Orbital Epithelioid Sarcoma: A Case Report

Epithelioid sarcoma is a rare but often aggressive malignancy of soft tissue that usually occurs in young adults as a superficial lesion in the distal upper limbs. To date, there are only 4 case reports of epithelioid sarcoma primarily occurring in the orbit. Two of these patients were treated with primary exenteration only one of whom was alive 3 years after diagnosis. Radical surgical excision is thus the first treatment of choice for primary orbital epithelioid sarcoma. The authors present a patient with primary orbital epithelioid sarcoma who refused exenteration. Surgical debulking followed by local brachytherapy was performed. The patient remains tumor free 5 years after diagnosis. The literature remains limited regarding treatment options for primary orbital epithelioid sarcoma. However, based on reported cases and this case, the authors conclude that surgical excision combined with local iridium radiation therapy is an acceptable treatment when treating primary orbital epithelioid sarcoma
