Microscopic evaluation

Attempt to classify into either of the following:

Type Subtype Typical microscopy findings Image
Functional cyst Follicular cyst Graafian Follicle, Human Ovary (3595817584).jpg
Corpus luteum cyst
  • A convoluted cyst lining of luteinized granulosa cells[2]
  • A prominent inner layer of fibrous tissue[2]
  • An outer layer of theca cells[2]

Cystadenoma Serous cystadenoma Cyst lining consisting of a simple epithelium, whose cells may be either:[3]
  • columnar and tall and contain cilia, resembling normal tubal epithelium
  • cuboidal and have no cilia, resembling ovarian surface epithelium

Mucinous cystadenoma Lined by a mucinous epithelium Histopathology of lining of a benign mucinous tumor of the ovary.jpg
Dermoid cyst Well-differentiated components from at least two germ layers (ectoderm, mesoderm and/or endoderm).[4] Histopathology of ovarian dermoid cyst.jpg
Endometriosis At least two of the following three criteria:[5] Histopathology of ovarian endometrioma.jpg
Borderline tumor Atypical epithelial proliferation without stromal invasion.[6] Histopathology of seromucinous borderline tumors.jpg
Ovarian cancer Many different types, but generally severe dysplasia/atypia and invasion.
Simple squamous cyst Simple squamous epithelium and not conforming to diagnoses above Histopathology of simple squamous cyst wall.jpg
