Myopericytoma in the oral cavity: a rare case report and literature review.

Myopericytoma (MPC) is a rare, benign, and cellular mesenchymal neoplasm. Histologically, it is characterized by concentric perivascular proliferation of spindle-shaped tumor cells. While MPCs predominantly occur in the subcutaneous or superficial soft tissues of distal extremities, oral MPCs are exceptionally rare. Herein, we present a case of MPC located in the sublingual region of a 74-year-old male. Additionally, we conducted a systematic review of 29 previously reported cases to delineate the clinicopathological and molecular features of MPC. This comprehensive analysis aims to improve diagnostic accuracy and enhance the cognition of this uncommon tumor entity's clinicopathological characteristics and biological behavior.
