title: Extragonadal malignant teratoma of the foot.
abstract: This report documents the occurrence of an extragonadal malignant teratoma on the sole of the foot, in a young male. The patient also developed a groin nodule showing the same histology. The testes, retroperitoneum and mediastinum, which are usual sites of germ cell tumours were all normal, and no other primary could be detected. A teratoma growing in the tip of an extremity is a unique occurrence, biologically difficult to explain, and, which to the best of our knowledge has never been reported in literature.
