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.
