Bilateral germ cell tumour is .
Ans. is c i.e. Embryonal cell carcinoma Friends, this is one of those type of questions where we will derive a correct answer by ruling out other options. Let see, Option 'a' : Dysgerminoma "They are bilateral in about 10% of cases". Option 'b' : Immature teratoma "In a premenopausal patient whose lesion appears to be confined to a single ovary, unilateral oophorectomy and surgical staging should be performed. For a postmenopausal patient, a total abdominal hysterectomy and bilateral salpingo-oophorectomy may he performed. Contralateral involvement is rare, and routine resection or wedge biopsy of the contralateral ovary is unnecessary." Coming on to Option 'c' with embryonal cell carcinoma. It is a rare type of Germ cell tumor and so is the information available on at. The only information I could lay my hands was : Options 'c': Embryonal cell carcinoma The primary lesions tend to be large, and about two thirds are confined to one ovary at the time of diagnosis Option 'd' : Endodermal Sinus Tumour (EST) It is unilateral in 100% of cases. Considering all above options I choose embryonal cell carcinoma as the option of choice I have provided you with all related references, you are free to have your opinion.
