[Testicular choriocarcinoma with pure histological pattern. Necropsy study in a representative case]

Pure testicular choriocarcinoma is a relatively infrequent neoplasia with an ominous prognosis.

We report the necropsy study of a 21-year old male patient with generalized metastases of a primary pure testicular choriocarcinoma.

The aggressiveness of this neoplasia is demonstrated by extensive tumor dissemination in early stages, in which testicular clinical manifestations are often absent.

In front of any choriocarcinoma it is imperative to perform an extensive sampling of the lesion with the aim to detect possible foci of germ cell neoplasia which constitute a mixed pattern.
