Myoepitheliomas of the skin and soft tissue - A clinicopathologic study of three cases

Myoepithelioma of the skin and soft tissue is a newly recognized entity with characteristic histopathologic and immunohistochemical features, which should be differentiated from a variety of tumors. Myoepitheliomas are in the same pathologic spectrum of mixed tumors and parachordomas. Tumors comprised mostly of myoepithelial cells without obvious epithelial differentiation are designated myoepitheliomas. Since the entity has not been well documented in Taiwan, the clinicopathologic features of three cases of cutaneous and soft tissue myoepitheliomas are reported.
