Abstract

|
Extra-ovarian yolk sac tumor arising in the omentum is extremely rare. As yolk sac tumor originated from the omentum has been rarely reported, its clinical information is very limited. The authors encountered a case of yolk sac tumor originated from the omentum, and reported the case herein. A 32-year-old woman was presented with developed low abdominal distension for a month. Magnetic resonance imaging findings were suggestive of ovarian malignancy with ascites and peritoneal seeding nodules. Explorative laparotomy was performed and then the findings from frozen biopsy of omentum were suggestive of poorly differentiated tumor though whether it was primary or metastatic was uncertain. Thus, staging laparotomy were performed. Histopathology confirmed that the tumor was a yolk sac tumor of omentum origin. Then, 6 cycles of postoperative adjuvant chemotherapy at intervals of 3 weeks were performed using bleomycin, etoposide, and cisplatin regimen. Four-year outpatient follow-up thereafter showed no relapse.
