Serous cystadenoma of the ovary
Diagnosis in short

Ovarian serous cystadenoma. H&E stain.
LM cyst lined by a single layer of cuboidal or columnar epithelium with bland nuclear features +/- cilia
Subtypes cystadenofibroma, adenofibroma
Gross cystadenoma: thin walled cyst, usu. unilocular; cystadenofibroma: solid and cystic; adenofibroma: solid
Site ovary - see ovarian tumours
Clinical history +/-abdominal distension, +/-abdominal pain
Symptoms mass lesion
Prevalence common
Prognosis benign
Clin. DDx other ovarian tumours
Treatment cystectomy or oopherectomy

Serous cystadenoma of the ovary is a common benign finding in the ovary.

It is also known as ovarian serous cystadenoma. It is unrelated the the pancreatic serous cystadenoma.

Serous cystadenofibroma and adenofibroma of the ovary can be considered variants, and are also dealt with in this article.

General

Gross

Cystadenoma:

  • Usually unilocular.

Cystadenofibroma and adenofibroma:[3]

  • Solid or solid and cystic.

Image

Microscopic

Features:

  • Simple epithelium with cilia - key feature.
    • Cell morphology: columnar, cuboidal or flatted.

Note:

  • May have calcifications - uncommon.[4]

DDx:

Note - the following may be lumped with this entity:

  • Serous cystadenofibroma.
  • Adenofibroma.

FALLOPIAN TUBE AND (PARTIAL) OVARY, LEFT, RESECTION:
- COMPATIBLE WITH SEROUS CYSTADENOMA.
- BENIGN OVARIAN PARENCHYMA WITH FOCAL EDEMA AND A BENIGN CALCIFICATION.
- FALLOPIAN TUBE WITHIN NORMAL LIMITS.
- NEGATIVE FOR MALIGNANCY.

FALLOPIAN TUBE AND OVARY, LEFT, UNILATERAL SALPINGO-OOPHORECTOMY:
- OVARY WITH BENIGN SEROUS CYSTADENOFIBROMA.
- FALLOPIAN TUBE WITHIN NORMAL LIMITS.
- NEGATIVE FOR MALIGNANCY.

FALLOPIAN TUBES AND OVARIES, BILATERAL SALPINGO-OOPHRECTOMY:
- BENIGN OVARIAN SEROUS CYSTADENOFIBROMA (BILATERAL).
- FALLOPIAN TUBES WITHIN NORMAL LIMITS.

Atypical

FALLOPIAN TUBE AND OVARY, RIGHT, SALPINGO-OOPHORECTOMY:
- BENIGN SEROUS CYSTADENOMA AND SEROUS CYSTADENOFIBROMA WITH FOCAL ATYPIA,
  SEE COMMENT.
- FALLOPIAN TUBE WITHIN NORMAL LIMITS.
- NEGATIVE FOR MALIGNANCY.

COMMENT:
A small focus of the sampled tissue has a complex architecture, compatible with a
borderline tumour; however, it represents less than 10% of the lesion. Thus, the 
lesion is best classified as benign with focal atypia.
