[Embryonal carcinoma and anaplastic seminoma of the testis: diagnostic difficulties].
In this case report concerning a testicular tumor, the difficulty of discriminating between embryonic carcinoma with granulomatous reaction and anaplastic seminoma is described. According to the literature and the findings of the present case, the value of immunohistochemical investigations is emphasized, especially the use of anti cytokeratin antibody in the diagnosis of embryonic carcinoma. Therapeutic issues stress the importance of such a diagnosis. Furthermore the immunohistochemical identification of embryonic carcinoma in every case should lead to a new classification of the so-called anaplastic seminoma's entity.
