Epithelioid sarcoma (ES) is a rare cancerous tumor that most often occurs in the soft tissue of the fingers, hands and forearms of young adults. It can also occur elsewhere in the body. ES usually begins as a painless, firm growth or bump that may be accompanied by an open wound (ulceration) in the skin covering the growth. This type of tumor often comes back after treatment or spreads to other parts the body (metastasis). The cause of epithelioid sarcoma is unknown. It is diagnosed by a clinical examination and by testing a small sample of the tumor (biopsy) in a laboratory. Epithelioid sarcoma is treated with surgery to remove all the cancer cells (wide local excision) and sometimes with radiation therapy. Chemotherapy may also be used if the cancer has spread to other parts of the body.
