Parotid Gland Adamantinoma-Like Ewing Sarcoma

Preferred Label : Parotid Gland Adamantinoma-Like Ewing Sarcoma;

NCIt synonyms : Parotid Gland ALES;

NCIt definition : An exceedingly rare variant of Ewing sarcoma with epithelial differentiation that resembles carcinoma and arises from the parotid gland. Morphologically, it is characterized by the presence of nests of basaloid cells, tumor cell palisading, myxoid or hyalinized stroma, focal keratin pearl formation, and high-grade features with minimal pleomorphism.;

Neoplastic status : Malignant;
