Epithelioid cell lesions are very common in pathology.
Malignant epithelioid lesions are usually a carcinoma.
A short differential diagnosis:
- Carcinoma (primary and metastatic).
- Malignant melanoma.
- Sarcoma.
Epithelioid sarcomas
All rules are made to be broken... some epithelioid lesions are sarcomas:[1]
- Epithelioid sarcoma.
- Epithelioid angiosarcoma.
- Alveolar soft part sarcoma.
- Rhabdoid tumour.
Others:
- Clear cell sarcoma.
- Epithelioid gastrointestinal stromal tumour.
- Synovial sarcoma, primitive round cell type.
- Sarcomas in the small round cell tumours group, e.g. Ewing sarcoma.
An exhaustive DDx of large epithelioid tumour is in large epithelioid tumours.
