Anaplastic seminoma.
Fourteen patients with anaplastic seminoma were analyzed retrospectively. At the time of presentation anaplastic seminoma has similar prognosis stage for stage as the classic seminoma. However, the distinctive histologic findings and the high rates of local invasion and of elevations of serum beta-subunit human chorionic gonadotropin serve to distinguish anaplastic seminoma from the classic seminoma. These features, suggesting a possibly greater metastatic potential for anaplastic seminoma, warrant its continued identification as a distinct pathologic subtype.
