Cellular Classification of Testicular Cancer
The following histologic classification of malignant testicular germ cell tumors (testicular cancer) reflects the classification used by the World Health Organization (WHO). Less than 50% of malignant testicular germ cell tumors have a single cell type, of which roughly 50% are seminomas. The rest have more than one cell type, and the relative proportions of each cell type should be specified. The cell type of these tumors is important for estimating the risk of metastases and the response to chemotherapy. Polyembryoma presents an unusual growth pattern and is sometimes listed as a single histologic type, though it might better be regarded as a mixed tumor.[1,2,3]
