Ovarian serous cystadenoma is a noncancerous type of tumor of the ovary.[1] It is typically larger than 1cm in diameter and presents with signs and symptoms of a growth in the pelvis or is discovered when investigating something else.[1][2] A fifth occur in both ovaries at the same time.[2]

It is a type of serous tumor of the ovary made up of cells that look similar to fallopian tube epithelium.[1]

Test include ultrasound or colour doppler study to know about size and nature of mass and sometimes CECT. Blood investigation includes CA-125 level for screening and further CEA, beta hCG levels, AFP, CA19-9, LDH level to confirm diagnosis.[citation needed]

It is the most common ovarian neoplasm, representing 20% of ovarian neoplasms.[3]

Diagnosis

Serous cystadenomas are diagnosed by histomorphologic examination, by pathologists. Grossly, they are, usually, small unilocular cysts that contain clear, straw-coloured fluid. However, they may sometimes be multilocular. Microscopically, the cyst lining consists of a simple epithelium, whose cells may be either:[4]

  • be columnar and tall and contain cilia, resembling normal tubal epithelium
  • be cuboidal and have no cilia, resembling ovarian surface epithelium

Epidemiology

Ovarian serous cystadenoma accounts for the largest proportion of benign ovarian tumours, making up over 50–80% of all benign epithelial ovarian tumours. Its prevalence peaks between 60–70 years of the human lifespan. Serous ovarian cystadenocarcinomas account for ~25% of serous tumours.[5]
