germ cells
sertoli or leydig cells (sex cord-stromal tumors)
germ cell tumors are divided into 2 groups:
seminomas
non-seminomatous
…. germ cell tumors arise from the epithelium of the semineferous tubules and remain localized for long periods of time. they may spread through lymphatics. they respond well to chemotheraphy and are extremely radiosensitive. therefore, they are on of the most curable cancers
seminomas
…. germ cell tumors spread earlier, are less radiosensitive and utilize the hematogenous and lymphatic routes, with the lungs and liver often involved at the time of diagnosis
non-seminomatous
…% of early stage seminomas are cured
