Primary mediastinal seminoma is an uncommon tumor usually located in the anterior mediastinum. The majority of cases occur in young males. We report here an extremely rare case of a 69-year-old male with primary seminoma in the middle mediastinum. The patient had no complaints, but an abnormal shadow was seen in a routine chest X-ray. We performed a tumorectomy in the middle mediastinum, a thymectomy and an orchidectomy and added postoperative chemotherapy. It seems that the tumor was not associated with the thymus, so we believe the tumor did not stem from the embryonic thymus. Our case demonstrated that mediastinal seminoma does not always occur in the anterior mediastinum of young males. Although this case is rare, seminoma should be included among the possible diagnoses of a middle mediastinal mass.
原发性纵隔精原细胞瘤是一种罕见肿瘤，通常位于前纵隔。大多数病例发生在年轻男性。我们在此报告一例极其罕见的69岁男性原发性精原细胞瘤位于中纵隔的病例。患者无不适症状，但在常规胸部X线检查中发现异常阴影。我们在中纵隔进行了肿瘤切除术、胸腺切除术和睾丸切除术，并术后进行了化疗。肿瘤似乎与胸腺无关，因此我们认为该肿瘤并非起源于胚胎胸腺。我们的病例表明，纵隔精原细胞瘤并不总是发生在年轻男性的前纵隔。尽管该病例罕见，但精原细胞瘤应纳入中纵隔肿块的可能诊断之中。
