Metastatic myoepithelial carcinoma in a child.

Cutaneous myoepithelial tumors are rare entities, with few reported malignant variants in the literature. The majority of these tumors are reported in the head and neck region of the adult population, with few examples in the literature arising in young patients. We present a case of myoepithelial carcinoma in a 13-year-old girl, with documented metastatic disease. Reproducible predictors of malignant behavior have yet to be clarified.
