A 57-year-old Brazilian woman with a giant mucinous cystadenocarcinoma of the ovary: A case report

Abstract

Introduction. Giant cystadenocarcinomas of the ovary are rarely described conditions. Case presentation. The authors describe a 57-year-old Brazilian woman who presented with an increase in abdominal girth in February 2003. Imaging studies showed a giant abdominal pelvic mass with probable origin in the right ovary. Cancer antigen-125 was elevated, while carcinoembrionic antigen and alpha-fetoprotein were normal. Total abdominal hysterectomy, bilateral salpingoophorectomy and omentectomy were done. The mass weighed 40Kg, and the histopathology study revealed a mucinous cystadenocarcinoma. She underwent chemotherapy with paclitaxel and cisplatin with no side effects. Under follow-up for more than 10 years, she is asymptomatic and with normal imaging and laboratory parameters, including the cancer antigen-125 marker. Conclusion: This huge tumor evolved for a long time unsuspected and without metastases in a patient from a developing region. The diagnostic and management challenges posed by this unexpected and unusual presentation of an ovarian cystadenocarcinoma are discussed. © 2014de Lima et al.; licensee BioMed Central Ltd. ©2014 de Lima et al.; licensee BioMed Central Ltd.
