Preferred Label : seminoma;
Definition : A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial
germ cells of the sexually undifferentiated embryonic gonad. There are three variants:
classical (typical), the most common type; anaplastic; and spermatocytic. The classical
seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal
or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct
cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the
female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs.
