Testicular germ cell tumour representing with spontaneous, comprehensive or partial neoplastic retrogression configures as regressed testicular germ cell tumour. Tumefaction manifests with distant metastasis, residual testicular germ cell tumour or a dual component comprising of residual neoplasm and distant metastasis. Additionally designated as regressed germ cell tumour, burned out germ cell tumour or burnt out germ cell tumour, neoplasm is commonly associated with pure seminoma delineating distant metastasis and residual testicular tumour. Morphological composition of testicular tumour regression is comprised of fibrous scar and germ cell neoplasia in situ.
