Epithelioid hemangioma of bone is a rare benign vascular tumor. Because of the locally destructive clinical presentation and the presence of atypical histologic features with increased mitotic activity and necrosis, it is often misdiagnosed as low-grade malignant epithelioid hemangioendothelioma or high-grade malignant epithelioid angiosarcoma. Correct diagnosis through imaging studies and histopathological examination is mandatory to determine the appropriate course of treatment, as the prognosis differs from that of other malignant hemangioma tumors. A 69-year-old male who presented with intractable shoulder pain caused by epithelioid hemangioma in the acromion of the scapula was treated with tumor curettage. This paper reports a good result with a review of the relevant literature.
