title: Myopericytoma presenting as multiple pulmonary nodules.
abstract: Myopericytoma is a benign tumor composed of cells that show apparent differentiation towards putative perivascular myoid cells called myopericytes. To date, only a small number of series describing myopericytomas have been reported. Here, we report a case of pulmonary myopericytoma presenting as multiple nodules in a 26-year-old man. Clinical presentation, radiological features and histopathologic findings of the patient are also discussed. The result of the histology combined with the immunohistochemical analysis led to a diagnosis of myopericytomas. To our knowledge, this is the first report of myopericytoma showing pulmonary involvement.
