An ectopic hamartomatous thymoma is an extremely rare benign tumor of the lower neck that is the most common in middle-aged males. Pathologically, the tumor is characterized by a mixture of spindle cells, epithelial cells, mature adipose tissue, and lymphocytes. The histogenesis of this tumor is controversial. Recently, an origin from a remnant of the cervical sinus of His was proposed. Malignant lesions such as synovial sarcomas or malignant peripheral nerve sheath tumors can have similar clinical features and radiologic images. Thus, recognition of this tumor is important because it follows a benign clinical course and conservative surgical excision is the treatment of choice. Here, we report the case of a 34-year-old man with an ectopic hamartomatous thymoma in the left supraclavicular region and a review of the literature on this tumor.
异位错构瘤性胸腺瘤是一种极其罕见的下颈部良性肿瘤，多见于中年男性。病理上，该肿瘤的特征是梭形细胞、上皮细胞、成熟脂肪组织和淋巴细胞混合存在。这种肿瘤的组织发生存在争议。最近，有人提出其起源于希氏颈窦残余。滑膜肉瘤或恶性外周神经鞘瘤等恶性病变可能具有相似的临床特征和影像学表现。因此，认识这种肿瘤很重要，因为它临床过程良性，保守性手术切除是首选治疗方法。在此，我们报告一例34岁男性左锁骨上区异位错构瘤性胸腺瘤病例，并对该肿瘤的文献进行综述。
