Overview
Pathogenesis
- Epithelioid sarcoma is the second most common soft tissue sarcoma in hand. Epithelioid sarcoma is also sixth most common soft tissue sarcoma in upper extremity.
- Primary site of epithelioid sarcoma is upper distal extremities. Other rare sites of epithelioid sarcoma are:
- Vulva
- Penis
- Spine
- Epithelioid sarcoma is a rare soft tissue sarcoma arising from mesenchymal tissue and characterized by epithelioid-like features.
- Epithelioid sarcoma accounts for less than 1% of all soft tissue sarcomas. It was first clearly characterized by F.M. Enzinger in 1970.[1] It commonly presents itself in the distal limbs (fingers, hands, forearms, or feet) of young adults as a small, soft mass or a series of bumps. A proximal version has also been described, frequently occurring in the upper extremities.[2] Rare cases have been reported in the pelvis, vulva, penis, and spine.
- Epithelioid sarcoma most commonly strikes young adults, yet no age group is immune. The disease has a tendency to develop local recurrences and metastasis thereafter to regional lymph nodes, lung, bone, brain, and other locations, including the scalp.[3] Generally speaking, epithelioid sarcoma has a high rate of relapse after initial treatment and tends to recur locally (at or near the original tumor site). Epithelioid sarcoma also demonstrates lymphatic spread (in 22-48% of cases), and metastasis (in 21-63% of cases).[4] These events, as well as advanced stage (progression) and grade (aggressiveness), are predictive of an overall worse outcome. The overall five-year survival rate for epithelioid sarcoma is anywhere from 25 to 78%.[4] Importantly, the 10-year and 15-year survival rate drops off significantly.[5][6] Associated with a more positive outcome are younger age, female vs. male sex, distal vs. proximal location, smaller tumor size, and negative margins upon tumor resection.[1][7][6]
Genetics
SMARCB1 gene is involved in the pathogenesis of epithelioid sarcoma.
Associated Conditions
Gross Pathology
Microscopic Pathology
- Histologically, epithelioid sarcoma forms nodules with central necrosis surrounded by bland, polygonal cells with eosinophilic cytoplasm and peripheral spindling.[3] Epithelioid sarcomas typically express vimentin, cytokeratins, epithelial membrane antigen, and CD34, whereas they are usually negative for S100, desmin, and FLI-1.[3] They typically stain positive for CA125.[8]
