Sera from eleven patients with gonadal germ cell tumors were tested for alpha-fetoprotein (AFP) by counterelectrophoresis. Ovarian neoplasms containing either the endodermal sinus tumor (EST) or dysgerminoma and half of the testicular embryonal carcinomas elaborated the protein into the serum. The presence of AFP in the serum seemed to correlate with early metastasis or a fatal outcome. That th...

Krukenberg tumor is a metastatic ovarian tumor with its primary site being the gastrointestinal tract. The pathogenesis of Krukenberg tumor formation is still in its hypothetical stage though the current understanding suggests lymphatic, hematogenous and transcoelomic as the 3 major routes of metastasis. We believe transcoelomic spread in association with ruptured ovary during the monthly proce...

This paper describes a rare finding of an inguinal ovary in an adult woman who presented with pelvic pain. Inguinal ovary may occur if the gubernaculum fails to attach to the uterus or if the canal of Nuck remains open during fetal development.

BACKGROUND Yolk sac tumor (endodermal sinus tumor) is a rare malignant germ cell tumor arising in the testis or ovary. Extragonadal yolk sac tumor is even rarer and has only been described in case reports. Due to the rarity of the tumors, the appropriately optimal treatment remains unclear. We report a case of yolk sac tumor in the seminal vesicle. CASE A 38-year-old Asian male presented with...
