Epithelioid sarcoma (ES) is a high-grade, soft tissue tumor of mesenchymal origin that rarely occurs in children and is often misdiagnosed as a benign entity. We present the case of a 12-year-old girl with a delayed diagnosis of ES of the left thumb. Radiological examination showed possible calcinosis from inflammation or traumatic injury. However, histopathological and immunohistochemistry studies showed findings consistent with a diagnosis of ES. She was treated with amputation of the interphalangeal joint of the left thumb. This case highlights the clinical and pathologic correlation required for the appropriate diagnosis and treatment of patients with soft tissue masses.
上皮样肉瘤（ES）是一种罕见于儿童的源自间叶组织的高级别软组织肿瘤，常被误诊为良性肿瘤。我们报告了一例 12 岁女孩左拇指延迟诊断的 ES 病例。影像学检查显示炎症或创伤性损伤所致的钙沉积可能性。然而，组织病理学和免疫组织化学研究显示的结果符合 ES 的诊断。她接受了左拇指近节指间关节切除术。该病例强调了正确诊断和治疗软组织肿块患者所需的临床和病理相关性。
