Large epithelioid tumours are common and represent a large differential diagnosis when viewed generally.
Malignant epithelioid lesions are often carcinomas... but may be a large number different tumours.
A more general discussion of epithelioid lesions is in the epithelioid cell lesions article. Small epithelioid lesions are dealt with in the small round cell tumours article.
