Notes on Testicular tumors

Germ cell tumors are MORE COMMON than epithelial cell tumors in male (unlike female)

Germ cell tumors
------------------------------
(1) Seminoma - painLESS; 15-35yo; uniformly brown with lymphoid stroma; cytoplasmic clearing due to glycogen; PAS positive; modest increase in beta hCG; radiosensitive; good prognosis (equivalent to female dysgerminoma)

(2) Embryonal carcinoma - painFUL; aggressive; large, hyperchromatic nuclei; grandular/papillary; +/- increase in AFP, hCG

(3) Yolk sac/endodermal tumor - yellow, mucinous; MC testicular tumor in infants

Non-Germ cell tumors
------------------------------
(1) Leydig cell tumor - Reinke crystals; androgen production (converted to estrogen via aromatase); gynecomastia; precocious puberty; large round cells with granular eosinophilic cytoplasm

(2) Sertoli cell tumor - eosinophilic cytoplasm; androblastoma from sex cord stroma
