Scope note: Neoplasia maligna radiosensible de los testículos que se supone derivada de las células germinales primordiales de la gónada embrionaria sexualmente indiferenciada. Se identifican tres variantes histológicas: clásico (típico), que es el tipo más frecuente, anaplásico y espermatocítico. El seminoma clásico está compuesto de láminas o cordones de células poligonales o redondas uniformres (células de seminoma); cada céula tiene abundante citoplasma claro, membranas celulares distintas, un núcleo redondo central y uno o más nucleólos. En las mujeres, se produce una neoplasia macroscópica y microscópicamente idéntica, conocida como disgerminoma. (Dorland, 27th ed)

Scope note: 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. (Dorland, 27th ed)
