摘要
骨外尤文氏肉瘤在颈部软组织,尤其是胸锁乳突肌中极为罕见。其临床表现通常为迅速生长的肿块,极有可能发生局部扩散。本文旨在介绍一例罕见的胸锁乳突肌骨外尤文氏肉瘤病例。据我们所知,这是第一例发生在该部位的骨外尤文氏肉瘤。患者因颈部肿瘤入院。计算机断层扫描结果显示,肿瘤肿块大部分位于颈部 V 区,大小为 40 × 27 × 35 毫米。病理组织学和免疫组化结果显示,这是尤文氏肉瘤。不幸的是,患者在确诊九个月后去世。骨外尤文肉瘤是一种罕见的快速生长恶性肿瘤,其组织形态与骨尤文肉瘤相似。大多数报告指出,骨外尤文肉瘤的预后比骨骼型尤文肉瘤差。在鉴别诊断颈部软组织肿瘤时应注意骨外尤文肉瘤。
Primary Cervical Extraosseous Ewing's Sarcoma Originated from the Sternocleidomastoid Muscle: A Case Report and Review of the Literature.
Extraosseous Ewing's sarcoma is extremely rare in the soft tissues of the neck, especially in the sternocleidomastoid muscle. It usually manifests clinically as a rapidly growing mass that shows great potential for local spread. The aim of this paper is to present a rare case of еxtraosseous Ewing's sarcoma in the sternocleidomastoid muscle. To the best of our knowledge, this is the first case of extraskeletal Ewing's sarcoma at this location. The patient was admitted to our clinic because of a neck tumefaction. The computerized tomography finding showed a tumor mass, most of which was in the V region of the neck, measuring 40 × 27 × 35 mm. Pathohistological and immunohistochemical findings showed that it was Ewing's sarcoma. Unfortunately, the patient passed away nine months after the initial diagnosis. Extraosseous Ewing sarcoma is a rare, fast-growing malignant tumor manifesting histomorphological similarities to bone Ewing's sarcoma. Most reports state that extraosseous Ewing sarcoma has a worse prognosis than skeletal. Extraosseous Ewing sarcoma should be borne in mind in the differential diagnosis of soft tissue tumors of the neck.
