Presentations
Typically a cyst with more or less of the ovary.
Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth

Gross processing
The specimen is generally not inked.
Gross report
Example:
| (Labeled - ___.) The specimen is received in formalin and consists of an ovary with a cyst, and attached portion of the fallopian tube, in total measuring ___. The capsule of the ovary and the cyst is tan-pink and smooth. The cyst is << intact / collapsed>>{{, with a wall defect measuring _ cm}}. Upon {{further}} opening the contents of the cyst consists of ___. The cyst lining is tan-pink and smooth, with a wall thickness of __. There are no papillary excrescences. Cut sections of the ovary reveal solid, white and whorled parenchyma, and no gross lesions. The attached fallopian tube fragment measures ___, and displays fimbria. Cut sections of the tube reveal a patent lumen. Representative sections are submitted for microscopic examination in __ cassettes. |
Microscopic evaluation
If there are solid components, evaluate those as ovarian tumors.
Attempt to classify cysts into either of the following:
| Type | Subtype | Typical microscopy findings | Image |
|---|---|---|---|
| Functional cyst | Follicular cyst |
|
.jpg)
|
| Corpus luteum cyst | 
| ||
| Cystadenoma | Serous cystadenoma | Cyst lining consisting of a simple epithelium, whose cells may be either:[3]
|
|
| Mucinous cystadenoma | Lined by a mucinous epithelium | 
| |
| Mature cystic teratoma (dermoid) |
Well-differentiated components from at least two germ layers (ectoderm, mesoderm and/or endoderm).[4] | 
| |
| Endometriosis | At least two of the following three criteria:[5]
|
| |
| Borderline tumor | Atypical epithelial proliferation without stromal invasion.[6] | 
| |
| Ovarian cancer | Many different types, but generally severe dysplasia/atypia and invasion. | .jpg) | |
| Simple cyst / simple squamous cyst |
Simple squamous epithelium and not conforming to diagnoses above |
