Micrograph of an epithelial-myoepithelial carcinoma (right of image). The epithelial component has a tubular morphology and is evident only focally (upper left of image). Benign serous glands (parotid salivary gland) are also seen (left of image). H&E stain.
Epithelial-myoepithelial carcinoma, abbreviated EMCa, is a rare malignanttumour that typically arises in a salivary gland and consists of both an epithelial and myoepithelial component. They are predominantly found in the parotid gland and represent approximately 1% of salivary gland tumours.
