Abstract:
A case of a massive, biopsy-proven, advanced seminoma in the mediastinum 12 years after orchidectomy for a malignant right-sided testicular tumour of unknown histology is presented. The highly unusual nature of this presentation is discussed and may represent either late relapse from skip-metastases or metachronous gonadal and extragonadal tumour development. Immunohistochemical staining was unable to distinguish the site of origin of the lesion.
