malignant myoepithelioma

Tuesday 3 February 2004


Definition: Soft tissue myoepithelioma is a rare tumor displaying myoepithelial elements within a hyalinized to chondromyxoid stroma and lacking obvious ductal differentiation. The histogenesis is unclear and most are benign, but some behave in a malignant fashion.

In the recent WHO classification of tumors of soft tissue and bone, myoepithelioma is considered to be part of a spectrum that also embrases mixed tumor and parachordoma.
