Abstract

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms classified by the World Health Organization (WHO) as tumors of uncertain differentiation. They are composed of perivascular epithelioid cells (PECs), which are characterized by their distinctive morphology, close association with blood vessel walls, and dual expression of melanocytic and smooth muscle markers [1].
