Abstract: A 27-year-old man was transferred to our hospital with the complaint of facial edema and diagnosis of giant anterior mediastinal tumor. But soon after admission, the size of the tumor decreased remarkably, although he had no particular treatment. As the tumor was not completely regressed, surgical resection was performed subsequently, and examination of the specimen showed small foci of seminoma within the area of dense fibrous scar tissue, originated from the thymus. While regression of germ cell tumors are well recognized in cases of nonseminomatous germ cell tumors, this phenomenon of primary mediastinal seminoma was not reported previously.
