Epithelioid sarcoma of the upper extremity

Area of Science:

• Orthopedic Oncology
• Surgical Pathology
• Soft Tissue Tumors

Background:

• Epithelioid sarcoma is a rare malignant soft-tissue neoplasm.
• Diagnosis can be challenging due to its varied presentation.
• This study reviews existing literature and presents new cases.

Observation:

• Three new cases of epithelioid sarcoma in the upper extremity were analyzed.
• A comprehensive review of 112 previously reported cases was conducted.
• The clinical and pathological features of epithelioid sarcoma were examined.

Findings:

• Epithelioid sarcoma should be considered in the differential diagnosis of upper extremity soft-tissue tumors.
• Early and aggressive surgical intervention is crucial for effective management.
• Current data do not support the efficacy of irradiation therapy or chemotherapy.

Implications:

• Highlights the importance of including epithelioid sarcoma in the differential diagnosis for extremity soft-tissue lesions.
• Emphasizes the necessity of prompt surgical management for optimal patient outcomes.
• Suggests a focus on surgical resection over adjuvant therapies like radiation and chemotherapy.
