussing its histomorphological and immunohistochemical features. In histopathology, this tumor is characterized by spindle or epithelioid cells that surround the vessels in a concentric pattern. Conclusion: While these tumors most commonly occur in extremities, they are rarely seen in the head, neck, and trunk. Even though they are generally considered benign, it's important to note that cases showing increased mitotic activity, recurrence, and metastasis have been reported.
