title: Extragonadal endodermal sinus tumours. Report of a case.
abstract: A case is described of endodermal sinus tumour originating in the sacro-coccygeal region in a man 20 years of age. Of the hitherto presented cases of endodermal sinus tumour of a gonadal origin, 24 out of 42 patients have died. Of 21 patients in whom the disease was of an extragonadal origin, 18 have died. Thus, the prognosis seems to be less favourable in patients with extragonadal tumours. The best prognosis has been reported in boys with endodermal sinus tumours of a testicular origin operated before the age of 2 years.
