title: Primary seminoma in the middle mediastinum.
abstract: Primary mediastinal seminoma is a relatively rare tumor usually located in the anterior mediastinum. We report here an extremely rare case of a 66-year-old man with primary seminoma in the middle mediastinum. A physical examination showed lymphadenopathy in the right supraclavicular area. A chest CT confirmed the presence of a tumor occupying the retrotracheal space. A histological examination demonstrated metastatic seminoma from the open biopsy of the lymph node. Abdominal, pelvis, and cerebral CT scan and testicular ultrasound were negative. Thus, primary mediastinal seminoma in the middle mediastinum with supraclavicular lymph node metastasis was diagnosed.
