Clinical Report: Unique Case of Primary Epithelioid Sarcoma in the Orbit
Background
Epithelioid sarcoma is a rare malignant soft tissue tumor, accounting for less than 1% of all soft tissue sarcomas. The occurrence of primary epithelioid sarcoma in the orbit is exceptionally rare, with no prior documented cases in Asia.
Data Highlights
No numerical data or trial data was presented in the article.
Key Findings
First documented case of primary epithelioid sarcoma of the orbit in Asia.
The patient presented with painless proptosis and an irregular orbital mass.
Histological examination revealed multinodular growth with epithelioid and spindle cells.
Immunohistochemistry showed loss of INI1 expression and co-expression of epithelial and mesenchymal markers.
No local recurrence or distant metastasis was observed at 7 months postoperatively.
Pathological examination is essential for diagnosis due to the tumor's rarity and diagnostic challenges.
Clinical Implications
Histopathological examination is critical in diagnosing rare tumors like primary epithelioid sarcoma.
