Seminoma Presenting as a Mediastinal Mass in an Elderly Patient.

Primary mediastinal germ cell tumors are relatively rare and represent 10% - 20% of all mediastinal tumors. About one-third of these are primary mediastinal seminomas, occurring in males in their third and fourth decades, with the median age of presentation ranging between 20 and 30 years of age. We report an unusual case of a 69-year old male with mediastinal seminoma, who presented at an age much higher than the usual affected patient and responded well to the conventional mode of therapy for this tumor. A review of literature pertaining to clinical presentation, diagnosis, and management is also presented.
