What is epithelioid morphology?
Epithelioid morphology, mimicking carcinoma, is a key or defining feature of several soft tissue tumors and may be seen in a wide variety of other tumors.

What is epithelioid sarcoma?
Epithelioid sarcoma (ES) is a rare, slow-growing, soft-tissue sarcoma with granuloma-like appearance. The epithelioid cells in both human tuberculosis and sarcoidosis are also ‘primarily biosynthetic rather than phagocytic’. Epithelioid reticular cells were arranged concentrically and interpreted as Hassall corpuscles.
