RESUMO
Epithelioid sarcoma-like hemangioendothelioma (ES-H) is a rare, indolent vascular neoplasm with characteristics similar to epithelioid sarcoma. It typically affects young males who present with skin and subcutaneous lesions in the extremities. Bone lesions, occurring in approximately 20% of patients, are often multifocal, seen in conjunction with soft tissue lesions, and usually found in bones of the lower extremities. This report details the case of a 20-year-old male who presented with a 1-year history of painful skin lesions on his left lower extremity. Staging studies revealed bone lesions in the cuboid and calcaneus. Bone and soft tissue pathology was consistent with ES-H. The soft tissue lesions were treated with wide excision and the bony lesions with radiofrequency ablation (RFA). The patient had no evidence of recurrence at the 2-year follow-up. Treatment of ES-H typically consists of wide excision of all soft tissue lesions and possible adjuvant radiation therapy. Management of bony lesions has included marginal excision, wide excision, amputation, chemotherapy, observation, or a combination of these modalities. ES-H has the potential for distant metastases. There is no consensus regarding the appropriate treatment of multifocal epithelioid sarcoma-like hemangioendothelioma involving bone. A potential treatment strategy of wide excision of soft tissue lesions and RFA of bone lesions is proposed.
