title: Myopericytoma of lip: a rare lesion in an unusual location.
abstract: Myopericytoma is a rare benign tumor with perivascular myoid differentiation. It shares histomorpholoic features with the so-called hemangiopericytoma, myofibroma and glomus tumor. We hereby report the case of a 14-year-old boy who presented with a slowly growing, painless, firm mass on upper lip, diagnosed as myopericytoma on the basis of histopathology and immunohistochemistry. To the best of our knowledge, this is only the second such reported case.
